- On skin, remove epoxy resin with a waterless skin cleanser, then wash the area with soap and warm water.
- If epoxy spills on your clothes, change them right away.
- If epoxy or wet foam gets in your eyes, flush them with water for 15 minutes and seek medical attention if discomfort continues.
Epoxy and resin on plastic come off most easily while they're still wet, since a fresh spill hasn't yet hardened into the surface. Plastic can't take abrasive scrubbing, so once the epoxy has cured, every pass has to stay gentle. Expect a fresh spot to lift cleanly and a cured one to take several light passes, if it lifts at all.
Epoxy from plastic comes off best while it's fresh, so don't let a spill sit, and keep the pressure low. Resin from plastic that has cured is a slower job, so give each pass time. If epoxy paint on plastic still won't budge, stop and check the plastic type.

5 steps
Step by step
Step 1 of 5
Wipe up wet epoxy first
Epoxy hardens through a chemical reaction, so anything still wet is the easiest to remove. Lift the bulk of it with paper towels, working from the edge of the spot toward the middle so you don't spread it. If any gets in your eyes, flush them with water for 15 minutes and seek medical attention if discomfort continues.
Tip. Fold the towel to a clean section before every pass.
Careful. Once epoxy has hardened, paper towels and soap will not lift it.
Step 2 of 5
Wash with mild soap and warm water
Wipe the spot with a soft cloth dampened in warm water and a little mild dishwashing liquid. Work in small, even passes over the whole area so the residue lifts off instead of smearing. For containers, hand wash in hot soapy water or use the dishwasher top rack, but only if the product allows it.
Step 3 of 5
Scrub only if the spot resists
If the spot still doesn't budge, use a plastic or nylon pad with light pressure. Work in one direction so you don't leave marks across the surface.
Careful. Abrasive cleansers and scrub pads are off limits on plastic and acrylic.
Step 4 of 5
Rinse and check the spot
Rinse the soap off completely with clean water so no film is left behind. Look at the spot in good light: if it still feels tacky, go back to the soap wash, and if it has hardened, the section on set-in epoxy covers what's left.
Step 5 of 5
Dry with a lint-free cloth
Dry the plastic with a soft, lint-free cloth so no fibers or water spots are left behind. On a phone case, take the phone out first and clean and dry the case with a soft, slightly damp, lint-free cloth.

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:

If the stain was already dried or set, the method changes.

Fresh epoxy stays tacky and smears when you touch it, and that's your window to wipe it up. Once the spot feels hard and doesn't move under a fingertip, it has cured, and the wipe-and-soap steps are no longer the right tool.
What changes for yours
Adjust for your plastic & tupperware
Epoxy paint
Epoxy paint is an epoxy product, so it hardens through the same chemical reaction, and wet paint on plastic is the time to act. Wipe up the wet paint with paper towels, then wash the spot with mild dishwashing liquid and warm water, following the steps above.
Once the paint has cured, no safe removal method is given for plastic, so stop before you try anything harsh. A product that worked on a fresh drip may not be safe on the finished surface, so test a hidden spot before you use anything new.
Phone cases
Take the phone out before you clean anything, so the case can be wiped on its own. A soft, slightly damp, lint-free cloth is the right tool for fresh epoxy on the case.
If the case is silicone, skip window cleaners, household cleaners, aerosol sprays, solvents, ammonia and abrasives. Stick to wiping and drying with the soft cloth, and let the case air-dry fully before you put the phone back in.
Plastic containers and lids
Containers and lids can be washed by hand in hot soapy water, or on the dishwasher top rack if the product allows it. Marker on lids can be rubbed with a soft cloth, and isopropyl alcohol may help with it.
If you microwave food in a container with the lid on, vent or offset the lid so it doesn't warp. Oily, sugary or tomato-based foods can overheat in plastic and leave staining or blistering, so don't push the heat.
Acrylic
On acrylic, the wash steps stay the same, but the rules around what touches the surface are stricter. Solvents and abrasive cleansers are off the list entirely, so don't reach for them even if the spot looks stubborn.
A plastic or nylon pad is the only scrubbing tool that stays in play, and it should be used lightly. Test a small hidden spot before any new product touches the surface.
Old, dried or set-in stains
Epoxy that has been on plastic for a while is much harder than a fresh drip, and there's no safe method for lifting cured epoxy from plastic here. Vinegar, baking soda and peroxide won't fix it either, so leave them in the cupboard.
If the epoxy has dried on the surface, scraping or grinding it off will damage the finish on plastic. The one exception is cured spray foam, which has to be scraped off the surface, so test a hidden spot first and scrape slowly.
If a mark is still there after you've been gentle, accept that it may not come off, and stop before you damage the plastic. On a lid or case you use every day, replacing it may be the sensible call.

What makes it worse
Mistakes to avoid
Don't wait for the epoxy to cure
Epoxy that's still wet comes off far more easily than cured epoxy, so act the moment a drip lands. Once it hardens, stop scrubbing, test only the mild dish-soap wash on a hidden spot, and ask a plastics repair shop before you try anything stronger.
Don't use solvents on your skin
Solvents don't belong in skin cleanup for epoxy, even when they seem like the obvious choice. Stick to the waterless cleanser and the soap and warm water from the first aid notes, and skip other products some people reach for.
Don't work near pilot lights
Spray foam is a flammable aerosol, so shut off pilot lights and other ignition sources while you use it. Keep the area clear of any flame until you're done.
Don't use heat to loosen the epoxy
Plastic lids and containers should never go on or under a flame, stovetop or broiler. No heat method is given for loosening epoxy on plastic, so don't try a flame or a hot oven.
When to call a professional
If the mark matters on an item you can't replace, a repair shop that works with plastics can tell you what they can safely try. Ask about the material and the finish before anyone tries a stronger cleaner on it.
Questions
Can you remove epoxy from plastic once it has dried?
There's no safe method here for lifting cured epoxy from plastic, so stop before you scrub. Keep the cleanup gentle and accept that a mark may stay.
Does vinegar remove resin from plastic?
No, wet resin is best handled with paper towels and mild dishwashing liquid in warm water. Wet resin is best handled with paper towels and mild dishwashing liquid in warm water.
Can I use rubbing alcohol on epoxy paint?
Isopropyl alcohol is named only for stubborn marker on plastic lids, not for epoxy paint. For wet paint, paper towels and mild soap are the right approach.
Can I wash a plastic container in hot water?
Containers can be washed by hand in hot soapy water or on the dishwasher top rack, but only if the product allows it. If the product doesn't say, stick to warm water.
Will epoxy come off a phone case?
Fresh epoxy can be wiped off after you take the phone out. The cloth you use should be soft, slightly damp and lint-free.
How do I know if the epoxy has cured?
Press a corner of a dry paper towel onto the spot. If anything transfers or the spot still feels tacky, it's soft and worth wiping now.
