- Scrape off surface wax with a dull knife.
- Don't warm the wax with a flame, iron or heater.
- Keep the cleaning gentle and skip scouring pads.
Candle wax on plastic comes off best while it's still solid, so start by hardening it with ice in a plastic bag. Once it's brittle, a dull knife can take the bulk away, and mild detergent and water handle the film that remains. Plastic can't take heat or rough scrubbing, so keep the wipe light and the tools soft.
If the wax is on plastic trim or molding, keep the knife flat and shallow so you don't gouge the surface. Old wax on plastic molding often leaves a film, so give the soapy water more time before you press harder. If the trim starts to look dull, stop and rinse it off.

5 steps
Step by step
Step 1 of 5
Harden the wax with ice
Put an ice cube in a plastic bag and hold it against the wax until the wax firms up. Solid wax breaks off in flakes, which is much easier than wiping soft wax across the plastic. Keep the bag on the spot until the edges look brittle.
Careful. Don't warm the wax with a flame, iron or heater, because heat melts it into the surface and can mark the plastic.
Step 2 of 5
Scrape away the hardened wax
Scrape the wax off with a dull knife, spoon, spatula or the edge of a plastic credit card. Work from the outside of the spot toward the middle so the wax doesn't spread. Stop when only a thin film or a colored mark is left.
Tip. A colored candle can leave a faint dye mark once the wax is gone, and the next step is where that gets wiped.
Careful. Keep the blade dull and the pressure light, because plastic scratches easily.
Step 3 of 5
Wipe with the cleaning mix
Dip a sponge or soft cloth in a soda-based cleaner dissolved in water, or in a detergent and water mix, and wipe the spot. Keep the cloth damp rather than dripping, and work over the film until it lifts off. Switch to a clean section of cloth as it picks up wax.
Careful. If you use a soda-based cleaner, follow the directions and cautions on the container.
Step 4 of 5
Rinse with clear water
Rinse well with a sponge or cloth dipped in clear water, wiping away every trace of the cleaning mix. Repeat with clean water until the surface doesn't feel slick.
Step 5 of 5
Dry the surface
Wipe the surface dry with a soft clean cloth until no moisture shows. Use a cloth with a smooth weave, since a rough one can leave fine scratches.

Best products for candle wax on plastic & tupperware
Use a plain soda-based cleaner or a mild liquid detergent for the cleaning mix. Skip soap-based products and anything made for fabric or carpet.

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 spot is done when the surface feels smooth and no waxy film shows when you run a clean fingertip across it. A faint colored mark can remain after the wax is gone, and that doesn't mean the wax is still there. If the surface still feels greasy or tacky, repeat the scrape and the wipe before rinsing.
What changes for yours
Adjust for your plastic & tupperware
Plastic trim
Trim has ridges and corners where wax collects, so scrape along the length of the trim rather than across it. Wrap the soft cloth around a cotton swab or use the tip of the plastic credit card to reach the grooves, and keep the pressure light.
The ice, wipe and rinse steps stay the same, but keep the cleaning mix on the trim itself rather than letting it run onto nearby surfaces. Dry each section before you move on, so the corners don't hold moisture.
Colored candle wax
Colored candles can leave a dye mark that stays after the wax is gone, so the wipe step is where the color lifts. Work the cleaning mix in small passes and check the mark between passes.
If the dye is still visible after the wipe and rinse, repeat those two steps once and then stop, because more rubbing wears the surface.
Plastic lids and containers
Lids and containers can't take any direct heat, so the ice and scrape steps happen away from any flame or stovetop. Keep the cleaning mix to the wax area, and don't soak the lid, because seals and hinges hold moisture. Work on one area at a time so the rest of the item stays dry.
Once the wax is gone, rinse thoroughly and let the lid dry completely before reassembling it, so no moisture stays trapped under the seal.
Acrylic pieces
Acrylic can't take solvents or abrasive cleansers, so the wipe step uses only the cleaning mix and a soft cloth, even for a stubborn mark. Keep the scrape light and wipe in one direction so the surface stays clear.
Dry the piece with a soft clean cloth and check it under good light before deciding it's done.
Old, dried or set-in stains
Old wax is handled the same way, because it firms up in the ice and lifts in the same flakes. Repeat the ice and scrape on any remaining wax, then do the wipe and rinse a second time. Keep the cleaning mix moving over the spot rather than letting it sit.
Wax that has been on molding for a long time often leaves a clear film or colored mark behind after the wax itself is gone. Repeating the steps usually clears the wax, but the dye may take more passes. Pushing harder only wears the surface.
If a faint mark is still there after two full rounds, leave it alone rather than trying a stronger product on plastic. A light mark is the realistic result on this material, and it doesn't mean the surface is damaged.
Vinegar, baking soda, peroxide and more
Do home remedies work on candle wax on plastic & tupperware?
Most household remedies don't help with candle wax on plastic, and several can damage the surface. Only the ice-and-scrape approach with a mild detergent suits plastic; the rest can damage the surface. The steps above are the only method recommended here.

What makes it worse
Mistakes to avoid
Don't scrub with abrasives
Scouring pads and abrasive cleansers leave fine scratches that make the plastic look dull and hazy. If a film remains after the wipe, repeat the cleaning step with the damp cloth instead.
Don't use plain soap
Skip plain soap on plastic; use the soda-based cleaner or detergent mix and rinse with clear water. Stick to the soda-based cleaner or detergent mix and rinse it out with clear water.
Don't mix cleaners
Never mix chlorine bleach with ammonia, vinegar or rubbing alcohol, and don't use bleach on this stain at all. Rinse the spot with plain water between any two products, because mixed products can give off hazardous fumes.
When to call a professional
If the plastic is cracked, clouded or the mark won't lift after several gentle rounds, stop and have the item's maker or a repair shop look at it. Trying harsher products at that point usually makes the damage worse.
Questions
Can I use an iron to melt the wax off plastic?
No. An iron puts direct heat on plastic, which can warp it and push the wax deeper into the surface. Harden the wax with ice and scrape it off instead.
Will hot water help the wax come off?
Hot water softens the wax and spreads it, so it's better to keep the wax firm with ice. Warm water is fine for the cleaning mix and the rinse.
Can I use vinegar or baking soda on plastic?
No. Both are poor choices for this wax on plastic. Baking soda acts as an abrasive on plastic, and vinegar doesn't lift wax, so stick to the soda-based cleaner or detergent mix.
Will the colored dye from a candle come out?
Most of it often lifts with repeated gentle wipes, but a faint mark can stay once the wax is gone. Accept a light color rather than rubbing the spot until the plastic looks worn.
Can I use nail polish remover or rubbing alcohol?
No. Rubbing alcohol doesn't dissolve candle wax, and acrylic can't take solvents, so nail polish remover is a poor pick too.
Those products can leave their own film or dull the surface. Stick to the cleaning mix and the ice-and-scrape steps.
What if the wax has been on the plastic for weeks?
Old wax takes the same ice-and-scrape approach, but it often needs a second round. Repeat the steps before deciding the mark is permanent, and accept a faint color if it's still there.
Can I use a metal knife to scrape the wax?
Only if it's dull and you keep the pressure light. A sharp edge can cut into plastic, so a spoon or the edge of a plastic credit card is the safer choice.
