How to Clean a Wall Before Painting: Step by Step

Before cleaning your walls, remove all pictures, mirrors, and other decor. Also, take down curtains and pull furniture out of the way.

If you’re wondering what to use to clean your wall before painting, just use plain water. Unless your wall is filthy or has sticky residue, dusting and then wiping with water is sufficient.

Here’s what you’ll need to clean the wall before painting:

  • Duster or vacuum with hose attachment
  • Soft sponge
  • Towel

Step 1: Dust the Walls

Dust the entire wall using a vacuum with a hose attachment or a handheld duster. Pay special attention to corners where cobwebs develop. Dust from top to bottom.

Step 2: Wash the Walls

Dampen a soft sponge with water and wash the walls starting in one corner of the room and making your way around. Wash the walls from top to bottom. Rewet and rinse out your sponge as needed. It should be damp but never soaking wet.

Add a little dish soap to your sponge if you have a sticky spot on the wall or an area that won’t come clean. Rinse the sponge well afterward.

Step 3: Let the Wall Dry and Then Paint

Wipe down all the walls with a towel to soak up excess moisture. Then wait until the wall is fully dry before you paint.

Drying can take between 20 minutes to 2 hours, depending on your home’s temperature, humidity level, and how wet you got the wall.
