How to Remove Dust from Painted Walls

Move breakables and protect nearby furnishings. Use a stable tool that lets you reach the area safely from the floor; do not overreach or climb furniture. Avoid electrical outlets and switches.

Use a clean microfiber cloth or soft duster and light strokes, working from high areas downward. Shake or replace the cloth as it collects dust so you do not drag grit across the paint.

If dust remains and the paint maker permits it, test a barely damp cloth with a compatible mild cleaner in an inconspicuous spot. Do not saturate the wall or use abrasive pads, strong alkalis or unverified mixtures.

If paint transfers, softens, streaks or flakes, stop and let the area dry. Stains, mould, lead paint concerns and paint damage need a different assessment; routine dusting is not remediation or painting preparation.
