First few minutes
Just happened? Do this first
- Lift the liquid off with paper towels pressed onto the spill; avoid rubbing.
- Get cool water on the spot soon after the spill.
- Don't use bar soap or soap flakes on it; natural soap makes tannin stains harder to remove.
- Keep it out of the dryer until the stain is gone.
Tea is a tannin stain, and on glass it shows up as a brown film or ring that gets tougher the longer it dries. Glass handles water well, but a sudden temperature change can crack it, so keep the work cool and steady. Fresh tea often rinses off, while older rings may need a few passes before they fade.
Rinse a glass teapot or pitcher with cool water right after the tea, then wash it with dish soap. Dried tea rings in glass cups and mugs take more passes, so work in small circles with a microfiber cloth. If a brown film in glass pitchers stays after several passes, reach for a gentle glass cleaner instead of harsher scrubbing.

6 steps
Step by step
Step 1 of 6
Blot up the excess tea
Press clean white paper towels or a cloth onto the spill to soak up the liquid. Blot rather than rub, because rubbing spreads the tea over a wider area.
Step 2 of 6
Rinse the spot in cool water
Sponge or rinse the stain in cool water as soon as you can, while the tea is still fresh. Work from the outside edge of the stain toward the middle so it doesn't spread.
Careful. Stick to cool water here; sudden temperature changes can break glass.
Step 3 of 63 to 5 minutes
Wash with dish detergent solution
Mix 1 teaspoon of mild liquid dish detergent into 1 cup of warm water, then wipe the spot with a soft cloth. Leave the solution on heavy build-up for 3 to 5 minutes before you wipe again.
Careful. Check the detergent's ingredient list for soap; bar soap and soap flakes set tea.
Step 4 of 6
Gently scrub with baking soda
Sprinkle baking soda on a damp sponge or cloth and wipe the spot in small, light circles. If the tint is still there, use a non-abrasive cleanser made for glass or ceramic dishware.
Tip. Test any new cleaner on a small, inconspicuous area first.
Step 5 of 6
Rinse the glass thoroughly
Rinse the glass well under clean water after every cleaner you used. Some cleaners need several rinses to clear, so keep going until no film or grit remains.
Tip. Hold the glass up to the light to check for streaks.
Step 6 of 6
Dry and check the spot
Dry the glass with a clean, lint-free towel or let it air dry. Look at it in good light, and if a faint tint remains, go back to the baking soda scrub.

Best products for tea on glass, windows & mirrors
Pick a non-abrasive cleanser made for glass or ceramic dishware, and keep a plastic or nylon pad for any scouring. An enzyme product is only worth buying for an older stain that the steps didn't lift.

How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on glass, windows & mirrors, 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 brown should lift onto the cloth, and the glass should look clear with no cloudy film once it dries. If a faint tint stays after rinsing, the stain is probably older and needs the enzyme soak described below.
What changes for yours
Adjust for your glass, windows & mirrors
Glasses and Glassware
Drinking glasses and stemware take the same steps as any glass, and the tea usually shows as a thin film near the rim. Start with the blot and the cool rinse, then work the dish detergent solution around the rim with a soft cloth.
Stemware has a thin, narrow bowl, so use a folded cloth in small circles rather than a pad. Don't hold the stem and twist the bowl hard, since that puts strain on the join.
Glass Pitchers
Pitchers hold a lot of tea, so the stain often shows as a ring at the waterline. Wash the whole inside with the dish detergent solution, not just the ring, so the color doesn't look patchy.
A narrow pitcher needs a long cloth or a brush with soft bristles to reach the bottom. Rinse the inside until the water runs clear, then leave the lid off to dry.
Glass Teapots
Empty the pot and rinse the inside with cool water first, then wash the spout and the lid area with a soft cloth. Stained tea leaves can cling to a strainer or infuser, so brush it clean as well.
Dry the teapot upside down so no water sits in the spout. Check the spout in good light before you put it away.
Glass Cups and Mugs
Glass cups and mugs take the same steps, and a thin brown line at the rim is the most common mark. Wipe the rim and the inside wall with a soft cloth dipped in the dish detergent solution, then rinse.
Ceramic mugs have their own rules, so use the Dishes & Mugs guide for those. Stick to these steps for clear glass, since decorated glass may need a gentler touch.
Glass Bottles
Narrow bottles trap tea at the bottom and along the neck, so the main job is reaching those spots. Fill the bottle with warm water and a little of the dish detergent solution, then swirl it gently and let it sit briefly.
Use a long, narrow brush or a folded cloth on a stick to reach the neck. Rinse until no cleaner film remains, then drain the bottle upside down.
Old, dried or set-in stains
An older tea stain may respond to a soak in an enzyme product, which is the step to try after the wash above. Soak the glass in the enzyme product, then wash it again with the dish detergent solution and rinse. Old stains are harder to remove than fresh ones, and some won't come out.
If the tea has dried on, soften it with a damp cloth first, then repeat the soak in short passes rather than pressing harder.
Heat sets the stain, so keep the glass out of the dryer and away from heat sources while any tint is left. If the tint is still there after a soak and a repeat, it may be permanent, so stop before trying anything harsher.

Do home remedies work on tea on glass, windows & mirrors?
Many home remedies for tea stains are written for fabric, so most don't belong in a glass routine. Some of these lift tea from glass and some stay out, so check before you use any of them.

What makes it worse
Mistakes to avoid
Don't add liquid to a hot glass
A hot glass or teapot can break if you add cold liquid or set it on a countertop, metal surface or in the sink. Let it cool first, then move it to the sink.
Don't use fluorine-based cleaners
Cleaners with fluorine compounds damage ceramic, glass and stone. Check the ingredient list before you buy a cleaner for glass.
Don't scrub glass with steel wool
Steel wool and other metal or hard objects scratch glass. If scouring is needed, use only a plastic or nylon pad.
Don't let the tea dry on the glass
Old tea stains are harder to remove than fresh ones, and some won't come out. Treat the spill as soon as you see it, even if the glass has been sitting for a while.
When to call a professional
If a valuable piece keeps its tint after the enzyme soak, stop there rather than trying harsher products. A glass or ceramics restorer can tell you whether more work is worth it.
Questions
Does Tea Stain Glass?
Tea can leave a brown tint or ring on glass, especially if it dries on. It's a tannin stain, so the sooner you treat it, the easier it comes off.
Will an old tea stain come out of glass?
A fresh stain usually lifts with the basic steps, but an older one is harder and some won't come out. Try the enzyme soak before you decide it's permanent.
Is vinegar safe for tea stains on glass?
No, vinegar isn't one of the cleaners suited to glassware, so skip it. Stick to the mild dish detergent solution and baking soda.
Can I use bleach on tea-stained glassware?
Skip chlorine bleach on glassware; it isn't suggested for glass. If you're considering it anyway, rinse thoroughly and test a small spot first.
Are tea stains in glass bottles harder to clean?
The narrow neck is the main difference, so the job is reaching the bottom and the neck rather than using different cleaners. Use the same mild detergent solution and rinse until no film remains.
What should I do if I can't wash the glass right away?
Blot up the excess and rinse the glass in cool water so the tea doesn't dry on. Keep it away from heat until it's clean.
