Every chai channi goes through the same thing: the mesh slowly clogs with tea dust, turns brown or black, and the chai starts pouring slowly. The good news is that a stainless steel strainer can almost always be brought back to looking new with things already in your kitchen.
Why does a chai channi turn black?
Tea contains tannins, and milk leaves a film of fat and protein. Every cup leaves a thin layer on the mesh. Over days this layer darkens and blocks the tiny holes. Masala chai adds fine spice particles that get stuck in the weave.
Everyday cleaning (30 seconds)
- Tap out the leaves straight after pouring.
- Rinse from the back under running water. This pushes particles out the way they came in.
- Shake dry and leave it to air-dry.
Doing this every time stops most build-up before it starts.
Deep cleaning a black or blocked channi
Method 1: Baking soda paste (for brown stains)
Mix 1 tbsp baking soda with a little water into a thick paste. Rub it into the mesh with an old toothbrush, from both sides. Leave for 10 minutes, then scrub and rinse from the back.
Method 2: Hot water, baking soda and vinegar soak (for heavy build-up)
Put the channi in a bowl. Add 1 tbsp baking soda, pour over hot water, then add 2 tbsp vinegar and let it fizz. Soak for 20–30 minutes, then scrub with a toothbrush and rinse from the back.
Method 3: Lemon and salt (for daily shine)
Rub half a lemon dipped in salt over the mesh, leave for 5 minutes and rinse.
Method 4: Boil it (for a fully clogged mesh)
Boil the channi in water with 1 tsp baking soda for 5–10 minutes. Let it cool, scrub gently and rinse. Only do this with an all-metal strainer. Never boil one with a plastic or wooden handle.
What to avoid
- Steel wool or knives on the mesh: they tear and stretch the weave, and the holes get bigger.
- Bleach: it can discolour steel.
- Burning the mesh on the gas flame: a common hack, but it weakens and discolours fine mesh over time.
When is it time for a new one?
Replace it if the mesh is torn or stretched (leaves slip through), the frame has come loose from the handle, or it has rust spots that come back after cleaning.
A channi that's easier to keep clean

Its herringbone-weave mesh catches fine tea dust while letting chai flow through quickly, and it rinses clean from the back in seconds. It's dishwasher safe, though hand washing is recommended.
