First few minutes
Just happened? Do this first
- Pick off the large pieces by hand first, and don't rub them into the paint.
- If the putty is thick, chill it with ice cubes so it hardens, then scrape off what you can with a dull knife or spoon.
- Scrape hard surfaces gently with a dull-edged knife, spatula or plastic card.
- Test any solvent, such as rubbing alcohol, on a hidden spot first.
Sticky putty on a painted wall leaves an oily smudge that spreads into the paint if you press on it, so the first goal is lifting, not rubbing. Fresh marks come off with warm water and a little dish soap, but a mark that has been sitting for weeks may only fade with repeated light treatment. Flat or matte paint is the main worry here, and wallpaper needs a different approach altogether.
If you're trying to get blu tack stains off walls, test a small hidden spot before you go further. Old blu tack from walls usually needs a few light passes, and a firm scrub can take the paint with it. Save a scouring cleanser for stubborn marks, and only after gentler tries have failed.

5 steps
Step by step
Step 1 of 5
Lift off the bulk by hand
Pick off the large pieces of putty by hand, pulling gently rather than tugging at them. Working this way keeps the putty from being pressed further into the paint while you clean.
Step 2 of 5
Dampen and soap the towel
Dampen paper towels with warm water and apply liquid dish soap. Wring the towel out well so it's damp rather than dripping before it touches the wall.
Step 3 of 5
Loosen the putty in circles
Use the soapy towel in a circular motion to loosen and remove as much putty as you can. Keep folding to a clean section as the towel picks up residue, so you aren't spreading it around.
Tip. Work in small circles rather than long strokes, so the putty gathers instead of smearing.
Careful. Use non-abrasive sponges or cloths; abrasive pads can scratch painted walls.
Step 4 of 5
Clear the greasy residue
Spray the residue with all-purpose cleaner and wipe it with paper towels. Spray only onto the residue itself, not across the wider wall, and wipe each pass before moving on.
Step 5 of 5
Repeat, then wipe clean
Repeat the soap and cleaner steps as needed until no putty or greasy ring is left. Finish by wiping the area with a damp cloth of plain water, and let it dry before you judge the result.

Best products for slime and putty on walls
A plain liquid dish soap and an all-purpose cleaner are all you need for the residue. Stick with those two and repeat them until the ring is gone.
Goo Gone Pro-Power Goo & Adhesive Remover
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
Look for the oily ring to lighten on each pass, and for the paint to dry evenly with no shiny halo. A patch that stays smudged after two careful rounds has set into the paint, so switch to the old-mark section.
What changes for yours
Adjust for your walls
Poster putty
Poster putty responds to chilling, so start there when the residue is thick. Hold ice cubes against it until it firms up, then scrape off as much as you can with a dull knife or spoon.
Once the bulk is gone, go back to the warm-water dish-soap towel and the all-purpose cleaner for the film left on the paint. Scrape gently, since hard pressure can damage matte paint.
Sticky tack
Sticky tack is handled the same way as putty on a wall, so the warm-water dish-soap towel and all-purpose cleaner steps apply. Lift the big pieces by hand first so you don't smear them further into the paint.
If a greasy ring is left after that, the rubbing alcohol treatment in the set-in part is the next step, and it needs a hidden-spot test first.
Old, dried or set-in stains
Old sticky putty has usually been pressed into the paint for a while, so its oil may have spread into the surface. Start with the same warm-water dish-soap towel and all-purpose cleaner steps, and give the towel a few passes before you judge the result.
Dried putty often stays pliable enough to pull off in pieces, so try a gentle scrape with a dull knife or plastic card on hard surfaces, keeping the pressure light on painted walls. Stronger treatments are for what's left after that, not the first attempt.
If an oily ring still shows, dab a small amount of rubbing alcohol onto a cotton ball, after testing a hidden spot first. Use only a little, blot with a clean cloth, and stop if the paint starts to change. If a faint mark still shows after that, it can be sealed with a stain-blocking primer before you repaint.

