- Gently scrape off excess paste with a dull knife or spatula, without forcing it deeper.
- Rinse with cool or cold water to dilute the stain.
- Blot rather than rub.
- Do not dry or iron until the mark is gone.
Toothpaste on plastic leaves a white or colored mark, because the paste and its dyes need lifting rather than rubbing into the surface. Most plastic items handle a gentle wash well, so a fresh mark often comes off in one pass. Paste left on for days can need a second full treatment, with air drying between attempts.
Toothpaste stains on plastic containers and lids usually lift with a mild wash, but acrylic needs a softer touch. Eyeglass lenses and phone cases are the delicate ones, so use a soft cloth and light pressure. Skip anything abrasive, because scrubbing a clear surface is how it ends up cloudy.

6 steps
Step by step
Step 1 of 6
Scrape off the excess paste
Use a dull knife or spatula to lift away whatever paste is sitting on top of the plastic. Work from the edge toward the middle so the paste doesn't spread across the surface.
Step 2 of 6
Rinse and blot with cool water
Rinse the spot under cool or cold water to dilute what's left. Blot the wet area with a clean cloth, pressing gently instead of rubbing.
Step 3 of 6
Wipe with mild dishwashing liquid
Add a few drops of mild dishwashing liquid to warm water and dip in a soft cloth. Wipe the area gently in small circles until the paste is lifted.
Careful. Check the ingredients for soap. Bar soap and soap-based products can make a tannin stain permanent, so use a detergent-based dishwashing liquid.
Step 4 of 6
Rinse away the soap
Rinse the cloth and wipe the area with plain water until no suds or film remain. Blot it dry with a clean cloth.
Step 5 of 6
Repeat only if a mark remains
If you can still see the mark, repeat the dishwashing-liquid wipe once and rinse again. Stop after that rather than moving on to harsher treatments.
Step 6 of 6
Let the plastic air dry
Once the mark is gone, leave the plastic to air dry at room temperature. Check it in good light before you put it back in use.
Careful. Drying or heating before the mark is gone sets it in place, so wait until the surface is clear.

Amazon Basics Microfiber Cleaning Cloths
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 mark is gone when the surface looks the same as the plastic around it, with no white film or tint when you tilt it toward the light. The area should also feel clean rather than slick, which means the soap has been fully rinsed away.
What changes for yours
Adjust for your plastic & tupperware
Phone case
Take the phone out of the case before you start, so no cleaner gets near it. Wipe the case with a soft, slightly damp, lint-free cloth, and use the dishwashing-liquid wipe only if a mark is left.
Silicone cases need the most care, so keep window cleaners, household cleaners, aerosol sprays, ammonia and solvents away from them. Rinse with plain water afterward and let the case dry fully before you put the phone back in.
Eyeglass lenses
Brush off any dust first so you don't drag grit across the lens. Clean with a lens wipe in small circular movements, and don't use a tissue, tie or sleeve.
If paste is still on the lens after one wipe, repeat with a fresh section of the wipe rather than reaching for another cleaner. Check the lens in good light once it's dry.
Containers and lids
Wash containers and lids by hand in hot soapy water, using a soft cloth on the stained spot. The top rack of the dishwasher is an option only if the product label allows it.
If a faint mark stays after washing, repeat the hot soapy wash rather than using anything harsher. Once it is clean, rinse it and let it air dry.
Plastic toilet seat
Work through the scrape, rinse and wipe order on a plastic toilet seat, using the dishwashing-liquid wipe. Keep nail polish, aftershave and abrasive chemicals off the seat, since they damage the finish.
Rinse with plain water afterward and dry with a soft cloth so the seat isn't left damp. If a mark remains, repeat the wipe once and check the spot in good light.
Acrylic
Acrylic can't take solvents or abrasive cleansers, so the dishwashing-liquid wipe is the only cleaner you need here. Start with the cool rinse and finish with plain water, using a soft cloth throughout.
Skip the solvent options in the remedies below, since they are not safe for acrylic. Check the surface in good light before you stop.
Old, dried or set-in stains
Toothpaste that has sat on plastic for days is harder to lift than a fresh spot. Start with the scrape, then go through the cool rinse and the dishwashing-liquid wipe once more.
If the paste has dried into a crust, let the wiped area sit briefly, then blot it and repeat the wipe. Rinse with plain water each time so no film builds up.
After one more round, a faint mark may still show, and that is the realistic limit on plastic. The plastic can't take abrasive cleansers, solvents or heat, and there is no safe method known for set stains on it. Accept that a light mark may stay rather than pushing harder.
Vinegar, baking soda, peroxide and more
Do home remedies work on toothpaste on plastic & tupperware?

What makes it worse
Mistakes to avoid
Don't scrub with abrasive cleansers
Plastic can't take abrasive cleansers or scrub pads, even on a stubborn mark. A soft cloth and the dishwashing-liquid wipe do the job without damaging the surface.
Don't put lids near a flame or heat
Plastic lids and containers should never go on or under a flame, stovetop or broiler. In the microwave, vent or offset the lid so it doesn't warp.
Don't leave glasses in a hot car
Extreme heat, such as a hot car, is hard on glasses, so keep them out of it while you clean them. Store the lenses somewhere cool once you're done.
Don't overheat fatty or tomato food in plastic
High-fat foods, sugar, oils and tomato sauce can cause staining and blistering when they're overheated in plastic. Keep the heat moderate with those foods so the container stays clear.
When to call a professional
Most toothpaste marks on plastic come off at home with the steps above. If a mark survives repeated rounds, the plastic piece is probably the limit, and it's reasonable to stop rather than push harder.
Questions
Can I use vinegar on plastic to remove toothpaste?
You don't need to. No need for vinegar; mild dishwashing liquid does the job on plastic. Stick with the scrape, rinse and wipe order instead.
Does toothpaste stain plastic permanently?
It can leave a mark if it dries and sits, which is why the steps start with scraping and a cool rinse. Fresh paste usually comes off in one round, while older marks may need one more wipe.
Can I use dish soap on plastic?
Yes, a mild dishwashing liquid in warm water is the cleaner to use. Rinse it off well with plain water, and check the label for soap, which can make a tannin stain harder to remove.
Is rubbing alcohol safe on plastic?
Alcohol is for stubborn marker on plastic lids, not toothpaste, so skip it for this stain. Pretest any alcohol on a hidden spot first.
Will the mark come off with one wipe?
Often the first round of scraping, rinsing and wiping removes most of it. If a faint mark remains, repeat the dishwashing-liquid wipe once before you stop.
Can I use a scrub pad on a stubborn mark?
No, plastic can't take scrub pads or abrasive cleansers, even as a last step. Stop after the repeat wipe instead of moving to anything harsher.
