Even the most beautiful paint job can lose its appeal when walls start collecting fingerprints, dust, or stains. Cleaning painted walls is essential for keeping your home fresh and well-maintained—but improper cleaning can dull finishes or cause paint to peel. Here’s how to clean painted walls safely and effectively, while preserving their colour and sheen.
Can you wash painted walls without ruining the paint?
Yes—but the method depends on your paint finish and paint type. Durable finishes like satin, semi-gloss, and gloss can be cleaned easily with mild soap and water. Flat or matte finishes, however, require gentler care to avoid removing pigment or creating shiny spots.
Always start with the least aggressive method first: dusting, followed by spot cleaning, and finally gentle washing for tougher stains.
How often should you clean your walls?
For most homes, walls should be cleaned once or twice a year to remove dust and maintain the paint’s appearance. High-traffic areas such as hallways, kitchens, and bathrooms may need more frequent touch-ups every few months.
What’s the safest way to dust painted walls?
Before washing, always remove dust and cobwebs. Use:
- A microfiber cloth or electrostatic duster for smooth walls
- A soft-bristled broom wrapped with a clean towel for hard-to-reach areas
- A vacuum with a brush attachment for textured walls or ceilings
This step prevents dirt from turning into grime when mixed with water during washing.
What cleaning solution should I use on painted walls?
Start with the mildest option possible:
- Mix a few drops of mild dish soap in a bucket of warm water.
- For tougher stains, add a tablespoon of baking soda to the mix.
- Avoid harsh chemicals, ammonia, or degreasers—they can damage paint finishes.

How should I wash the walls?
-
Test a small area first: Choose an inconspicuous corner to ensure the colour doesn’t fade.
-
Work from top to bottom: This prevents streaks and drips.
-
Use a soft sponge or cloth: Dip it in the soapy solution, wring it out well, and wipe gently in circular motions.
-
Rinse with clean water: Use a second sponge to remove soap residue.
-
Dry the wall: Wipe with a clean, dry towel to avoid water marks.
Never soak your walls—too much moisture can cause bubbling or peeling, especially in older paint jobs.
What if the walls have stains or marks?
-
Scuff marks: Gently rub with a damp sponge and a pinch of baking soda.
-
Grease stains (in kitchens): Use a diluted mix of dish soap and warm water.
- Crayon or ink: Apply a small amount of vinegar or rubbing alcohol to a cotton cloth—test first to ensure it doesn’t lift the paint.
Always use light pressure; scrubbing too hard can damage the surface sheen.
How do I clean flat or matte paint walls safely?
Flat and matte finishes are more delicate. For these surfaces:
- Avoid excessive water.
- Use a damp (not wet) sponge.
- Gently dab rather than scrub.
- Touch up paint afterward if needed.
For future repaints, consider washable matte paints from Randall’s for improved cleanability without shine.
Should you clean freshly painted walls?
Wait at least two weeks before cleaning newly painted walls. This allows the paint to cure fully and harden, ensuring you don’t remove or dull the finish prematurely.
Can professional painters help with paint touch-ups after cleaning damage?
Absolutely. If cleaning reveals faded areas, scuffs, or spots needing touch-up, a professional can restore the surface quickly. Visit our Services Pageor complete a Painter Order Formto get connected with experienced painters who can match colours perfectly.
When should you consider repainting instead of cleaning?
If your walls show signs of permanent discoloration, bubbling, or peeling even after cleaning, it might be time for a fresh coat. Repainting not only revives your space but also provides better washability with modern paint formulas.
