Black mold is not necessarily always black. Usually it will be a greenish-black, but it can also be white, brown, or even yellow. It can also look fuzzy or velvety or can even appear leathery or glassy. It can also be one big stain, or it can come in patches.
Starting Black Mold In Bathroom
Mold grows best on wood, but can also grow on paper products, ceiling tiles, and carpet. Things like nylon or mesh are usually immune to mold, though. You may want to check for other things when looking for black mold, such as yellow discoloration or peeling of walls or wallpaper. The bathroom is a favorite spot for black mold to grow, so check for any black growths in between the tiles on your bathroom floor.
