Condensate can collect in places where temperatures change and in closed spaces: rooms, vessels, cavities. In stagnant moisture, spores of a fungus (mold) inevitably start. Mold is a living organism that grows under certain conditions. Depending on the material of the solid surface, it has different names and classes, in total there are about 400 types of household mold. However, they all originate in the same living conditions, which means that the “deadly” conditions for them are also the same. That is, we can remove all types of household mold with the same means..

How mold is etched away

Household fungus is afraid of literally everything: draft, household and food chemicals, salt, frost, heat, ultraviolet radiation and other tangible factors that are relatively safe for humans. Some of these phenomena destroy it, some – stop development..

There are several ways to kill fungus:

  1. Place it in an unacceptable environment. After removal from the “home” place, he no longer interferes with the person.
  2. Destroy it on the spot. Removal from the surface will have a temporary effect. If indoor conditions do not change, it will reappear.
  3. Eliminate fungal spores. This is already more meaningful: to treat the place affected by mold with an active compound that will destroy the spores of the fungus that have eaten into the material.
  4. Eliminate conditions favorable for its growth. Mold appears in places with stagnant humid air. Elimination of this factor will prevent the fungus from multiplying..

An additional risk factor for mold is that it not only feeds on moisture, but also retains it. Chemical reactions in disputes affect any material, especially wood.

Molds and recipes for mold control

As we already mentioned, there are fungus agents in every pharmacy or household chemical store. Let’s try to understand the degree of effectiveness of each of them, noting the advantages and disadvantages.

Bleach

Destroys most of the known species of not only domestic but also outdoor mold. The whiteness bleach contains a large percentage of chlorine, which perfectly disinfects materials and liquids, destroying all microorganisms. The undisputed leader in efficiency.

Disadvantage. It is toxic when it reacts and irritates the mucous membranes. From vapors you can get light poisoning, from getting inside – acute.

Price. 1 liter of “Whiteness” costs about 0.5 cu. e.

Ammonia (aqueous ammonia)

Effective for hard surfaces (non-porous) – countertops, tiles, glass. Not suitable for porous materials such as wood, drywall.

Disadvantage. Up to 50% of the liquid evaporates or loses its properties without having time to react. Pungent odor, may cause serious irritation.

Price. Is 1 liter of aqueous ammonia solution worth? 1.8 cu e.

Borax (borax, tinkal, high-temperature flux)

The name of this substance comes from the Arabic “byurak” – white. It actively reacts with water, forming an aggressive environment that is safe for humans and coatings. Especially effective on glazed surfaces (sanitary ware, enamel).

Disadvantage. Available in powder form, which is inconvenient to use – you have to prepare a solution.

Price. 1 kg of technical borax will cost about 1 cu. e.

Baking soda (sodium bicarbonate)

Like borax, it is an alkali, only more readily available through distribution. Absolutely harmless and non-toxic, does not emit harmful substances.

Disadvantage. Low reactivity (safety tribute) and relatively high price.

Price. 1 kg of purified soda suitable for food purposes costs about 1.7 cu. e. Baking soda of the 2nd grade will cost significantly less – 0.25–0.3 cu. e. / kg.

Hydrogen peroxide 3% (perhydrol)

Active antiviral, antifungal and antibacterial agent. Its original purpose is to kill fungus, so peroxide is the best choice for removing mold. It disinfects the surface and is harmless to humans even with direct ingestion.

In industry, perhydrol is actively used as a disinfecting component for water and other media. If desired, you can purchase peroxide of a higher concentration – up to 35%. Such a “strong” (active) composition is used for water preparation and pool cleaning.

Disadvantage. The pharmaceutical preparation does not corrode dark spots from the fungus. Highly concentrated liquid is not sold in stores.

Price. A pharmacy pack of 100 ml costs 0.2 cu. That is, 1 liter of technical peroxide 5% costs about 0.65 cu. e. Peroxide of a higher concentration costs from 1.2 cu. e. / l.

Vinegar 7-9%

Destroys about 80 types of fungus. The weak acid is safe for human skin. Unlike borax and soda, it creates an acidic environment in which mold spores die.

Disadvantage. Corrosive vapors and odor that lasts a long time.

Price. 1 liter of 9% table vinegar costs about 0.7 cu. e. Vinegar essence 70% costs about 2.5 cu. e. / l.

By performing a simple analysis, we can make sure that two substances remain in the “leaders”:

  1. Bleach is absolutely effective, but requires respiratory and vision protection. Suitable for high volume and advanced cases.
  2. Hydrogen peroxide (pharmacy) – is absolutely harmless, but works with mild degrees of damage. For more complex ones, you will have to purchase technical perhydrol.

Useful tips for dealing with mold

  1. Do not try to wash off the fungus with warm or hot water and soap. The outer part will be removed, but the spores will receive food in the form of soap fats and warm moisture for reproduction.
  2. Another recipe for an antifungal solution: 1 part water, 3 parts baking soda and 1 part washing powder.
  3. Only the fungi themselves are removed mechanically (with a brush), but not the spores. Mold will reappear.
  4. Ammonia is found in all windshield wipers.
  5. To prevent the formation of spores, it is enough to ventilate the room 2 times a day for 10 minutes. The more intensive the ventilation and the drier the room, the less the likelihood of fungus formation.
  6. If the room cannot be ventilated for some reason, install a moisture trap or dehumidifier there. Such devices are used by painters to dry rooms in which wallpaper is pasted..
  7. Heat and frost do not kill spores, they only stop their growth. With the return of comfortable temperature and humidity conditions, the development of the fungus continues.

Mold is harmful and even hazardous to health. Not only does it intensively process the oxygen we need, but it can also cause a whole bunch of respiratory diseases. Of course, this requires a relatively large amount of fungus, but it always comes from a small amount. Eliminate the slightest manifestations of the fungus and take care of your health.
