If you found stains of moisture or mold on the walls of an environment inside your home, you need to do something urgently. The indoor humidity can generate many problems and is also harmful to health.
But to know how to act, you must first know precisely the origin of the humidity. Here we give you some clues so you can guide your search.
Moisture of the floor.
If the humidity of the interior walls is concentrated mainly at the height of the floor, it is likely that the humidity comes from there. This is known as rising humidity. This moisture problem is almost always caused by obsolete pipes or by the proximity of groundwater.
Water filtration from the outer walls.
If the humidity of the interior walls is not only at ground level, but appears at different heights, it may originate as water leaks from the external walls due to obsolete facades, cracked walls or deteriorated joints.
Moisture by condensation.
The humidity due to condensation is due to the humidity produced within the same environment. The main causes are the humidity of the kitchen at the time of cooking, the humidity of the bathroom and even body moisture.
If the rooms are not sufficiently ventilated and ventilated, the humidity will adhere to the interior walls.
Once you have detected the problem and you have found the solution, the moisture or mold stain will remain there until we remove it.
But how can we clean the wall without damaging it or ruining the paint?
This is where our help arrives, so that you can leave the wall in your own condition and look like new again.
Take note of these homemade tricks to clean the walls with dark spots of moisture.
Solution 1:
Remove most of the mold with a sponge soaked in white vinegar.
In a spray bottle, dilute 300ml of white vinegar with 200ml of water.
Spray on areas with moisture stains.
Leave on for several hours and then rub with a clean cloth.
If necessary, repeat the operation.
It is not necessary to rinse, because the vinegar is diluted quickly, but in case the smell is too strong, you can add a few drops of the essential oil of your preference (preferably citrus) to the solution.
Solution 2:
Prepare a solution with 6g of caustic soda in 1 liter of water.
Rub with this mixture the areas with spots.
Leave on all night and the next day, rub with a clean and dry cloth.
You can use the same procedure, but mixing 250ml of bleach (bleach) in a bucket with water.
Depending on the amount of humidity and the deterioration of the walls, you may need to repeat this procedure more than once.
If you use these materials, protect your eyes, mouth, nose and hands and ventilate the environments well.

Another visible place in which the humidity is usually installed with the consequent spots, are the ceramic and tile joints. The humidity of bathrooms and kitchen, usually cause these dark spots of mold.
Let's see a solution to this highly unsightly problem.

Solution 4:

Determine precisely the origin of the mold: humidity, poor ventilation, water leaks, underground filtrations, etc.
Ventilate every room in your house every day to prevent mold from settling.
Check that the air that enters is sufficient. A more ventilated room will be much more sensitive to the proliferation of mold. The rooms should be ventilated at least for half an hour.
In case the humidity does not disappear, you will have to consult a professional.
Use a dehumidifier, if necessary.
