How to Clean a Tea Infuser and Remove Teapot Stains
Share
A new mesh infuser is shiny and fine enough to hold rooibos dust. A few months later it is brown, half clogged, and your tea drains slowly and tastes a little stale. Learning how to clean a tea infuser properly takes five minutes and things you already own: hot water, baking soda, a soft brush and sometimes white vinegar or citric acid. This guide covers each type of infuser and teapot, what causes the stains, and the few materials that need special care.
Key takeaways
- Rinse infusers right after use and tap out the leaves; most stains come from leaves drying in the mesh.
- Brown tea film lifts with a baking soda paste or a soak in hot water and baking soda.
- White, chalky deposits are limescale; dissolve them with diluted white vinegar or citric acid.
- Unglazed clay and cast iron teapots should not be scrubbed with soap or abrasives.
Why tea stains infusers and teapots
Two different deposits build up, and they need different fixes:
| What you see | What it is | What removes it |
|---|---|---|
| Brown or orange film, sticky feel | Tea residue: compounds from the leaf that cling to surfaces as they dry | Baking soda (mildly alkaline and gently abrasive) and a soft brush |
| White, chalky or rough spots | Limescale from hard water | Mild acid: diluted white vinegar or citric acid |
| Clogged mesh | Tiny leaf particles trapped in the weave | Soaking, then brushing from the outside in |
| Musty smell | Leaves or moisture left inside | Thorough drying with the lid off |
If you are not sure which you have, try baking soda first. If the spot will not budge, it is probably limescale.
How to clean a tea infuser, by type
Stainless steel mesh baskets and balls
- Tap out the leaves into the compost and rinse under hot running water, spraying from the outside so trapped particles push back through.
- For brown film, fill a bowl with hot water and add 1 tablespoon (about 15 g) of baking soda per 2 cups (500 ml). Soak the infuser 15–30 minutes.
- Scrub gently with a soft toothbrush, again from the outside in. Do not use steel wool on fine mesh; it can tear or stretch it.
- For white limescale, soak in 1 part white vinegar to 3 parts warm water for 15–20 minutes, or dissolve 1 teaspoon of citric acid in 2 cups (500 ml) of warm water.
- Rinse very well and dry with the lid open.
Silicone infusers
Silicone can hold onto smells as well as color. Wash in hot soapy water, then soak in a baking soda solution. For stubborn odors, a paste of baking soda and a little water left on for an hour helps. Rinse thoroughly. Many silicone infusers are dishwasher-safe; check the maker’s instructions.
Plastic and nylon mesh
Use warm, not boiling, water and a soft brush. Skip strong acids and abrasive pastes, which can scratch or cloud plastic. Replace these when the mesh discolors permanently or starts to fray; they are inexpensive.
Paper and cloth filters
Paper tea filters are single-use. Reusable cotton tea socks should be rinsed after each use, boiled in plain water occasionally, and dried fully to prevent mildew. Skip scented detergent, which tea will taste of.
How to remove stains from teapots
| Teapot | Safe cleaning | Avoid |
|---|---|---|
| Glazed ceramic or porcelain | Baking soda paste, soak in hot water with baking soda, mild dish soap | Bleach-based cleaners left to sit |
| Glass | Baking soda soak; vinegar or citric acid for cloudiness | Sudden temperature shocks (cold water into a hot pot) |
| Stainless steel | Baking soda paste; vinegar or citric acid for scale | Steel wool on polished surfaces |
| Enameled cast iron | Rinse with warm water, soft cloth, dry immediately | Soap, abrasives, dishwasher, leaving water standing |
| Unglazed clay | Rinse with hot water only and air-dry | Soap and detergents, which the clay can absorb |
The baking soda method for ceramic and glass
- Sprinkle 2 tablespoons of baking soda into the empty teapot.
- Add just enough hot water to make a loose paste and rub the stained areas with a soft sponge or bottle brush.
- For heavy stains, fill the pot with hot water instead and leave the baking soda solution to soak for an hour or overnight.
- Clean the spout with a pipe cleaner or a small bottle brush; it is where residue hides.
- Rinse twice and dry with the lid off.
Mugs stained by tea and coffee respond to the same treatment. Our guide to cleaning coffee-stained mugs covers that in more detail.
A simple cleaning routine
| When | What to do | Time |
|---|---|---|
| After every use | Empty leaves, rinse with hot water, dry open | 1 minute |
| Weekly | Baking soda soak and soft brush | 20 minutes, mostly waiting |
| Monthly (hard water) | Vinegar or citric acid soak for limescale | 20 minutes |
| When smells linger | Baking soda paste for an hour, then rinse | 1 hour |
Tips that prevent stains
- Empty the infuser immediately. Leaves left to dry are the main cause of brown mesh.
- Use one infuser for strongly flavored teas such as smoky, spiced or bergamot blends, and another for delicate greens and herbals, so flavors do not carry over.
- Do not leave tea standing in the pot overnight.
- Filter hard water if limescale keeps coming back; it also improves the taste of tea and coffee.
- Choose a roomy infuser. Leaves need space to unfurl; a cramped ball both brews poorly and clogs faster.

Ready for a clean brew
A clean infuser makes the biggest difference with fragrant teas. Try our Earl Grey, Ceylon black tea with bergamot oil and cornflowers, in a dedicated infuser so the bergamot does not perfume your other teas. For a caffeine-free evening cup, Chamomile Ginger pairs chamomile with warming ginger and lemon, and Hibiscus Berry is fruity and deep red, a tea that stains readily, so rinse right after.

Tea infuser cleaning FAQ
Can I put a tea infuser in the dishwasher?
Many stainless steel and silicone infusers are dishwasher-safe, but fine mesh can still trap particles. Check the maker’s instructions and rinse out leaves first.
Does vinegar remove tea stains?
Vinegar is best for white limescale. For brown tea film, baking soda works better. Rinse well after either.
How do I unclog a mesh tea strainer?
Soak it in hot water with baking soda, then brush from the outside in with a soft toothbrush so particles exit the way they came.
Should I use soap on a teapot?
On glazed ceramic, glass and steel, mild dish soap is fine if you rinse well. Avoid soap on unglazed clay and enameled cast iron.
