Excess moisture in rooms results in the formation of condensation and mold that takes the form of black spots. The places where we can find mold are numerous, however, the corners of walls are the ones on which it most frequently settles. Therefore, today we will look together at some homemade and natural solutions to remove mold from wall corners quickly and easily!

Baking soda

The first remedy is to use baking soda, which boasts very effective cleaning and whitening properties and is especially suitable for white walls. All you will need to do, then, is to mix the baking soda with water until you get a sort of paste-like mixture. At this point, apply it to the stain, leave it on for a while and wait for it to dry. Finally, wipe it off with a small sponge or brush to send the stain away, and you will see that everything is clean!

Alternatively, you can also fill a bowl with warm water and then add 2 tablespoons of baking soda. After that, soak a cloth in the mixture, wring it out well and dab it on the stain. To enhance the action, you can also include a few drops of tea tree oil along with the baking soda!


Another very effective ingredient to use in case of mildew is vinegar, which is able to remove stains and degrease. We remind you, in fact, that it is generally used to wash the walls of the house! So, dip a microfiber cloth in a bowl containing warm water and a few drops of vinegar, dab it (without rubbing) very gently on all the mold stain present in the corners of your walls. After that, let it dry and you’re done!

Citric acid

As an alternative to vinegar, you can also use citric acid, which is an environmentally friendly compound derived from citrus fruits and known for its degreasing and especially anti-scale properties. Not surprisingly, it is a godsend for thoroughly cleaning household appliances! So, dissolve about 1/3 lb. of citric acid in 1 quart of water, after which, mix and decant it into a spray bottle. At this point, spray the mixture on the mold stain and dab with a cloth until it is permanently removed.

Lemon juice

After vinegar, baking soda and citric acid, how could lemon, which boasts multiple properties that come to our rescue in eco-friendly household cleaning, be missing from the roll call? As if that were not enough, it is also able to bring a fresh scent! Then, in 2 cups of lukewarm water, pour two tablespoons of filtered lemon juice and decant it into a steamer. After that, spray the mixture on the stain and leave it on for a while so that it can act and dissolve the mildew. After the necessary time has elapsed, rinse with a microfiber cloth moistened with water while dabbing lightly.

Hydrogen peroxide

If the mold stain is very stubborn and struggling to go away, then you can use hydrogen peroxide, which can disinfect and bleach! All you need to do is dampen a microfiber cloth, pour some hydrogen peroxide on it, then place the cloth on the affected area and leave it for a while. Alternatively, you can also wet some cotton pads or absorbent cotton balls with hydrogen peroxide and dab them on the “black” corners.

N.B. Please note that this method is to be used only on white walls otherwise you can stain them irreversibly.

Rock salt

Now let’s see together how to use salt, which, although not effective in directly removing black mold stains, may be able, however, to prevent its formation. In fact, coarse salt is used to create a natural dehumidifier that can counteract the formation of moisture in the home. Add, then, salt to a jar and place it, then, in the areas where there is mold or in the places where it tends to create itself: goodbye mold!


I remind you to use these methods first on in a hidden nook to make sure you don’t damage surfaces. In case of large mold stains, you should consult an expert on the matter.
