Copper sulphate or blue vitriol: Use against fungus on walls and vermin in the garden. How copper sulfate is used against fungus How to remove fungus in a wooden bath

The mold that appears in the bath can cause a lot of trouble, one of which is the damaged interior of the room and, moreover, it negatively affects our well-being and health. And even in the case when all the rules of construction and operation seem to be observed, sometimes it becomes difficult to avoid its appearance.

Consider what are the causes of mold, how to prevent it, and how to get rid of mold in the bath.

Why does mold appear

  • Poorly or incorrectly waterproofed foundation.
  • Poor-quality wood infected with a fungus was used, or antiseptic treatment was not carried out.
  • The ventilation system is poorly or incorrectly made.
  • Not, which leads to their freezing.

What to do to prevent mold

  1. For the construction of a bath, a forest harvested in winter should be used., during the period of lack of movement of juices in the wood. The foundation is laid in the fall, and the roof frame is erected in the spring.
  2. All lumber must be carefully checked at the base, and if infected products come across, then they should be rejected immediately, and it is best to look for another base.
  3. Despite the fact that the price of dried lumber is much higher, its use will not allow the initial conditions for mold to appear..
  4. When using uncured lumber, be aware that the ventilation system must be of high quality, or for some time to create conditions for artificial ventilation of the bathhouse. The operation of a bathhouse made of undried material immediately after construction is undesirable. She needs to be dried.
  5. If there is free space under the floor in the bath, then it must be ventilated.
  6. You should take care of high-quality ventilation of the attic space, or, if there is an attic in the bath, about good and washing.
  7. If the bath is built using frame technology, then vents must be made in the frame ribs.

Removing mold in bathrooms

Preventive actions

Methods for the destruction of mold in the bath are effective when the root causes of its appearance are eliminated. It occurs most quickly at very high humidity over 95%, temperatures over 20 degrees and, of course, in the absence or poor ventilation of air.

Therefore, when deciding what to do if there is mold in the bath, then first of all it is necessary to check the condition of the ventilation system. If necessary, it is cleaned or even redone.

Dirt on the walls and in the corners is also the cause of the appearance and spread of mold. Therefore, the premises of the bath must be kept clean, the walls themselves cannot be cleaned. Wet cleaning should be carried out after each use of the bath, preferably with the use of ordinary whiteness.

After all activities, the bath should be thoroughly dried. And the condition of all rooms must be constantly monitored to prevent the occurrence of mold again.

Folk ways to get rid of mold

It is not easy to deal with mold with your own hands, but it is possible.

It is important to understand that for all treatments, instructions for the use of folk remedies must be followed.

  1. Sulfur.

First of all, during processing, all ventilation openings must be closed to prevent leakage of sulfur combustion products. Sulfur is placed in a ceramic or metal vessel at the rate of 20 grams per 10 meters of cubic space.

Combustion products, and they are sulfur dioxide, are harmful both to mold and to human health, therefore it is impossible to be indoors at this time. When tightly closed should be within 6-9 hours. Then a box with quicklime is placed, which will absorb sulfur dioxide and also dry the room.

Caution: Always wear breathing protection when installing the lime box.
Otherwise, you can harm your health up to death.

  1. Bleaching powder.

First, the walls are cleaned of mold. A concentrated solution of bleach and quicklime is made and the places where mold occurs are treated with this solution. At the same time, wear gloves and a respirator, because the small size of the spores allows them to enter the human body through the skin.

  1. Inkstone.

Pretty gentle solution for wood, but strongly acting on mold. The composition of the solution per liter of water is as follows: iron vitriol - 22 g, aluminum potassium alum - 44 g, table salt - 18 g. Using a brush, roller or spray gun, all surfaces are treated.

  1. In addition, when deciding how to treat a bath from mold, you can also use professional preparations, which the industry offers in a wide range.

Tip: After any mold removal solutions have been used, the surface should be treated with clean water.
The fact is that such solutions have a harmful effect on the human body.

Output

Of course, when deciding how to remove mold, first of all, you need to think about the fact that its appearance is easier to prevent than to remove after it appears. Simple rinsing will not remove the dirt, so it is necessary to wash the bath regularly and thoroughly. In addition, periodically treat with preventive measures.

Our portal is ready to provide additional information on this issue, which is also contained in the proposed photos and videos in this article.

It is not necessary to use special means against the mold that has appeared - if the problem is not started, then simpler and cheaper substances can be dispensed with. One option is vitriol.

