How to wash painted walls

A new wall is not a washable wall yet

The film you can touch without transferring color is still soft. Washing it, or even taping it, can burnish, streak or lift it. Two Benjamin Moore pages and one Sherwin-Williams FAQ do not print the same wait, and it is more honest to show both than to average them.

• Sherwin-Williams’ maintenance FAQ: wait at least two weeks before washing a freshly painted wall, so the dry film reaches its washability. Avoid abrasive or harsh chemical cleaners. Test any cleaner in a hidden spot first.
• Benjamin Moore’s burnishing note: for maximum durability, wait at least two weeks after painting before washing. Clean with non-abrasive cleansers, a soft cloth or sponge, and rinse with clean water.
• Benjamin Moore’s page on freshly painted walls and cabinets: wait until the paint is fully cured, and at minimum allow 30 days, before cleaning. If you must spot-clean sooner, do it carefully. They tell you to avoid abrasive sponges such as Magic Erasers, scouring pads, and harsh cleaners such as bleach, ammonia or alcohol.
• A specific product can be more precise than either article. Benjamin Moore’s Regal Select eggshell data sheet says that paint can be washed after two weeks. If your can or sheet names a time, use it. If it does not, the 30-day article is the conservative reading of the same company’s advice.

Cure, as distinct from dry-to-touch and recoat, is dry time versus cure time. Nothing in the washing guidance shortens a cabinet enamel that needs a week before shelves go back into service.

Sheen decides how hard you may scrub

Benjamin Moore’s cleaning steps start with the finish you have, not the stain you are chasing. Higher gloss is easier to clean. They name satin, pearl, semi-gloss and high gloss as the more forgiving end, and flat, matte and eggshell as finishes that need a lighter hand. The same company’s sheen guide says stains are harder to remove from low-sheen paint and that repeated rubbing can burnish it, which is the shiny spot that does not match the wall around it. Their burnishing note says to put higher sheen, eggshell through semi-gloss, in high-traffic areas, and to avoid flat where people and furniture rub.

If you are choosing paint now and you know the wall will be washed, that is an argument for eggshell or satin in a hallway or a child’s room, and for satin or semi-gloss in a kitchen, which is the same map as sheen by room. If the wall is already flat, change your technique, not the laws of the finish. You will not scrub a flat wall into the washability of a semi-gloss. You will scrub it into a shiny patch. Background on why sheen changes both cleaning and appearance is the sheen guide.

The order of attack

Benjamin Moore’s wall-cleaning steps, and Sherwin-Williams’ maintenance steps, line up closely. Combined, the sequence is:

1. Dust first. Use the brush attachment on a vacuum, or a microfiber cloth, so you are not making mud out of loose dust.
2. Try water alone. Benjamin Moore calls plain water one of the best cleaners. Use a large non-abrasive sponge and warm water, and rub lightly. A lot of scuffs never need soap.
3. Then mild dish soap, in a second bucket, if water failed. Wear gloves if your skin objects. Work small areas. Rub in a circle, gently. Let the soap do the work.
4. Start at the bottom and work up. Both companies say this. Dirty water running down a dry, dusty wall makes streaks that are harder to remove than the original mark. Cleaning upward means the drips run over a part you are about to wash.
5. Rinse as you go with a sponge and clean water from the second bucket. Sherwin-Williams adds: do not let a concentrated cleaner dry on the surface. Mix it the way the cleaner’s own label says, wash, and rinse thoroughly.
6. Dry with a soft cloth so leftover moisture does not sit in a cool corner and invite mildew. That last risk is why bathroom washing and bathroom ventilation belong together: bathroom moisture and mildew.

Cleaners they tell you not to use

Benjamin Moore says never to use glass cleaner or a heavy-duty household spray on a painted wall. Those products contain solvents that can damage the finish. On fresh paint they also say to skip bleach, ammonia and alcohol. Sherwin-Williams says that if you are cleaning waterborne paint, avoid ammoniated cleaners, and that mild soapy water generally suffices. Both say to test in an inconspicuous place before you do a whole wall. A spot behind a door is the test, not the middle of the wall above the sofa.

