Paint Care

Guide to Washing Your Walls Without Damaging the Paint

Whether you’re managing a high-traffic retail space or keeping a busy household in order, your walls take a beating. From handprints in the hallway to dust on the exterior siding, clean walls are the secret to making a property look well-maintained. However a “clean” wall can quickly become a “damaged” wall if you use the wrong chemicals. We recommend a “gentle-first” approach to protect your high-performance coatings and keep your finishes looking like new. 

Interior Walls: The “Soap & Water” Standard

Most people reach for heavy-duty cleaners first, but for both commercial and residential interiors, simple is best. 

• The Tools: Use a soft sponge or a microfiber cloth. Avoid abrasive pads or “magic” sponges, as these act like fine sandpaper and can strip the sheen (especially on Eggshell or Flat finishes).
• The Solution: A few drops of mild dish soap in a gallon of warm water.
• Residential Tip: For scuffs or “kid-made” art (like crayon), try a paste of baking soda and water first. It provides just enough grit to lift the stain without the harshness of a chemical solvent.
• Commercial Tip: In office environments, focus on “touch points” like light switches and door frames where oils from hands accumulate. 

Cleaning Textured Walls

Textured surfaces (knockdown, orange peel, or popcorn) are dust magnets and can be tricky to clean without snagging the paint. 

• Dust First: Use a vacuum with a soft brush attachment to remove loose particles. 
• Blot, Don’t Scrub: When washing, use a blotting or stippling motion. If you scrub in circles, you risk chipping the peaks of the texture, which creates a patchy look that is difficult to repair. 

Exterior Maintenance: Protecting Your Curb Appeal

Maintaining your building’s exterior isn’t just about looks, it’s about asset protection. Removing salt, pollen, and dirt prevents the paint film from breaking down prematurely. 

• Low-Pressure Rinsing: A standard garden hose is usually all you need for exterior wall care.
• The Danger of Power Washing: Many times DIY homeowners and business owners accidentally carve lines into their siding or force water behind the board using high-pressure sprayers. If you must use a power washer keep it on the lowest setting or hire a professional like Lamb Painting for a soft wash!

Pro-Tip from Lamb Painting: Before cleaning the entire wall, always do a spot test in an inconspicuous area (like behind a door or near the baseboard) to ensure your cleaning solution doesn’t change the color or sheen of the paint