The use of this method is possible both in an apartment and in non-residential premises (cellar, garage, barn, attic, and so on).

What is it, how to breed and how to properly use this tool to get rid of the fungus on the walls - we will understand below.

What is vitriol, and how does it happen?

Vitriol is a sulfate salt of divalent metals (if you give a definition from a chemistry textbook). Vitriol is copper, iron, nickel, zinc, manganese. There are other types of connections, however, only copper is almost always used to remove mold, so we will only consider it.

Copper sulfate (or copper sulfate, or sulfur-copper salt, or CuSO4) is the most important of the copper salts. It is used in construction, agriculture, food industry, medicine, industry.

Outwardly, it looks like blue crystals.

About the use of copper sulfate (video)

What vitriol should be used against mold and where can I get it?

Most often, the fight against mold is carried out with the help of copper sulfate, much less often - iron is used. The agent is used in the form of an aqueous solution.

You can buy copper sulphate in hardware stores, in building stores, in stores for summer cottages and gardening.

Approximate prices for packages:

    100 grams: about 40-50 rubles;

    300 grams: about 100-120 rubles;

    1 kg: about 230-250 rubles;

    25 kg (bag): 4800-5300 rubles.

What is needed to remove mold with vitriol?

To prepare and apply the solution, we need:

    Copper sulfate - 100 grams.

    Warm water - 10 liters. The container is ceramic or metal with an enamelled surface.

    Vinegar - 200 ml (not necessary, but will enhance the effect).

If it is necessary to process a large area, then the “water-vitriol” ratio should remain approximately the same - 100 to 1. That is, 200 grams of vitriol is needed for 20 liters of water, and 500 grams for 50 liters of water.

Additionally you will need:

    Sponge, or brush, or spray gun - for application.

    Spatula, metal brush (for cleaning the surface).

    Soap-antiseptic.

    Sandpaper.

Means of protection:

    Rubber gloves.

    Respirator.

    Clothing must cover the entire body.

How to breed vitriol from mold?

Now about how to dilute the solution.

IN 10 liters of warm (about +40º) dissolve 100 g of vitriol in water. The solution can be stirred with any improvised piece of wood.The temperature of the water may be lower, but in warm water the vitriol will dissolve faster.

For convenience, you can dilute the product in 4-5 liters of water, and after dissolving it, add liquid to the full volume.

To enhance the effect, the solution can be diluted:

    Vinegar (9%): 25-40 ml per 10 liters of water and 100 grams of vitriol.

    A few drops of tea tree oil.

    Any product containing chlorine.

You can store the prepared solution of vitriol for up to 3 months (at room temperature), or up to 1 year if it is removed in a cool place. For storage, use a tightly closed ceramic or glass container. It is impossible to store the solution in a metal container.

Surface preparation and work

Before applying vitriol, it is necessary to prepare the surface:

    If possible, ventilation of the room is provided (windows open, hoods turn on).

    On the walls that are affected by mold, the decorative coating is removed. The removal of the coating is carried out depending on its type (wallpaper - torn off, plaster or paint - scraped off with a spatula).

    With deep penetration of spores, the surface must be cleaned with sandpaper.

    It is recommended to wash the places that were affected by the fungus with soapy water before using vitriol, and then let them dry. This is especially useful if black mold has grown on the wall.

    Put on protective equipment.

    Prepare a solution of vitriol (how to dilute - described in the paragraph above).

    Using a sponge (or brush, or spray gun), apply the solution to the wall.

    Let the surface dry. Depending on the level of humidity in the room and the area of ​​the treated area, it can take from 2-3 to 10-12 hours (4-5 on average).

    If there was a lot of rot, or mold was on the wall for a long time, it is recommended to repeat the treatment 3-5 times.

    After complete drying of the surface - you can do the finishing.

Please note: you can remove mold with this solution. However, if the cause of the appearance of rot is not eliminated, it is possible that after some time it will appear again, and repeated removal will be required.

Is vitriol dangerous, and what are the symptoms of poisoning?

First, about the dangers of copper sulfate (both in the form of granules and in the form of a ready-made aqueous solution):

    In case of contact with the skin - there is no danger, however, hygienic treatment is required (wash off the solution with soap and water).

    Contact with the solution in the eyes may cause burns. In this case, immediately rinse the eyes with plenty of water.

    Dosage that can lead to poisoning: 0.5 grams of powder in dry form and 11 mg / kg - by inhalation.

