If moisture is causing mold in the corners of your walls, you can eliminate it using this method

Excess humidity in rooms leads to the  formation of condensation and mold , which appears as  black spots.

There are many places where mold can be found, but  the corners of walls  are where it most frequently occurs.

For this reason, today we are going to see together some  homemade and natural solutions  to eliminate mold from wall corners in a quick and easy way!

Sodium bicarbonate

The first tip is to use  baking soda,  which has very effective cleaning and whitening properties and is particularly suitable for white walls.

All you have to do is slowly mix  the baking soda with water,  until you obtain 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, use  a sponge or brush  to remove the stain and you will see that everything will be clean!

Alternatively, you can also  fill a bowl with warm water and  then add  2 tablespoons of baking soda . Next, dip a cloth into the mixture, wring it out well and dab it onto the stain. To enhance its action, you can also add  a few drops of tea tree oil  with baking soda!


Another very effective ingredient to use in case of mold 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 lukewarm water and a few drops of vinegar, dab it (without rubbing)  very delicately  on all the mold stain present in the corners of your walls. After that, let it dry  and that’s it!

Citric acid

As an alternative to vinegar, you can also use  citric acid,  which is an ecological compound derived from citrus fruits, known for its degreasing and especially anti-limescale properties. Unsurprisingly, it’s  a godsend for cleaning all your devices from top to bottom!

Dissolve about  150 grams of citric acid in 1 liter of water , then mix and pour everything into a spray bottle. At this point,  spray the mixture onto the mold stain  and dab with a cloth until it is permanently removed.

Lemon juice

After vinegar, bicarbonate and citric acid, how could we not  mention lemon,  with its multiple properties that help us  in ecological household cleaning? As if that wasn’t enough, it  also provides a fresh scent!

In  2 cups of lukewarm water , pour  two tablespoons of filtered lemon juice  and pour everything into a bottle. After that, spray  the mixture on the stain  and let it sit for a while so that it can work and melt the mold.

Once the necessary time has elapsed, rinse with a  microfiber cloth soaked in water and dab lightly.

Hydrogen peroxide

If the  mold stain is very stubborn  and difficult to come off, then you can use  hydrogen peroxide to disinfect and whiten!

Simply  dampen a microfiber cloth,  pour a little hydrogen peroxide on it , then place the cloth over the affected area and let it sit for a while. Alternatively, it is also possible to wet  cotton discs or balls  with hydrogen peroxide and dab them on the “black” corners.

NB:  We remind you that this method should only be used on white walls, otherwise you will stain them irreversibly.

Coarse salt

Now let’s see together how to use  salt  which, although not able to directly eliminate black mold stains , can nevertheless prevent their formation.

Coarse  salt,  in fact, is used to  create a natural dehumidifier , capable of countering the formation of humidity in the home. Add a little salt to  a jar  and place it in areas affected by mold or in places where it tends to form: goodbye mold!


I remind you to start by testing these methods in a hidden corner to make sure you don’t damage the surfaces. In the event of large mold stains, expert advice is required.
