- Judge the damage first: light browning may come out, but charred or deep burns usually won't.
- Test any cleaner or bleach on a hidden spot before using it.
- Work gently, because harsh tools strip the finish.
- Wear rubber gloves and ventilate when using strong chemicals.
A scorch on plastic is heat damage to the plastic itself, so it doesn't lift the way a food stain does. Light browning sometimes fades with gentle washing, while charred or deep burns usually stay. Heat is off the table on either kind, so keep the plastic away from it while you work.
Getting a heat mark off a PVC fitting without heat is slow work, so give a mild cleaner time to loosen it. Test any product on a hidden spot first, since some plastics cloud under harsh cleaners. If the stove trim still looks marked after a few rounds, a gentle plastic cleaner is the next thing to try.

5 steps
Step by step
Step 1 of 5
Judge how deep the damage goes
Look at the mark in good light. Light browning may come out with cleaning, but charred, melted or deep burns usually can't be reversed and may need a professional repair.
If the plastic is warped or has a hole, cleaning won't fix it, so stop here.
Step 2 of 5
Test your cleaner on a hidden spot
Pick a spot that won't show, like the underside of a lid or the back of a seat. Dampen the cloth with the mild soap and warm water, then check the plastic for dulling or color change before you move on.
Careful. Pretest every cleaning agent on an inconspicuous area first.
Step 3 of 5
Wash the mark gently
Dampen a soft, slightly damp lint-free cloth in mild soap and warm water. Wipe the scorched area in small, light strokes, and let the soapy water do the work rather than pressing hard.
Tip. Work in short passes and stop when the mark stops lifting.
Step 4 of 5
Rinse and dry the surface
Wipe the area with clean water to remove every trace of soap, since leftover residue can dull the plastic. Dry it with a clean soft cloth, then look at the mark in daylight to see how much it has faded.
Step 5 of 5
Keep the plastic away from heat
Heat is what caused this damage, so keep the plastic away from it from now on. Let it cool completely before you handle or store it.
Careful. Don't put plastic lids or containers on or under a flame, stovetop or broiler.

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
Light browning that fades after washing and drying is a good sign the damage is shallow. If the mark looks the same or the plastic feels rough, dull or soft, stop and treat it as deep damage.
What changes for yours
Adjust for your plastic & tupperware
Plastic lids and food containers
Lids and containers get the same mild soap and warm water wash, and washable containers can be hand washed in hot soapy water with the plastic handled gently. Keep lids vented or offset in the microwave so they don't warp.
Tomato and acidic sauces can stain lids, so rinse them soon after use. Heat damage from a stovetop or broiler still can't be reversed by washing, so the same limit applies.
Plastic toilet seats
Plastic toilet seats take mild soap and warm water, and a soft, slightly damp lint-free cloth is all you need. Keep nail polish, aftershave and abrasive chemicals away from the seat, since they damage the finish.
If the mark is on the hinge or under the seat, follow the same wash and stop when the finish starts to dull.
Plastic kitchen countertops
This method applies only to Corian and acrylic plastic, not vinyl, so check what your counter is before you start. Use the mild soap and warm water wash from the steps on it.
Corian and acrylic take the same light-browning limit as other plastic, so a deep scorch will stay. Keep solvents off acrylic, since they can dull or damage it.
Plastic stove trim
Plastic knobs, trim and panels near burners can scorch, and no flame or direct heat is safe for them. Clean the discolored trim with mild soap and warm water, then rinse and dry it.
If the mark is on the metal panel rather than the plastic, the Stainless Steel & Appliances guide covers that surface.
Old, dried or set-in stains
If the mark has been there for a long time, or the plastic has been heated again since, the scorch is probably too deep to lift. Light browning that has set can sometimes be bleached out, but deep marks usually leave permanent discoloration.
Chlorine or perborate laundry bleach is the only stronger option, and it goes on a cotton ball or folded absorbent cloth touching just the mark. Test it on a hidden spot first, then rinse with soapy water and dry before you judge the result.
If the mark is still there after that, accept that it's permanent and stop, because bleaching can damage the finish. A professional repair is the realistic next step for charred or deep burns.
Vinegar, baking soda, peroxide and more
Do home remedies work on scorch on plastic & tupperware?
Most kitchen remedies don't do anything for a scorch, because the damage is in the plastic itself rather than on it. Mild soap and warm water are all it takes. Stronger remedies can't undo heat damage inside the plastic, so skip them.

What makes it worse
Mistakes to avoid
Don't scrub the mark with abrasives
Abrasive cleansers, steel wool and sandpaper can dull or scratch plastic and make the finish worse. If scouring is really needed, use only a plastic or nylon pad, and reach for the soft cloth first.
Don't microwave plastic with the lid sealed
Vent or offset the lid so it can't seal shut, which keeps the plastic from warping. A sealed lid traps heat and can distort the container.
Don't overheat fatty or tomato foods in plastic
High-fat foods, sugar, oils and tomato sauce can cause staining and blistering when plastic gets too hot. Keep the heat moderate so the food doesn't cook onto the surface.
Don't leave plastic in extreme heat
A hot car is extreme heat that can damage plastic, including glasses and containers. Keep plastic items out of the sun and off hot surfaces.
When to call a professional
Charred, melted or deep burns usually can't be cleaned out, and a professional repair is the realistic option. If the damaged part is attached to something you can't take apart, ask a repair specialist rather than heating it to loosen it.
Questions
How do I remove a PVC fitting without heat?
Don't try to force the fitting apart without heat. Heat is what damages plastic, so don't add a torch or flame to loosen it. For a stuck fitting, a plumber or repair specialist can advise on the safest removal.
Can I clean heat stains on the plastic part of my stove?
Yes, for light browning: wash the trim with mild soap and warm water, then rinse and dry it. Keep it away from flame and direct heat from then on, and expect deep marks to stay.
Will a scorch on plastic ever come out completely?
Light browning sometimes fades, but charred or deep scorch usually leaves permanent discoloration. Try the gentle cleaning first, and if it doesn't improve, the damage is probably set.
Is bleach safe on plastic?
Chlorine or perborate laundry bleach is the stronger option, used only after testing on a hidden spot. Put it on a cotton ball, touch only the mark, then rinse and dry thoroughly.
Can I use vinegar or baking soda on a plastic scorch?
No: vinegar doesn't lift burn damage, and baking soda is an abrasive that plastic can't take. Stick to mild soap and warm water for the first attempt.
How do I know whether a scorch is light or deep?
Light browning is a surface tint that looks lighter after you wipe it. Charred, blackened or melted plastic is deep damage, and cleaning won't reverse it.
Can I put a scorched plastic lid in the microwave?
Only with the lid vented or offset, never sealed. Sealed lids can warp, and heat is what damages the plastic in the first place.
