Wall stains range from scuffs and grease to smoke and water marks, and the cause decides which cleaner belongs. Most surface marks come off with a wash, and if the wall comes clean, repainting may not be needed at all. Penetrating stains are the hard ones, and oil, grease, tar and solvent-based marker call for a solvent-based cleaner, while water and smoke stains need a water-based one.
Marks on walls usually come off with a damp cloth before anything else, so try that first. If vaping has left a film, use a water-based cleaner, since a scouring cleanser can dull the paint. Steam stains on bathroom walls are easier to avoid than remove, so dry the area after each shower.

Step by step
Step 1 of 7
Dust the wall first
Run the dust-brush attachment of a vacuum over the wall, or wipe it with a dry cloth. Loose dust turns into a smear the moment it gets wet, so clear it all before you add any water.
Careful. Wait if the paint is less than two weeks old; wetting it sooner can alter or damage the finish.
Step 2 of 7
Test on a hidden spot
Pick an inconspicuous spot, such as a corner or an area behind furniture, and try your cleaner and technique there first. You're in the clear if the paint still looks bright and no water marks remain once it dries.
Tip. Give the test spot its full drying time before you judge it.
Step 3 of 7
Wipe with plain warm water
Wring a large, non-abrasive sponge out thoroughly, then wipe the stain with plain warm water. Plain water is the first cleaner to try, and it often lifts a light mark on its own.
Tip. Rinse the sponge often so you aren't spreading the dirt around.
Careful. Don't over-wet or press hard on matte paint; it can damage it.
Step 4 of 7
Add a little mild detergent
If plain water doesn't lift the mark, add a little mild dish detergent to warm water. Rub gently in a circular motion, working from the bottom of the wall up, and rinse as you go.
Step 5 of 7
Lift scuffs with baking soda paste
For a scuff or spot, mix baking soda with water into a paste and rub it on gently. Rinse with a sponge, then dry the area with a soft cloth.
Step 6 of 7
Treat grease with dish soap
Grease splatters respond to grease-cutting dish soap in warm water, so start there. For tougher marks, use one all-purpose cleaner on its own, and let it work without scrubbing hard.
Careful. Use one cleaner at a time; never combine products.
Step 7 of 7
Dry the wall thoroughly
Dry the whole wall well once it's clean, so no moisture is left sitting in the paint. Leftover damp is what leads to moisture damage or mildew.
Tip. Check the corners and the bottom edge, where water tends to collect.

How to tell it's working
The stain is lifting when the paint looks as bright as the surrounding wall and the sponge comes away clean. If the paint looks dull or you see water marks, stop, let the wall dry fully and reassess before doing anything else.
What changes for yours
Adjust for your walls
Smoke, vaping, and drug-related residue
Smoke and vaping residue usually shows as a yellowish or sticky film rather than a single spot, so expect to wipe the wall more than once. Work in small sections with plain warm water and let each one dry before you judge it.
If the film survives the steps, move to the water-based cleaning solution for smoke stains in the set-in options, tested on a small area first. Drug-related marks are cleaned the same way, and any mark that reappears after drying needs a closer look at the moisture.
Bathroom walls
Bathroom walls get splashes and soap film, so the marks are often water staining rather than dirt. Start with plain warm water on a well-wrung sponge, and keep the sponge damp rather than wet.
Open a window or run the fan while the wall dries, since trapped moisture is what leads to mildew. Dry the wall well afterward, and check the corners where water sits longest.
Pest and insect marks
Insect marks are usually smears or spots that have dried onto the paint. Lift them with plain warm water first, and move to the mild detergent only if the mark is still there.
Dust off any dried residue before you wet it, because wet dust smears. Test on a hidden spot first, since a dried mark can take longer to soften.
White walls
White walls show every mark, so a stain that looks small can still be obvious after cleaning. Work from the edges of the stain inward, and rinse the sponge often so you don't spread dirt across the paint.
Check the wall in daylight once it's dry, since streaks often only show as the paint dries. If a faint shadow remains, go back over just that patch with the water step, not a stronger cleaner.
Drywall, plaster, and textured walls
Keep the water light on drywall and plaster, because soaking can soften the surface and leave a dull patch. Wring the sponge until it barely drips, and wipe in short strokes.
On textured walls, dust thoroughly before you wipe, since dust settles into the texture and smears when wet. Let each section dry before you judge it, and avoid pressing into the texture.
Wallpaper
Wallpaper needs a lighter touch than painted walls, and it can't take much water. If you can't tell whether it's washable, dust it and don't wet it, because some textured wallpapers cannot be washed at all.
Use no abrasive cleaners, even on washable paper, and keep any cloth barely damp. For grasscloth, professional cleaning may be necessary, so ask before you try to clean it yourself.
Kitchen walls
Kitchen walls mostly collect grease splatters, so the grease treatment matters more here than the general wipe-down. Start with plain warm water to lift the surface film, then move to the grease step.
Give a stubborn grease spot a second pass with the same grease step rather than switching to a stronger cleaner. Let the wall dry fully between passes.
Old, dried or set-in stains
An old stain has had time to bond with the paint, so start with the gentle steps and give them a second pass before anything stronger. Wash first, because if the stain comes clean, repainting may not be needed at all.
If a stain has dried, rewet it lightly with warm water and let it soften before you rub. Once the wall is washed and dried, look at it in good light before you decide on anything else.
For a penetrating interior stain, try a mild detergent first, then an abrasive cleaner with water, tested on a small area first. Use a solvent-based cleaning solution for oil, grease, tar and solvent-based marker stains, and a water-based one for water and smoke stains. Then seal the stain with a stain-blocking primer, and if it still shows, repaint over the primer.