Do home remedies work on slime and putty on walls?
Plenty of home remedies are built for fabric, stone or other surfaces, and most of them don't belong on a painted wall. Only a couple are worth using here, and the ones that matter are already covered in the steps and the set-in part.

What makes it worse
Mistakes to avoid
Don't pull hard on a stuck piece
Yanking sticky putty can smear it across the paint or lift the paint with it. Work it loose with the soapy towel in small circles instead, and stop if the paint starts to peel.
Don't rub the putty into the wall
Rubbing spreads the oil over a wider patch, which makes the ring harder to clear. Pick off the big pieces first, then loosen what's left with a damp towel.
Don't scrape with a fingernail or blade
A blade or nail can gouge painted walls and leave a bright scratch that's harder to hide than the oily mark. If the putty is firm, use a dull plastic card held flat instead.
Don't reach for bleach on a putty mark
Bleach is only for mildew on painted walls, so it has no role in lifting putty. Using it on an oily smudge can change the color of the paint in that patch.
Don't wipe over the same spot with a soggy towel
Repeated wet passes over one patch leave water marks and can soften the paint around the edge. Fold the towel to a clean section after each pass, and work outward from the mark.
Troubleshooting
If the stain is still there
Pick what you're seeing:
A greasy shadow remains after the putty is gone.
Go back to the soapy towel and the All Purpose cleaner for another round. If it still shows once dry, see the set-in section for washing and sealing before repainting.
Putty smears instead of lifting.
It is too warm and soft. Chill it with ice cubes in a bag until firm, then scrape again with a plastic card.
Small specks are stuck in textured paint.
Press a clean lump of the same putty onto the specks and lift. Then wipe with the soapy towel in small circles.
The paint looks shinier where you cleaned.
Stop cleaning that spot. Touch up with paint of the same color and sheen if the change stays after drying.
When to call a professional
A pale or dull patch that stays after your gentle rounds is a touch-up question for a paint store, not a reason to keep scrubbing. Tell them it's sticky putty, and whether the paint is flat or satin. If the surface is wallpaper, especially grasscloth, have a professional look before anything wet touches it.
Questions
Does blu tack stain walls?
Yes, it can leave an oily mark on painted walls. Lift off the bulk, then clean the residue with the soapy towel and all-purpose cleaner so the mark has less to hold onto.
What makes sticky putty leave a mark?
Sticky putty is a putty, and putties carry fats, oils and waxes that can leave a greasy mark on paint. Clearing it early keeps that oil from spreading, which makes the mark easier to remove.
Can I remove sticky putty from painted walls without removing the paint?
Yes, if you keep the cleaning light. Use warm water, dish soap and a non-abrasive cloth, and avoid soaking the wall or pressing hard.
Can rubbing alcohol damage the paint?
It can, because strong solvents can damage the finish, so test it on a hidden spot before using it. Use only a small amount on the oily ring and blot it off rather than letting it sit.
What do I do with putty that has been on the wall for weeks?
Dried putty often stays pliable enough to pull off in pieces, so start there before you use any solvent. Work the rest with the soapy towel and all-purpose cleaner, and use the set-in options only if a greasy ring remains.
Can I paint over a mark left by sticky putty?
Yes, once the wall is clean and fully dry. If a faint mark still shows, seal it with a stain-blocking primer before you repaint.
Can I clean sticky putty off a wall I painted recently?
Not with water yet. Fresh paint needs time to cure before it can handle any moisture, so wait about two weeks and dust the spot with a dry cloth until then. After that, use the gentle warm-water steps, testing a small patch first.
Can I use a sponge on washable wallpaper with putty on it?
Yes, but keep the sponge barely damp and skip any abrasive cleaner. Work the putty off in small circles with a soft plastic card or your fingertip, then dry the paper right away. Textured papers may not be washable at all, so test a hidden strip before you commit.
Which direction should I wipe when a putty mark is on the wall?
Work from the outside of the mark toward the middle, so you don't drag the oily ring across clean paint. Rinse or refold the towel often, so it isn't carrying residue back onto the wall. Keep the strokes short and light, and let the spot dry before you judge it.
