- Dust talcum powder over the grease to soak up what's loose, then brush it off.
- Lift any solid or semi-solid grease with a rounded spoon or dull knife before adding liquid.
- Blot liquid grease with a clean, dry white cloth or paper towel; don't rub.
- Keep heat away from the spot until it's gone, since heat sets stains.
Grease on a painted wall spreads the moment you wipe it, and the paint is usually the weak point in the cleanup. Matte finishes can dull or leave water marks if you press hard or wet them too much, and fresh grease lifts faster than an older shadow that has set into the surface. If the paint is less than two weeks old, leave the wall alone until it has cured, because washing it sooner can change the finish.
Work from the edges of the mark toward the middle so the grease doesn't spread. Yellow grease stains on kitchen walls are the kind to be patient with, so stop rubbing once the wall feels dry. If the mark still shows after two gentle rounds, a scouring cleanser used very lightly, after the soap, is the next thing to try.

6 steps
Step by step
Step 1 of 6
Lift off the solid grease
Use a rounded spoon or dull knife to lift any solid or semi-solid grease off the wall before you add any liquid. Dust talcum powder over what's left, then brush it off thoroughly.
Step 2 of 6
Blot the liquid grease
Press a clean, dry white cloth or white paper towel onto the wet spots to take up the loose grease. Work from the outside edge toward the middle, and switch to a fresh section of cloth as it fills.
Step 3 of 6
Wipe with the soap solution
Mix 1 teaspoon of mild liquid dish soap into 1 cup of warm water. Dip a sponge in the solution, wring it until it's barely damp, and wipe the grease in small sections.
Tip. Wring the sponge well before each pass so the wall stays nearly dry.
Step 4 of 6
Rinse with clear water
Wring a clean sponge out in plain water and wipe over the same section to lift the soap film. Rinse the sponge often, and dry the section with a clean cloth before you move on.
Step 5 of 6
Use a light baking soda paste
If a shadow remains, mix baking soda with a little water into a paste. Rub it gently over the spot with a non-abrasive sponge, then rinse it off with a clean damp sponge.
Tip. Use this only on what's left after the soap solution, not on the whole wall.
Step 6 of 6
Clean the last spots with alcohol
Dampen a corner of a clean white cloth with denatured alcohol and wipe the small stained area only. Turn the cloth often so you lift the grease rather than spread it, then let the spot air dry.
Tip. Pretest the alcohol on a hidden spot first, since it can affect some finishes.
Careful. Denatured alcohol is flammable, so use it in a ventilated room with no flames, pilot lights or sparks nearby.

Best products for grease on walls
Look for a mild degreasing cleaner labeled for painted walls, and skip oxygen bleach powders, which aren't safe on painted surfaces.
Amazon Basics Microfiber Cleaning Cloths
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on walls, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
See what to do for what you're seeing →If the stain was already dried or set, the method changes.
Old, dried or set-in stains →When to call a professional →How to tell it's working
The shadow should lighten with each pass, and the patch should blend into the rest of the wall once it's dry. Water rings or a flat, rubbed look mean you've been too wet or too firm, so ease off and let the area dry before you go back.
What changes for yours
Adjust for your walls
Kitchen walls
Kitchen walls usually carry a thicker, sticky film, so expect to repeat the soap step on the worst areas. Work in small sections and rinse the sponge often so you don't drag grease back across the wall.
Keep the rinse light and dry each section before you move on. Cooking grease near the stove often needs a second pass, so check that area again once the wall is dry.
Cleaning walls before painting
Walls you plan to paint need every trace of grease gone, not just the visible spots. Clean the whole area with the soap solution, then rinse it with a sponge wrung out in clear water.
Let the wall dry fully before you prime. Any spot that still looks dull should be cleaned again before paint goes on.
Hair on walls
Hair grease tends to sit as a faint, oily film around head height, so it can look like a shadow rather than a clear spot. Use the soap solution on that area first, then follow the rest of the steps.
After the rinse, check the wall in side light, since a faint film can hide until it dries. Repeat the soap step on any patch that still looks dull.
Cooking on painted walls
Cooking grease on painted walls is usually a thin film spread over a wide area, not one dark spot. Start with the soap solution on a barely damp sponge and work across the whole patch, not just the darkest part.
Finish with a clean rinse and let the wall dry fully before you judge the result. If a faint film remains, the baking soda paste is the next step for that area only.
Old, dried or set-in stains
Old grease is harder to lift than fresh grease, so expect to repeat the soap solution more than once on an old spot. Work it in small sections and rinse the sponge between passes so the film doesn't spread.
If the spot has dried into the wall, a light wash often comes first, and it may come clean without repainting. If it doesn't, try a solvent-based cleaning solution on a sponge, and for a deeper stain, a mild detergent followed by an abrasive cleaner with water.
If the stain still shows once the wall is dry, seal it with a stain-blocking primer before you paint. Keep the abrasive cleaner to the stubborn patch only and let the wall dry before you judge it.
Vinegar, baking soda, peroxide and more
Do home remedies work on grease on walls?
Plenty of home remedies are meant for fabric, stone or wine, and most of them don't belong on a painted wall. Some remedies help but aren't needed, and others are more than a painted wall can take. The soap solution, baking soda and denatured alcohol are the only ones that go on this wall.