Do home remedies work on walls?
Many home remedies are made for fabric, counters or floors, so most of them don't belong on a painted wall. Dish soap and baking soda are the two worth using on a painted wall, so skip the rest.

What makes it worse
Mistakes to avoid
Don't reach for glass cleaner or spray cleaners
Glass cleaner and heavy-duty household spray cleaners, including all-purpose sprays, can damage the finish of a painted wall, even when they seem gentle. Keep them off the wall and stick to water and mild detergent instead.
Don't keep rubbing an old stain
Repeated rubbing on the same spot can wear the finish before the stain lifts. If a stain survives the steps, move on to the set-in options rather than scrubbing harder.
Don't paint over a stain before washing it
Washing first can make repainting unnecessary, so paint should be the last resort rather than the first. Covering a dirty mark too early means you have to deal with it again later.
Troubleshooting
If the stain is still there
Pick what you're seeing:
A water ring or streak appeared after washing.
The sponge was likely too wet. Rinse the whole area lightly with a well-wrung sponge, blending outward past the ring, and dry it right away with a soft cloth.
A dark spot in a damp room won't wash off.
Dab a little bleach on it to tell mildew from dirt: if it bleaches away, it is probably mildew. Treat mildew with 1 part liquid bleach to 3 parts water, scrub, leave 10 minutes, and rinse well.
A shiny or dull patch remains where the stain was.
The finish has been worn by rubbing, and more cleaning won't fix it. Touch up with paint of the same color and sheen, applied by roller or brush to match the original.
The stain keeps bleeding back through after washing.
It has penetrated the paint. Clean it with the right type of solution, then seal it with a stain-blocking primer before repainting.
When to call a professional
You don't need a professional for ordinary painted walls. If the stain survives the steps and the set-in options, ask the store staff at the paint counter where you bought the paint. For grasscloth wallpaper, professional cleaning may be necessary.
Questions
Can old, set-in stains come out of a wall?
Often, yes, if you wash first and give the stain a second pass before reaching for anything stronger. If it stays, the set-in options come next, starting with a mild detergent, and each one should be tested on a small area first. A stain that has fully soaked into the paint may never lift completely, and in that case covering it is the practical fix.
Is it better to paint over a stain than clean it?
Clean it first, because a stain that comes out means you may not need to repaint at all. If it won't lift, seal it with a stain-blocking primer before the topcoat, and for water stains choose a primer made for that job.
Do stain removers work on painted walls?
Start without one, since plain warm water and a little mild dish detergent handle most marks on painted walls. If you do try another product, test it on a hidden spot first and stop if the paint dulls.
Does a spray product leave a stain on a wall?
It can leave a film or mark, and the cause matters less than the treatment. Start with plain warm water on a well-wrung sponge, then add a little mild dish detergent only if the mark stays.
Why do water stains keep coming back?
Usually moisture is still getting into the wall, or the wall never dried fully after cleaning. Dry the wall thoroughly each time, and check the source of the moisture before you clean it again.
Can a scuff or transferred color come off a wall?
Usually yes, as long as the paint underneath is intact. Use the gentle scuff treatment, rinsing the sponge as you go, and test a hidden spot first if you're unsure of the paint.
