How to Clean Your Painted Walls

There’s an area of your home that’s easy to forget to clean: your walls. Fingerprints, kid messes, spills and pet grime all accumulate on walls. Especially in high-touch areas like doorways, near switch plates and the lower half of walls. Here’s how to clean them without messing up your paint job.

Tools and Materials

How to Clean Your Painted Walls

Before you clean, it’s important to understand what type of paint finish is on your walls. Matte or flat paint, unless it’s scrubbable, is hard to clean without compromising the paint job. Newer formulations are easier to clean. Eggshell, satin, semi-gloss and gloss paint are easier to clean. Even so, proceed with the gentlest cleaning methods first and always test a small area of your wall that’s out of the way.

Step 1: Remove Dust From the Wall

Start by thoroughly dusting your walls, moving from the top and working your way down to the baseboards. Toward the top of the wall use the extendable duster to get cobwebs and dust. Once you get to the bottom of the walls vacuum up any fallen dust and pet hair that accumulates around the baseboards.

Step 2: Wipe Down Your Walls

Start by mixing a solution of warm water with a few squirts of dish soap. Take a microfiber cloth and dip it into the soapy solution, then wring out the excess water. Using gentle circular motions and not scrubbing, wipe down a small area being careful not to over wet the wall. Avoid letting water drip down the walls—this means there’s too much water still in the cloth. Using a separate microfiber cloth with just water, rinse the area you cleaned. Then using a dry microfiber cloth, remove any excess water from the wall. 

Microfiber cloths provide a gentle, yet effective cleaning material that helps pull dirt and grime without damaging the wall paint. You don’t need to wipe down every square foot of interior walls, just focus on high-touch areas that look dirty. Pay special attention to switch plates and doorways.

Step 3: Handling Tough Stains

Sometimes stubborn stains require a tougher approach. A damp melamine foam sponge can be used to wash stubborn dirt or even kid’s messes like colored pencil off a wall. Be sure to test your paint’s durability in a small, unseen spot before using. After you wipe an area with the sponge, wipe it down again with a damp microfiber cloth and dry with another clean cloth.

How Often Should You Clean Your Walls?

One of the best ways to keep your walls clean is regular maintenance. Quickly cleaning up messes or spills when they happen cuts down on stains. For a deeper clean, consider checking your walls seasonally to make sure they’re not starting to look dingy. Obviously, white or light color walls show more, so consider your lifestyle before choosing a paint color.
