- Scrape off extra crayon with a dull edge, such as a plastic card.
- Pretest any cleaner on a hidden spot first.
- Use only small amounts of solvent and blot instead of soaking.
Crayon on plastic is really wax carrying color, so the wax has to be dissolved or cut before the color lifts. Plastic scratches easily and can't take heat, so every step needs to stay small and gentle. A crayon mark that has been warmed and set is a slower job than a fresh one, and it's worth checking your method on a hidden spot first.
Work in a cool spot so the surface doesn't warm up as you go. Crayon on a plastic table usually responds to short, slow passes, while plastic in a car may need a few more rounds. Quit the moment the surface starts to look hazy, because a scratch is harder to fix than a leftover mark.

5 steps
Step by step
Step 1 of 5
Scrape off the loose crayon
Hold a plastic credit card or dull knife at a low angle and lift the crayon off in short, light strokes. Stop when the thick wax is gone, since the wipes will take the rest. Don't press hard, and don't switch to a sharp tool.
Careful. Don't scratch hard surfaces while scraping; use the dull edge of a plastic card.
Step 2 of 5
Wipe with a mild detergent solution
Dip a sponge in warm water with mild detergent dissolved in it, and wipe the marked area. The wax part of crayon is greasy, so the detergent loosens the film that scraping leaves behind. Keep wiping until color starts to lift onto the sponge.
Step 3 of 5
Rinse and dry the surface
Rinse the sponge in clean water and wipe the area again to take off the detergent. Dry it well with a clean cloth before you go on.
Step 4 of 5
Sponge the wax with solvent
Dampen a clean sponge lightly with dry-cleaning fluid or naphtha and dab the marks, working one small area at a time. Keep the sponge barely damp and turn to a clean section often so you don't spread the wax around.
Careful. Keep the room ventilated and keep flame and sparks away from the solvent.
Step 5 of 5
Blot dry and check the surface
Blot the area dry with a clean cloth. If faint color or wax is still visible, repeat the solvent sponge on that spot only, then blot again.

Best products for crayon on plastic & tupperware
Look for a mild dish detergent and a small bottle of dry-cleaning fluid or naphtha, which most hardware stores carry. Keep both away from heat and open flames.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on plastic & tupperware, 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 wax should come up onto the sponge during the first wipes, and the color should lift with it. A faint film after the surface dries usually means one more light solvent pass, not a harder scrub.
What changes for yours
Adjust for your plastic & tupperware
Plastic table
A table top is large and flat, so work in small sections and keep solvent away from seams and edges where it can soak in. The steps stay the same, but use the detergent wipe across the whole surface before you touch any spot with solvent.
If the table has a glossy finish, a light touch is enough, and a dull patch after drying means you pressed too hard. If you can't tell whether the finish is sealed, do the test on a hidden spot first.
Plastic in a car
Hard plastic trim, the dashboard and door panels take the same steps, with the car parked in shade and the windows open so the air keeps moving. Keep the sponge barely damp and work only on the hard plastic, away from the glass.
If the crayon is on the seats, fabric or leather, follow the Car Seats guide instead, since those surfaces need different care.
Old, dried or set-in stains
Old crayon that has sat on plastic for a long time can be hard to lift, because the wax may have worked into the grain of the surface. There isn't a proven set-in method for crayon on plastic, so the steps above are the base.
If marks have dried on, repeat the solvent sponge on that spot and blot dry. Stronger products are not a safe next step on plastic, so the solvent pass is the limit.
Keep the work gentle through each pass, and don't let a scrub pad push the wax deeper. If it's still there after repeated passes, accept that some residue may stay rather than damage the finish.

Do home remedies work on crayon on plastic & tupperware?
Most kitchen remedies don't touch crayon wax, so a mild detergent and a little dry-cleaning fluid do the real work. Each remedy below says whether it's in the steps, whether it helps on the side, or whether plastic can't take it.

What makes it worse
Mistakes to avoid
Don't use abrasive cleansers or scrub pads
Plastic scratches easily, and a scratched patch looks dull and collects marks more readily. Stick to the detergent wipe and the solvent sponge, and repeat them gently if needed.
Don't use gasoline, lighter fluid or carbon tetrachloride
These are harsh solvents that can damage plastic and are dangerous to use indoors. Dry-cleaning fluid or naphtha, used in small amounts, is the solvent that lifts the wax.
Don't mix cleaning products on the same spot
Mixed products can give off hazardous fumes, especially chlorine bleach with ammonia. If you need more than one product, rinse the area thoroughly between them.
When to call a professional
If the crayon won't lift after these steps and the piece is valuable or built into something, stop before trying harder methods. Ask the manufacturer for its cleaning advice or hire a cleaning professional who handles plastics.
Questions
Does water alone remove crayon from plastic?
Usually not. Water wets the surface but doesn't loosen the wax, so the crayon smears and stays. Start with the detergent wipe, then use the solvent sponge on the wax that remains.
Can I use vinegar on crayon marks?
No. No, vinegar doesn't loosen crayon wax; the detergent wipe and solvent sponge do the work. The detergent wipe and the solvent sponge do the work instead.
Will the marks come off a plastic table?
Yes, usually, if the table is hard plastic and you work in small sections. Start with the detergent wipe, then use the solvent on any wax left after it dries.
Is acrylic the same as plastic?
Acrylic is a plastic, but it needs stricter care here. Don't use solvents or abrasives on acrylic, so use only warm water and mild detergent and dry it well.
Can I use a stronger product if a mark is still there?
It's not a safe next step on plastic. Repeat the solvent sponge on that spot and blot dry, and if a faint mark remains, accept it rather than risk the finish.
Can I speed it up with heat?
No. Plastic can't take flame or direct heat, and heat can warp it while the wax spreads deeper. Keep the work at room temperature and follow the steps.
