How To Remove Stains On The Wall Without Damaging The Tincture?

For walls with ordinary paint, apply a few drops of neutral detergent with a damp cloth or sponge. The application should be slow, with no force when rubbing.
It is essential not to use solvents, removers, or multipurpose cleaners. It is also not advisable to remove the dirt at once, just wiping, as it can worsen the stains on the wall.
And in the case of washable paints?
Some brands work with washable paints such as Coral. However, the fact that ink is washable does not mean that no cleaner will damage your paint. Washable paints can also be damaged by using solvents, acids, bleaches, removers, alcohol or abrasive sponges to remove stains. It is therefore recommended to use a sponge or soft cloth and neutral detergent. The difference is that, in the case of washable paints, there is less possibility of fading.
