How to Clean Walls With Flat Paint

Remove dust

The first step in cleaning walls with flat paint is to remove any dust. Vacuum the wall with the brush attachment or simply wipe down the entire wall with a dry microfiber cloth. “Disposable microfiber dusters or washable microfiber dusters are my go-to for dusting walls,” says Brewster. “They trap dirt instead of pushing it around and remove it easily from surfaces as it attaches to the duster fibers.”

To reach the top of the walls, you’ll have to bring out the ladder or attach a microfiber cloth to the end of an extendable mop.