    The lethal dosage is 45-125 grams (when swallowed dry). The exact figure depends on body weight, health status and age.

Stages of work

Symptoms of poisoning:

    nausea and vomiting;

    pain in the stomach;

    increased heart rate;

    general deterioration of health, weakness;

    allergic reaction;

    skin rashes, itching.

If these symptoms are felt when working with vitriol, it is necessary:

    stop work immediately;

    if the work was carried out indoors, and the symptoms appeared due to inhalation of the substance, leave the room and ventilate it;

    seek medical attention.

Copper sulphate poisoning is rare. It is possible with:

    accidental or intentional ingestion (means in dry form or solution);

    prolonged stay without a respirator in an unventilated area in which the solution is used.

Precautionary measures

When preparing a solution

If mold has appeared in the bath, you need to pay special attention to the ventilation system. Humid and warm air creates ideal conditions for the development of this microscopic fungus. If you do not react in time, then in a short period of time spores can penetrate to a depth of several centimeters deep into the walls, and it will be extremely difficult to remove them. Even at the initial stage, this is not an easy task. The colonies of this fungus are very mobile and easily move from one place to another. Therefore, you need to process the entire room (premises) at once.

Another nuisance is that not only the mold itself is harmful to humans, but also many chemicals designed to fight the fungus. Therefore, process the premises, observing all possible precautions.

Spots are clearly visible on the wood - traces of the activity of the fungus

So, first we check the ventilation system. We clean blockages and eliminate possible damage. You can install fans near the ventilation grills that will activate the movement of air.


The simplest solution is to use a special primer. Only when purchasing a remedy, make sure that it is not preventive, but is intended specifically for mold removal. And choose a composition that can process wood. When processing, he strictly observes all recommendations: dosage, processing time and safety precautions.

There are many ways to get rid of mold using improvised means. Almost all of them are not harmless: some have a destructive effect on wood, some are harmful to human health. But the mold itself is dangerous, so you have to put up with these disadvantages of "treatment". You just need to be careful about safety and after each treatment thoroughly ventilate and dry the premises, while not forgetting to wear protective equipment.

Folk remedies for getting rid of mold

  1. Sulfur. During processing, close the ventilation holes, plug the cracks. Ignite lumps of sulfur in a ceramic or metal vessel. For 100 cubic meters you need 200 grams of sulfur, how much you need, calculate based on the volume of the room. The method is quite dangerous - when sulfur is burned, sulfur dioxide is formed, which kills all fungi. It can also kill you if you don't leave the room quickly enough. Therefore, quickly go out, close the door tightly and do not go inside for 6-9 hours (make sure that no one else goes there either). Then you need to put a box with quicklime in the room. It will absorb the remaining sulfur dioxide and dry the room.
  2. Bleaching powder. First, the walls are cleaned of mold. Do not forget to wear gloves and a respirator: the spores are so small that they even enter the body through the skin, not to mention the air. Then bleach and quicklime are dissolved in a small amount of water. Walls are treated with this solution. There is another option: bleach with formalin (also diluted in water). Mold, perhaps, such treatment will kill, but what will the walls look like after that? This is a question.
  3. Inkstone. A more gentle solution for wood, but deadly for mold: 22 g of iron sulfate, 44 g of potassium alum, 18 g of table salt. All diluted in one liter of water. Thoroughly treat all surfaces (with a brush, roller or spray gun).
  4. The tree is treated with the following compositions (based on 10 liters of water):
  • sodium fluoride (1-1.5 kg);
  • 1 kg of copper sulfate;
  • 1.5 kg of iron sulfate;
  • 0.5 kg of each chemical;
  • 0.5 kg of copper sulfate and 1-1.5 liters of acetic acid;
  • 0.4 kg of boronic acid, 0.9 kg of borax, 1.4 l of vinegar (table);

The solutions are heated to a temperature of 50-70 ° C, applied with a brush or sprayed onto all damaged surfaces. Let dry. A month later, the treatment is repeated.


Processing wood from decay can be done with a paint brush

If the lesion is small, you can try to get rid of it by wiping with alcohol. Not only will this remove the mold, but it will also dry out the area of ​​wood.

In general, like every phenomenon, mold is easier to prevent than to remove. To prevent the occurrence of this trouble, take care of ventilation and regular drying. And one more thing: mold “loves” dirt. Wash your bath thoroughly and regularly. Rinsing with clean water is clearly not enough to remove dirt. It is advisable to carry out periodic treatments with prophylactic agents.

