To clean painted walls, choose the best cleaning method based on the type of wall finish. Flat, eggshell or stain finishes is less durable and more likely to rub off. Try not to scrub too hard or wash with too abrasive a cleaner. Avoid harsh chemicals and use a mix of mild detergent and water.
The best solution for cleaning walls is mild soap and warm water, as the soap will work hard to remove grime without harming the painted surfaces. If you have tougher stains or built-on dirt, you can scrub away these imperfections using a mix of baking soda and water, which acts as a natural, mild stain remover.
Many wall paint finishes are less durable than those typically used for window trim, doors, and baseboards. Never use harsh chemicals or commercial degreasers on walls with flat, satin, and eggshell finishes. Wash these walls with a soft sponge dampened with liquid dish soap and water.
Glass cleaner's abrasive nature can gradually degrade paint on various surfaces, whether it's your home's walls, the exterior of your car, or painted furniture. It's best to use cleaning products specifically formulated for painted surfaces to safeguard your paint's longevity and appearance.
To clean walls gently, according to Carpenter, you'll need a mild detergent like Dawn dish soap, a Magic eraser, a bucket, water, sponges, and micro-fiber cloths for wiping down walls as well as drying them.
Fill a bucket with warm water and add a small amount of mild dish soap. This soapy solution works well for most paint finishes like latex paint, eggshell finishes, and even semi-gloss. Avoid using harsh chemicals or abrasive cleaners, especially on delicate finishes like flat paint or oil-based painted walls.
An opened (and resealed) can of paint typically lasts for less time because of bacteria that can grow in the paint. Bacteria need certain conditions to grow, including darkness, moisture, and heat. All those conditions occur inside a closed paint can in your garage, shed, or basement.

Or anything overly abrasive for that matter. Magic erasers are particularly rough on painted walls because they are chemically abrasive. Even the most durable finishes will come off if you scrub them with a magic eraser. A sponge or damp cloth is more than sufficient for cleaning painted walls.
A few small nail holes are wear and tear; large holes in the walls constitute damage. Fading or yellowing of paint is wear and tear; large stains on the walls and ripped wallpaper is damage.
Construction imperfections may also be a contributing factor. For instance, improperly taped drywall joints or shrinkage in concrete foundation walls can lead to cracks. Further, leaks in the roof, plumbing or poor ventilation can lead to moisture buildup in walls, causing cracks.
You can tell paint has gone bad by the smell and texture. A rancid or sour-smelling paint means your paint has gone bad. In particular, the smell of bad paint is similar to sour milk. Other indicators of expired paint include a lumpy or chunky paint consistency.