What makes it worse
Mistakes to avoid
Don't stop before the spot is gone
Oil stains tend to reappear just when you think you've seen the last of them. Keep working on the spot and check it again once it's dry, not just while it's wet.
Don't reach for gasoline or lighter fluid
Gasoline, lighter fluid and carbon tetrachloride are not safe cleaners for grease on a wall, and the first two are flammable. Stick to the soap solution and the small-area alcohol step.
Don't rub the grease into the paint
Circular wiping pushes grease deeper into the paint's texture and spreads a bigger shadow. Lift any solids off first, then blot liquids with a dry white cloth.
Don't skip the test on a hidden patch
Every cleaner needs a trial spot, such as behind a door or inside a closet, before it goes on the visible wall. Painted surfaces can change or dull where a product doesn't suit them, and the change may only show once it dries.
Don't use denatured alcohol on big areas
Denatured alcohol is only for the small spots left after the soap has done its job. Put it on a small cloth and keep it away from wide sections of wall.
Troubleshooting
If the stain is still there
Pick what you're seeing:
A shadow remains on painted wall after washing
Repeat mild detergent on a well-wrung sponge once the wall has dried. For a penetrating stain, Sherwin-Williams allows an abrasive cleaner with water after testing a small area.
Wallpaper still looks oily after the blotter
If the paper is washable, use sudsy water and a clear-water wipe, then the Fuller's Earth paste for what remains.
Paneling looks dull after mineral spirits
Apply a wax suitable for wood finish and buff until the sheen evens out.
The cleaned patch looks brighter than the wall
Wash the whole wall section lightly with the same mild suds so the surface looks even.
When to call a professional
A shadow that remains after the steps, or a dull, pale patch where the paint lost its sheen, calls for a paint store visit. If the wall is grasscloth wallpaper rather than paint, a professional cleaner is the safer route.
Questions
Can you cover grease stains on walls?
Yes, but clean the stain first, because it can show through a fresh coat. Once the wall is clean and dry, a stain-blocking primer seals what's left before you paint.
Do I need to start with plain water?
Not usually. Plain water alone won't lift grease, so the soap solution goes first, and plain water is for rinsing.
Why do old grease stains turn yellow?
Grease that isn't fully removed ages and forms yellow stains, and oil stains also darken over time. Clean it early while it's still fresh, because the older it gets, the harder it is to lift.
Will vinegar remove grease from walls?
No, vinegar isn't needed for grease; the soap solution does the work on walls. The soap solution is the step that does the work here.
Is an abrasive scrub sponge safe on painted walls?
Choose a non-abrasive sponge for every step. Scrubbers with abrasive pads can damage the finish, so they don't belong on a painted wall.
How do I know the grease is really gone?
Let the wall dry fully, then look at it in daylight from an angle. A dull or darker patch means grease is still there, so clean that spot again before you paint.
Can I wash a wall that was painted recently?
Not yet, if the paint is under two weeks old. Washing it sooner can change or damage the finish, so until the wait is over, brush off dust with a dry cloth or the soft brush on a vacuum. Once the paint has cured, the usual soap-and-water steps apply.
Will cleaning take the shine off flat paint?
It can, if you press hard or let water sit on it. Matte paint is the most sensitive, so go lightly, keep the sponge only barely damp, and test the cleaner in a hidden spot first. A patch that dries even with no water marks means you got it right.
Is it safe to sponge grease off washable wallpaper?
Only if the paper is washable and you keep the sponge lightly damp. Some textured papers can't take water at all, and grasscloth can call for a pro cleaner. Dry the spot right away and skip any abrasive pad.