On the Internet, there is a recommendation to wash the shelves with ordinary dishwashing detergents, as well as to use "Whiteness" - chlorine-containing bleach. On sale there are wood hygiene products specially designed for bath rooms and saunas, for example Tolu 600ml. Tolu is produced in Finland and is specially designed for sauna owners. The composition is designed in such a way that there is no need to use a brush, as it can damage the structure of the tree, as a result of which the wood will quickly darken.

Tolu is sold in 600 ml plastic bottles. The cost of one bottle is about 200 rubles.

This problem is faced by the owners of the baths, who equipped the steam room, but the ventilation is insufficient. If you do not pay attention to the mold in the bath, then it can penetrate deep into the walls, which will make it much more difficult to get rid of it. Recipes and tips will be relevant to most people who have their own steam room.

How to get rid of the fungus in the bath

A room in which the heating system does not work on a permanent basis is an ideal environment for the formation of fungus. Particular importance should be given to wooden buildings, because they are in the main risk group. Mold can spread to any surface, the main condition for rapid development is maximum humidity. Colonies develop on ceilings, floors, walls, or in corners. If a certain area is not sufficiently insulated, as is often the case in do-it-yourself steam rooms, then mold will appear there first.

If you notice the first signs of a fungus, you need to immediately begin to remove it. There are three main ways to destroy mold spores: mechanical, folk remedies, store preparations. The conditions are:

  • The first option is to clean the damaged surface with a brush or grinder. If, during the elimination of the fungus, damage to the entire timber was revealed, then it must be completely replaced.
  • Folk remedies for getting rid of the fungus or ready-made store mixes involve the treatment of infected areas with aggressive substances of superficial or deep penetration.

Treatment of the ventilation system

Before proceeding with the disinfection of walls, ceilings, corners or floors from fungus, the ventilation system should be checked and well treated. The first step is to open the shutters and examine the cavity, which serves as a ventilation duct. They clean any blockages, dirt, eliminate acquired damage. Many owners of baths eliminate the source of the appearance of the fungus by installing a fan near the ventilation grilles. The device contributes to the necessary movement of air.

You can process the ventilation system with a specially designed primer. The remedy should go exclusively to eliminate the fungus, and not for prevention. You should choose a drug that works with wood, strictly adhere to the dosage and precautions so as not to hurt yourself or burn your skin. After each treatment, it is necessary to ventilate and dry the bath.

How to remove the fungus in the bath on the walls

Stores offer a wide range of products. How can you remove the fungus in the bath? Most people use the old-fashioned method using copper sulfate - it is considered the most effective. It is necessary to dry the surface thoroughly, make the solution according to the instructions and apply it to the walls with a brush. The procedure should be repeated after a couple of weeks. How else can you treat the walls from the fungus? Surfaces are coated with 70% acetic acid or whiteness in pure (not diluted) form. This is a temporary solution to the problem: first, the ventilation system should be repaired.

What to do if a fungus appears on the floor in the bath

Infection of the floor with a fungus in the bath is a common occurrence. It is advisable to disassemble the plank surface with mold, in the process, remove part of the soil, which can also be infected. Damaged boards should be replaced. The rest of the floor of the room must be treated with an antiseptic. To avoid the appearance of mold in the future, the bath must be heated daily, and after use - aired for a long time. In this way, you will get rid of the cause of the appearance of mold and protect yourself from the diseases that mold causes.

How to treat a bath from mold

There are many remedies that help kill mold. They can either be purchased at the store in the form of a ready-made solution, or you can make it yourself. It is better to buy antiseptics for surface and deep use of well-known and proven brands that guarantee the protection of the boards and a positive result in eliminating mold. This is for example:

  • Biotol;
  • Metas-Bio;
  • Ceresite;
  • Dali;
  • Neomid-Bio;
  • Erlin;
  • Pentatos.

From folk remedies, than you can remove the fungus in the bath, choose:

  • Bleach, which consists of quicklime bleach and plain water. It is applied to a dry surface.
  • Copper sulfate: It is sold everywhere in stores that specialize in gardening. If you make a solution per liter of water, then you need to take fifty grams of vitriol, one hundred grams of potassium alum and thirty grams of table salt.
  • Sulfur, the price of which is low, and the result is fast and perfect. In a refractory container (basin, bucket), a sulfur block is set on fire, which, during the combustion process, releases gas, destroying the spores of the fungus throughout the room.
  • Hydrogen peroxide in 20-25% is applied to wood and left for several hours, and then wiped with a rag soaked in water.
  • Plain white, which can be bought at an affordable price in hardware stores. After applying this substance, the walls should be additionally treated with water.

