One of the biggest concerns about home care in high humidity areas is the appearance of mold on the walls. This type of fungus develops in poorly ventilated areas, producing black spots that become embedded in the paint of the rooms, causing an unpleasant and unhygienic appearance.
It is therefore important to check the house regularly and be attentive to any appearance of dirt in the corners or walls. Indeed, exposure to mold spores not only causes aesthetic problems within the home, but can also be harmful to health, leading to the development of respiratory problems.
Once the mold colony is detected, it is important to act quickly and try to completely eliminate it as quickly as possible, otherwise it could continue to spread and take hold in other areas, further complicating the task. There are various useful methods that will allow you to remove mold and black stains from the wall with basic household cleaning products.
How to Remove Mold and Black Stains from Walls
Although there are several alternatives to remove mold and black stains from the walls of the house, one of the most effective and accessible to any user is bleach. This product is a powerful disinfectant, so it can remove mold from any surface.
To apply, mix one part bleach with three parts water in a bucket and stir to combine completely. After that, apply it to the area of the wall that has black stains with a spray bottle or a damp microfiber cloth.
Next, scrub the area with a stiff-bristled brush until all traces of mold are removed from the wall. Finally, use a dry microfiber cloth to remove any excess product and allow the surface to air dry on its own, avoiding placing anything in front of it as moisture may build up again.
Bleach is a strong product, so it is advisable to apply it with rubber gloves and not to mix it with other cleaning products – especially ammonia – as it can generate highly toxic gases . Additionally, this method is ideal for surfaces such as tiles or painted walls, although it is not recommended for wooden or cement walls.
Another of the most useful options is white vinegar, one of the most common basic products when cleaning the house. It works as a mild acid that removes many mold-damaged surfaces.
To apply, spray areas of the wall with black spots and let sit for an hour. After that, scrub with a brush and rinse the area with a damp microfiber cloth to remove any excess. This method is ideal for surfaces like wood and cement, unlike bleach.
Another of the most common alternatives is to use products on the market specifically designed to remove mold and black spots. These usually contain components such as chlorine or citric acid, which act as fungicidal agents.
Nevertheless, it is always advisable to read the manufacturer’s instructions and safety warnings before applying such items. In addition, some of these products are resistant and require subsequent ventilation.
How to prevent mold and black spots from appearing on the wall
Although it is possible to remove mold and stains from the wall, it is advisable to take several preventative measures to prevent the return of mold, taking into account the humidity level. To do this, ventilate the rooms properly by opening the windows daily. In addition, it is possible to control the environment using dehumidifiers, allowing the relative humidity of the house to be maintained between the recommended values of 30% or 50%.
It is also recommended, when air conditioning rooms in the house, to use antifungal paints, specially formulated to resist the formation of mold. These are available in a large number of stores and in a wide range of colors.
