Cleaning your walls before painting is super important – it can be the difference between paint that lasts and paint that peels off too soon. In fact, most paint jobs that fail happen because people skip this key first step.
According to Jeff Spillane, senior manager at Benjamin Moore Paints, “A clean surface is just as important as quality paint when it comes to a lasting finish.”
Getting your walls ready doesn’t have to be complicated. Think of it like washing your car before getting it painted – you want a clean surface so the new paint sticks well. Whether you’re dealing with everyday dust or kitchen grease, taking time to clean your walls properly will help your paint job look great and last longer.
Let’s make sure your next paint project turns out awesome by learning the right way to get those walls clean and ready for paint. Just like you wouldn’t put clean clothes on without taking a shower first, your walls need to be totally clean before they get their new coat of paint.

Things to Do When Cleaning Walls Before Painting
Cleaning walls before painting is a methodical process that requires the right tools and techniques to guarantee the best possible surface for paint adhesion. A thorough cleaning removes dirt, grime, and oils that could prevent paint from properly bonding to the wall, while also eliminating any residual spider webs or dust that might create texture issues in the final coat.
- Dry dust first – Use an extendable duster or microfiber cloth to remove loose debris and cobwebs.
- Prepare cleaning solution – Mix warm water with mild dish soap in a spray bottle for general cleaning.
- Section the wall – Work in manageable 5-10 foot sections to prevent cleaner from dripping.
- Apply cleaner – Use a flat microfiber mop to gently wash the wall surface.
- Tackle stains – Treat stubborn marks with foaming wall cleaner and targeted scrubbing.
- Dry thoroughly – Wipe walls with clean, dry towels to prevent water damage to existing paint.
- Check surface – Inspect walls for any missed spots or remaining stains.
- Allow drying time – Let walls dry completely before beginning any painting work.
Things to Avoid When Cleaning Walls Before Painting
Before painting, proper wall cleaning is essential, but certain practices can compromise both the cleaning process and the wall’s integrity. Taking shortcuts or using improper cleaning methods can lead to damaged surfaces, uneven paint absorption, and poor final results, potentially requiring extensive repairs or complete refinishing of the walls.
- Excessive moisture – Using too much water can saturate the wall surface, leading to bubbling, peeling, or water damage.
- Aggressive scrubbing – Harsh scrubbing motions can create burnished spots and damage the existing surface.
- Chemical cleaners – Strong or abrasive cleaning solutions can etch the surface and prevent proper paint adhesion.
- Direct sunlight cleaning – Cleaning walls in direct sun causes uneven drying and can leave stubborn streaks.
- Contaminated tools – Using dirty cleaning materials spreads grime instead of removing it.
- Hot water – Temperature extremes can affect surface integrity and cause expansion/contraction issues.
- Circular motions – Cleaning in circles can create noticeable swirl marks that show through new paint.
- Skip drying time – Not allowing walls to dry completely before painting leads to adhesion problems and bubbling.