Mechanical cleaning of the surface

If the depth of penetration of the fungus is not very significant, then you can use the mechanical cleaning of the affected area. For this, construction tools and fixtures are useful: a spatula, emery, a metal brush, a grinder. After visible areas of mold have been removed, it is advisable to burn the waste to prevent the development of fungus on other objects. Mechanical cleaning is also used for deep penetration of mold, sawing out a piece of wood and inserting new material there.

Treating wood from a fungus with folk remedies

How to remove the fungus in the bath? Best of all, folk remedies that have been tested by more than one generation help. Bleach, blue vitriol, sulfur checker, hydrogen peroxide and household whiteness do an excellent job with the fungus, they are low in price. When using these compounds, you should follow the instructions for preparation, and also wear a protective mask so that vapors of harmful substances do not enter the body. In the case of a sulfur checker, it is necessary to leave the room, and close the windows, doors and all cracks tightly.

Mold antiseptics

In addition to the mechanical disposal of the fungus or the use of folk remedies, it is recommended to purchase professional preparations. Shop antiseptics of superficial and deep penetration, which are completely different in price, will perfectly cope with mold. How to remove the fungus in the bath for a long time? It is better to stop the choice on products from trusted manufacturers, such as Biotol, Metas-Bio, Ceresit, Dali, Neomid-Bio, because the chemistry of little-known companies may not help, and the money will be spent.

The price of means for removing the fungus in the bath

Many owners decide how to treat the fungus in the bath, starting from the price of the agent and method used. Machining with all the tools will be the most budgetary. A little more expensive than impregnation with folk remedies. The price of store antiseptics is ambiguous. It all depends on the popularity of the manufacturer's brand, but in most cases it is high. There are a lot of options for how to destroy mold - you should choose the one that is acceptable to you.

How to remove the fungus in the bath

Bane is a real threat to people and their property. It not only causes the destruction of the building, but also affects human health. So, it can cause diathesis in a child, severe allergies, which can turn into asthma, migraines, and cardiovascular disorders. Fungus in the bath is a frequent occurrence, because it loves humidity, and in this room there is almost always condensation - ideal conditions for reproduction. So, if you are faced with such a problem, you need to take emergency measures. In this article, you can learn how to get rid of the fungus in the bath and prevent its reappearance.

Dampness is the #1 cause of mold

In the baths, the humidity is always increased - this is a regularity, and nothing can be done about it. If there is no additional heating in the building, most often these are wooden baths, then you are at an increased risk. The fact is that heating allows you to dry the air, walls, and the likelihood of a fungus is reduced. There is no heating - the bath dries out on its own, the walls remain damp longer - this is good for mold.

The reason for the stagnation of moisture can also lie in such factors as the lack of ventilation or its improper equipment, blockage. In this case, the fungus first appears in places where the air movement is the weakest, and then, having grown stronger, it spreads along the wall without problems, and light drafts no longer bother it. If the matter is ventilation, then it is necessary to create it, reinstall it, clean it, install additional fans that will help drive air, dry the room. Next, we will tell you how to get rid of the fungus in the bath, but for now we will consider another reason for its appearance.

Insufficient cleanliness

Many bath owners assume that this is the cleanest room, because it is always humid there, and they neglect to wash the ceiling and walls, believing that it is enough to clean the floors, shelves and accessories. The fungus loves dirt, and coupled with dampness, conditions are generally ideal.

If you have good ventilation, even heating, and mold still appears, then there is not enough hygiene.

What to equip?

Before you get rid of the fungus in the bath, you need to think about your own safety. By scrubbing mold from a surface, you spread its spores in the air, and they can get into your lungs. Before starting the fight, you should purchase the following protective equipment:

  • a respirator will help protect the nasal mucosa and lungs from getting spores of the fungus and chemicals with which you will remove mold;
  • rubber gloves will protect your skin and nails.

This is a necessary equipment, and without it, in any case, do not start the fight against the fungus.

Is it difficult to eliminate the fungus?

