First few minutes
Just happened? Do this first
- Unplug the device and remove the cables before you touch the stain.
- Pick off large pieces by hand, and don't rub wet dough across the surface.
- Chill putty with ice cubes in a sealed bag, then scrape it with a plastic card.
- Don't spray or pour anything onto the device.
Putty on electronics is tough to clean because a device can't be soaked, scrubbed or sprayed, so every bit of moisture needs a reason. Dried putty stays soft enough to be pulled away from a surface, which makes slow, careful lifting the best starting point. Leather or fabric cases, screens and cables each react differently, so check what the device is made of before you choose how much moisture to use.
Dab with a barely damp microfiber cloth and wipe away from ports and vents so moisture stays out. Putty on a phone screen or keyboard only needs a light touch, so stop as soon as it lifts. If a film sticks around after a few gentle passes, stop and have a pro look at it rather than pushing harder.

6 steps
Step by step
Step 1 of 6
Unplug the device first
Disconnect the device and remove all cables and external power before you touch the stain. Set it on a dry, stable surface where you can see the mark clearly.
Step 2 of 6
Pick off and chill the residue
Lift off any large wet or dry pieces of dough by hand, and don't rub wet dough across the surface. For putty, hold a few ice cubes sealed in a bag against it until it hardens, then scrape the hardened bits with a plastic card or a dull-edged knife.
Step 3 of 6
Test alcohol on a hidden spot
Pick a hidden spot, such as the back edge or inside a seam. Dab a little 70% isopropyl alcohol on a cloth, touch it to that spot, and wait a minute before you look for any change.
Careful. Alcohol can change some finishes, so stop if the test spot shows any change.
Step 4 of 6
Wipe with a dry cloth
Wipe the surface with a soft, dry, lint-free cloth to lift loose residue and dust. Work in one direction, and fold the cloth to a clean side as it fills.
Tip. Switch to a clean side with each pass so residue doesn't smear back across the surface.
Step 5 of 6
Dampen the cloth for remaining marks
If a mark remains, switch to a soft, slightly damp, lint-free cloth and wipe gently. On screens, apply the screen cleaner to the cloth, never to the screen, then wipe the mark away.
Careful. Keep moisture out of every opening, and never submerge the device.
Step 6 of 6
Use alcohol on hard smudges
For smudges that stay, gently wipe hard, nonporous surfaces with a cloth moistened with 70% isopropyl alcohol or a 75% ethyl alcohol wipe. Use light pressure and move to a clean area of the cloth as it picks up residue.
Careful. Put the alcohol on the cloth, never directly on the device.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on electronics & screens, 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.
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 mark is gone when the cloth comes away clean and the area looks even with the rest of the device. A faint haze that shows only in angled light usually means one more pass with the damp cloth, not a stronger liquid. Stop if the surface looks dull or tacky, and let the device dry fully before you reconnect it.
What changes for yours
Adjust for your electronics & screens
Screens and displays
Screens take the least moisture of anything on the device, so skip the damp cloth unless the dry wipe fails. Use screen cleaner applied to the cloth, never sprayed on the screen, and keep the alcohol for smudges that remain. Never use acetone, window cleaners or household cleaners on a display.
If putty has pressed into the edge of the screen, lift it with a plastic card held flat against the glass. Chill it first so the edge lifts cleanly.
Keyboards and vents
Dough and putty can work into gaps between keys and into vents, where moisture is the real risk. Pick out pieces with a plastic card or a dry cloth wrapped around a flat edge, and don't press them deeper.
Use the slightly damp cloth only on key tops, and never let it reach a vent or port. Turn the device so loose debris falls out before you scrape anything, and let it dry fully before plugging it back in.
Hard plastic or metal cases
A hard, nonporous case is where the alcohol wipe belongs, once the test spot shows no change. Chill any putty first so it lifts cleanly, then scrape with a plastic card and wipe the seams gently. Keep the alcohol light, so it doesn't pool in the seams.
If a smudge remains after the alcohol wipe, repeat the damp-cloth step rather than adding a stronger product.
Leather or fabric cases
These steps don't cover leather or fabric cases, so don't assume the same methods are safe. Pick off the pieces by hand and wipe with a dry, soft, lint-free cloth only.
If a mark remains, leave it alone and ask the device's maker or a professional what's safe for that exact case. Keep all liquid and solvent away from it until you know the material.
Cables and chargers
Unplug the cable and keep it disconnected from any port while you clean it. Chill any putty on the jacket with ice in a sealed bag, then lift the pieces off with a dry cloth. Keep the damp cloth away from connectors.
A cable that has been wet needs to dry completely before you use it.
Old, dried or set-in stains
A stain that has sat on a device for days is harder to lift, and a faint mark may remain. Start again by unplugging the device and chilling any putty, then work through the scrape and wipes slowly.
Dried putty stays fairly pliable, so it often pulls off a hard surface once it's chilled. Use the 70% isopropyl alcohol wipe on what's left, pressing lightly and switching to a clean section of cloth on each pass. Stop as soon as the cloth shows no more residue.
Some residue can stay even after careful work, especially in seams and openings. Don't increase the strength of the liquid or reach for a stronger solvent to chase it. If the mark still shows, a technician is a better choice than more cleaning at home.
Vinegar, baking soda, peroxide and more
Do home remedies work on slime and putty on electronics & screens?
Most kitchen remedies don't belong on electronics, because they're wet, grainy or bleach-based. On screens, 70% isopropyl alcohol is the one remedy that belongs.

What makes it worse
Mistakes to avoid
Don't use bleach or hydrogen peroxide
Neither is safe on this surface, and that includes oxygen-bleach products used for stains. Check the label on any wipe before you grab it from under the sink.
Don't use paper towels or abrasives
Paper towels can leave fibers, and abrasive cloths or cleaners can scratch or mark the surface. Use only soft, dry, lint-free cloths, and dampen them only when the dry wipe fails.
Don't use acetone or amyl acetate on displays
Acetone and cleaners containing it are not safe on displays, and amyl acetate belongs off plastics too. Skip nail-polish remover as well, even for a small spot.
Don't leave the device connected
Unplugging first keeps power away from the parts you're cleaning. Wait until the device is completely dry before you reconnect any cable.
When to call a professional
If liquid gets inside the device, keep it unplugged and get help from an authorized service provider for that brand before you use it again. Don't try to dry out openings with heat, because that can push the liquid further in.
Questions
Is putty harder to remove once it dries?
Not always. Putty stays fairly pliable when it dries, so it can often be pulled off a hard surface. Chill it with ice cubes in a sealed bag first so it lifts cleanly.
Can I use heat to soften dough on a device?
No. No, heat is a risk for an electronic device. Chill the putty instead, and lift dough off by hand while it's still soft. Chill putty instead, and lift dough off by hand while it's still soft.
Should I use screen cleaner or alcohol?
Start with a screen cleaner made for screens, applied to a soft cloth. Keep the 70% isopropyl alcohol for smudges that remain on hard, nonporous surfaces, and test it on a hidden spot first.
Can I clean a leather case the same way?
These steps don't cover leather, so don't use them on it. Keep the case dry, lift off pieces by hand, and wipe with a dry, soft cloth until you know what the material is.
How long should a device dry after cleaning?
Let it air dry fully before you plug anything in or power it on. Don't speed the drying with heat, and keep the cables disconnected until the device is dry.
Can I use baking soda as a gentle scrub?
No. Baking soda is an abrasive, and abrasives aren't allowed on this device. Use a soft, lint-free cloth and the alcohol wipe for smudges that remain.
