What Causes Black Stains On Walls?
Black stains on walls can be caused by a variety of factors, including mold, mildew, smoke or soot damage, water damage, or even insect infestations. Mold and mildew thrive in damp and humid environments, while smoke and soot can accumulate on walls from smoking, candles, or other sources of combustion. Water damage can lead to discoloration and staining, especially if left untreated. Insect infestations, such as carpet beetles or cockroaches, can leave behind dark spots and stains on walls. It is important to identify the underlying cause of black stains on walls in order to determine the best course of action for removal and prevention in the future.