Mold spores are very mobile creatures and, as soon as they appear, they begin to spread throughout the room. Treating only visible lesions is not enough; anywhere there may still be black and white fungus in the bath. How to get rid of this pest? The first step is to assess the situation, find all the lesions, take everything out of the room that is not nailed down, and start processing all the walls, ceiling, shelves, floors. It is worth noting that the inventory taken out must also be processed. It is very difficult to get rid of the fungus even at the first stage, not to mention the fact that the spores could have managed to penetrate several centimeters deep into the boards and hide in the cracks. Where to begin?

The first step to getting rid of mold

To begin with, you will need to mechanically clean all visible lesions. Especially carefully inspect every centimeter, even an incomprehensible speck can be a fungus, so do not lose sight of it.

First of all, slowly, carefully, so as not to spread spores throughout the territory, remove the layers of mold with a spatula, go through all the cracks and corners where the fungus was found. Mechanical cleaning is very important, it allows you to remove all superficial lesions that protect deeper ones. After that, you can proceed to the chemical attack.

Don't forget about ventilation

After mechanical cleaning has been carried out, it is necessary to proceed to ventilation. In most cases, it also contains a fungus, there may also be a focus of infection. First, treat the ventilation system with antibacterial agents, it can be ordinary alcohol. It perfectly dehydrates, that is, it dehydrates the surface, it is able to push moisture out of the narrowest cracks, in addition, it destroys mold spores. Do not forget that this substance is flammable, so thoroughly ventilate the room after treatment and proceed to the next step.

You can find specialty primers at the hardware store. They can simply protect the surface from the appearance of mold, or they can contribute to its destruction. Choose a product suitable for your wood and use it to ventilate. Now you can treat all other surfaces in the room with this primer. Next, consider how to get rid of the fungus in the bath in other ways. There are many of them, we offer the most effective.

Sulphur dioxide

It sounds intimidating, but there is nothing easier and more effective than removing the fungus in the bath with sulfur. This procedure is very unpleasant, the substance smells bad, dangerous for all living things, so before using this method, make sure that all possible gaps are tightly closed. Plug tightly the ventilation, the pipe, if the bath is heated by an oven, all small cracks and holes through which a dangerous substance can penetrate. Sulfur dioxide is very dangerous, it will one hundred percent get rid of the fungus, but in no case should you yourself be exposed to it.

If the floors are wooden, it is better to take a ceramic container, if concrete, then it can be metal utensils. Put a few pieces of sulfur there, on the basis that two hundred grams of the substance is needed per hundred cubic meters of the room. Set fire to the sulfur, it will release a gas that is detrimental to the fungus. After it has begun to act, immediately leave the room and close the front door tightly behind you. It is important to use a respirator during arson and during further actions.

After at least six hours, and preferably after nine, take a box with Go to the bathhouse, remove the remnants of sulfur, put a box of lime in its place. It neutralizes the remnants of sulfur dioxide, dries the room, absorbing excess moisture. The box should be in the bath for a day, after which the room is ventilated for the same amount. You can use the bath immediately after airing it.

How to remove the fungus in the bleach bath?

This is also a good option, but it is better not to use it for a wooden bath, since bleach is not very safe for wood.

After cleaning the walls from mold mechanically, it is necessary to dilute the indicated substance in a small amount of water and walk over all surfaces with this solution. There is another option: take 25 milliliters of forty percent formalin per liter of water, add bleach and process the floors, walls, ceiling, shelves.

How to get rid of fungus in a wooden bath?

Sulfur dioxide and a primer are ideal for wood, they will not damage it, but there is another gentle method of getting rid of mold in a bath. It is necessary to take 22 grams of ferrous sulfate, 44 grams of aluminum alum and 18 grams of ordinary table salt per liter of water. Dip the roller in the solution, treat all surfaces after mechanical cleaning of the fungus.

You can also use the following recipe, but preheat the mixture to seventy degrees. You will need one and a half tablespoons of vinegar (not acid), a pound of boric acid and a kilogram of borax. Dissolve the ingredients in a small amount of water.

Both recipes are effective, but still rather weak, they may not remove all the fungus the first time, so treat it again in a month.

Prevention

Of course, preventing the appearance of fungus in the bath is easier than getting rid of it. If you have ventilation, still do not forget about ventilation. They should be made not only after the use of the bath, but also when you do not use it, because the water can stagnate and then evaporate. Ventilate at least once a week for six hours.

Carry out preventive treatments with iron sulphate or other substances. Remember that after using chemicals, you need to ventilate the bathhouse, then rinse the walls so as not to harm your health. We hope that this publication on how to get rid of the fungus in the bath will be able to help.