For stains that survive soap, Benjamin Moore lists gentler household cleaners as options, not as a mixture: an all-purpose cleaner such as Method or Fantastik, Simple Green, or a plant-derived cleaner such as Mrs. Meyer’s. Pick one, follow that bottle, and do not stack products. They still want the same bottom-up, light-pressure technique. If a stain does not move under that regime, it may be in the film, not on it. A marker that bled into flat paint often will not wipe out. That is a touch-up or a repaint, not a harder scrub. Touch-ups that do not flash are flashing and lap marks.

Cabinets and trim are less forgiving

Benjamin Moore’s fresh-paint cleaning page separates cabinets from walls. Cabinets take more contact, so they say to dab rather than scrub, to test a hidden spot, and to wipe spills soon with a damp microfiber cloth and mild soap. Do not hang a wet towel on a door. Standing water softens a film that is still curing, and it marks a film that is fully cured. Their burnishing note also says to notice where furniture rubs, because the shine spot is often mechanical wear, not dirt. Felt pads and a slightly higher sheen prevent more of those spots than any cleaner removes.

Trim in semi-gloss will tolerate more washing than a flat wall beside it. Use that difference. Do not bring the trim technique, or the trim cleaner, across the whole wall just because it worked on the baseboard.

When washing is the wrong job

Grease on a kitchen wall that you are about to repaint is a prep problem, not a maintenance problem. Benjamin Moore’s prep page wants a grease-cutting detergent and a clean-water rinse, then a full dry, before any new paint. Washing a wall you intend to paint next weekend can be the first prep step, as long as the wall is dry again before you tape or prime. That sequence is how to prep walls.

Mold is not a soap-scuff. The EPA says to scrub mold on hard surfaces with detergent and water, dry the surface, and fix the water problem. Painting or caulking over mold is a listed mistake, because the paint peels. If the growth covers more than about 10 square feet, their mold guide points you to a larger remediation practice rather than a sponge. Do not treat a mold wash as ordinary wall cleaning, and do not mix bleach into a casual bucket because a website said so. Use a product labeled for the job, ventilate, and keep the solution off skin and eyes.

Lead dust is the other exception. In a pre-1978 house, the EPA’s ordinary cleaning advice is a damp wipe of hard surfaces, not dry sweeping and not scouring pads that can grind paint. If the paint is damaged, the job may be lead-safe repair rather than washing. See lead-safe painting.

FAQ

How soon can I wash a wall after painting?

Sherwin-Williams says at least two weeks. Benjamin Moore’s burnishing guidance also says two weeks, while its page on freshly painted walls and cabinets says to wait until the paint is cured and at least 30 days. If your product’s data sheet names a time, use that. Otherwise wait the longer period.

Why do flat walls get shiny where I clean them?

That is burnishing. Benjamin Moore notes that low sheens mark when they are rubbed, and that higher sheens tolerate cleaning better. Lighten your pressure, or plan on a higher sheen where the wall gets washed often.

Should I wash from the top or the bottom?

From the bottom up. Both Benjamin Moore and Sherwin-Williams say dirty water running down a dry wall leaves streaks that are hard to remove.

Can I use a magic eraser or glass cleaner?

Benjamin Moore says no to glass cleaner and to heavy solvent sprays on painted walls, and no to abrasive sponges such as Magic Erasers, scouring pads, bleach, ammonia or alcohol on fresh paint. Sherwin-Williams says to avoid ammoniated cleaners on waterborne paint.

What if the mark will not come off?

Stop before you burnish a hole in the sheen. A stain that has soaked into flat paint usually needs a touch-up or a new coat, not more pressure. Let the wall dry and look at it in raking light before you decide.
