- Rinse the spot promptly in cool water.
- Check the spot in good light before you put the piece away.
Tea is a tannin stain, and on plastic it's easiest to lift when you catch it early. Cool water and a little mild dishwashing liquid handle fresh marks well. Set-in marks are the hard part, and there's no dependable home method for them on plastic, so some may stay.
Tea stains on plastic cups and containers respond best to a quick wipe while the tea is still wet. Tea stains on a plastic jug or bottle need the same gentle approach, just with a little more patience. If a mark still shows after a few tries, stop rather than scrubbing harder, because scratches can hold more stain.

6 steps
Step by step
Step 1 of 6
Blot up the excess
Press clean white paper towels or a cloth onto the tea to soak up as much as you can. Don't rub, because that spreads the tea across the plastic. Work quickly while the liquid is still wet.
Step 2 of 6
Rinse the spot in cool water
Sponge the stain with cool water, or hold the piece under a gentle stream from the tap. Start at the outer edge and work toward the middle so the tea doesn't spread. Fresh tea lifts far more easily than tea that has dried.
Step 3 of 6
Wash with mild dishwashing liquid
Add a few drops of mild dishwashing liquid to warm water and wipe the stained area with a soft cloth. Rinse the cloth often and keep wiping until no tint shows on it.
Careful. Don't use bar soap or soap flakes; natural soap makes tannin stains harder to remove.
Step 4 of 6
Hand-wash containers in hot soapy water
For containers, fill the sink with hot soapy water and let the piece soak briefly before washing it by hand. If the product allows it, the dishwasher top rack is the only other option. Rinse everything clean before you check it.
Step 5 of 6
Gently wipe away any leftover stain
If a shadow remains, rub gently with a soft cloth and the same dishwashing liquid water. Stop as soon as the cloth picks up nothing more. Press lightly rather than grinding at the spot.
Step 6 of 6
Dry and inspect the piece
Dry the piece with a clean towel and look at the spot in daylight or a bright light. If a faint tint is still there, it has set in, so move on to the stronger option below.

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 stain is gone when the spot looks the same as the plastic around it in good light. A faint tint that stays after drying usually needs the stronger option, not more scrubbing.
What changes for yours
Adjust for your plastic & tupperware
Cups, mugs and glasses
Cups, mugs and glasses are usually washed by hand, so the dishwashing liquid and warm water do most of the work. Plastic glasses are thin and show scratches, so wipe them with a soft cloth rather than scrubbing.
Work the cloth around the rim and along the inside wall, since tea collects there, and check the rim in good light before you put it away. If your drinking glasses are actually glass rather than plastic, the Glass, Windows & Mirrors guide covers them.
Plastic containers
Food containers are the main case for hot soapy water, so fill the sink and wash the container and lid by hand. Separate the lid from the base so the seal and rim get cleaned too.
The dishwasher top rack is the only other option, and only if the product allows it. Let all the parts dry fully before you snap the lid back on.
Jugs and bottles
A jug's wide opening lets you reach the inside with a soft cloth and warm dishwashing liquid water. A bottle's narrow neck is harder, so pour warm water and a few drops of dishwashing liquid in, cap it and shake gently.
Rinse well with clean warm water afterward, looking for a tint along the bottom and near the neck where tea pools. If a faint tint remains, repeat the soapy rinse before you move on.
Clear plastic
If the clear piece is acrylic, solvents and abrasives can damage it. Wash it with warm water and a few drops of mild dishwashing liquid on a soft cloth.
Skip isopropyl alcohol on acrylic, even for a stubborn spot, and pat it dry rather than rubbing. Check it in good light before deciding whether the stain has set in.
Plastic thermos
A thermos is hard to reach inside, so don't force a cloth into a space you can't see. Fill it with warm water and a little mild dishwashing liquid, then swirl and empty it.
Rinse several times with clean water until no soap or tint remains. If the inside is still stained, use the stronger option and check the manufacturer's care instructions for the liner.
Iced tea
Iced tea leaves the same tannin stain as hot tea, so the same order of steps applies. Rinse the pitcher or cup as soon as it's empty, before the tea has a chance to dry in.
Pay extra attention to the waterline inside the pitcher, where the tea dries and leaves a ring. Wipe that band with the dishwashing liquid cloth before you rinse the rest.
Old, dried or set-in stains
An old tea stain has had longer to settle into the plastic, so one wash may only lighten it. Repeat the dishwashing liquid wash, letting the soapy cloth rest on the spot before you wipe.
For containers, repeat the hot soapy water soak, then rinse thoroughly before you check the spot. Tea that has dried may need several rounds, so rinse between each one.
Some stains won't come out, and that's the realistic result for old tea on plastic. Stop when more rubbing only wears the surface, and accept a faint tint as the limit.

Do home remedies work on tea on plastic & tupperware?
Most home remedies are written for fabric, so few of them carry over to plastic. Mild dishwashing liquid and warm or hot water are all that plastic needs. The remedies below don't suit plastic, so skip them.

What makes it worse
Mistakes to avoid
Don't put a plastic lid near a flame
Plastic lids and containers shouldn't go on or under a flame, stovetop or broiler, or near any direct heat. Heat can warp them, so keep them clear of cooking surfaces while you clean.
Don't microwave with lids sealed
Vent the lid or set it slightly off the container. A sealed lid can warp, and a warped lid won't seal properly again.
Don't scrub with abrasives
Abrasive cleansers and scrub pads scratch the surface and can leave it dull. Stick with a soft cloth and the dishwashing liquid water instead.
Don't let the tea dry on the plastic
Blot and rinse the spot as soon as you can, before it dries. Waiting turns a simple rinse into a job that needs the stronger option.
When to call a professional
There's no clear point where a professional becomes the right call for plastic. If the stain stays after the stronger option, or the piece is clouded or scratched, replacing it is safer than scrubbing harder.
Questions
Can I put a tea-stained plastic container in the dishwasher?
Only on the top rack, and only if the product allows it. Hand washing in hot soapy water is the safer default, so start there.
Why does my plastic cup still look tinted after washing?
A faint tint usually means the stain has had time to settle, which makes it harder to lift in one wash. Repeat the dishwashing liquid wash, then check the rim in good light before trying the stronger option.
Is iced tea harder to remove than hot tea?
Iced tea is the same tannin stain as hot tea, so the same steps work. The real difference is how long it sits, so rinse the pitcher as soon as it's empty.
Can I use rubbing alcohol on a plastic pitcher?
No, leave it out. Acrylic can't take it, and mild dishwashing liquid with warm water is the safe choice for a plastic pitcher.
Does the same method work on clear plastic?
Yes, with warm water and mild dishwashing liquid applied with a soft cloth. If the clear piece is acrylic, though, skip solvents, abrasives and alcohol.
How do I clean the inside of a plastic thermos?
Work from the inside with a soft cloth you can reach, since the lower walls are hard to see. Then rinse until the water runs clear, and check it in good light.
Why won't my old tea stain on plastic come out?
Old stains are harder to remove than fresh ones, and some won't come out at all. Try the stronger option once, then accept the result rather than scrubbing harder.
