A tea strainer looks small and simple, but its fine mesh traps tannins, mineral deposits, and dried tea leaves that ordinary rinsing never reaches. Left untreated, those build-ups stain the steel, narrow the mesh holes, and eventually taint the flavour of every cup that follows. The video above shows the process in real time; the steps below walk you through everything — from a quick daily rinse to a deep soak — so your strainer stays clean whether you are running a household, a holiday rental kitchen, or a hotel breakfast service in Greece.
Why Tea Strainers Get So Dirty So Fast
Black tea, mountain herb tea (tsai tou vounou), and Greek mountain tea all release tannins — the same plant compounds that stain teeth and teapots. When hot liquid passes through the mesh, tannins bond to the fine steel wires within seconds. Over multiple uses, this brownish film hardens into a lacquer-like coating that regular dish soap can barely touch.
Hard water — common in many parts of Greece — adds a second layer of trouble. Calcium and magnesium ions left behind after each rinse form a chalky white crust that physically blocks the mesh holes and forces you to pour slower or wait longer for your tea to drain.
Choosing the Right Cleaning Method
The method you need depends on how long the residue has been sitting. For a strainer used and rinsed daily, a one-minute soak in hot soapy water followed by a soft brush is almost always enough. For a strainer that has been sitting in a drawer for weeks, or one handed down through a rental apartment without proper care, a baking soda and white vinegar soak will dissolve both the tannin layer and the mineral scale in a single session.
Avoid steel wool, harsh abrasive pads, or bleach on stainless steel mesh. Steel wool leaves micro-scratches that trap more residue next time, and bleach can pit the metal and leave a taste that ruins even premium tea.
How to Deep-Clean a Tea Strainer: 5 Steps
- 1
Knock out loose leaves and rinse under hot running water
Hold the strainer upside down and tap it firmly against the inside of the sink to dislodge any stuck leaves. Then rinse both sides under the hottest tap water available for about 30 seconds. This removes loose solids and softens the tannin film before you add any cleaning agent.
- 2
Make your soaking solution
Fill a small bowl or mug with 250 ml of just-boiled water. Add one tablespoon of baking soda and stir until mostly dissolved. For heavier staining or mineral scale, also add two tablespoons of white wine vinegar — the fizzing reaction lifts deposits from the metal surface. Use a glass or ceramic bowl rather than a metal one so you can see the colour change as tannins release into the water.
- 3
Soak the strainer for 5 to 10 minutes
Submerge the strainer completely, making sure the mesh is fully below the surface. Let it sit for at least five minutes. You will see the water turn brown as tannin compounds detach from the mesh. For heavily stained strainers — especially those from rental kitchens that have not been deep-cleaned in months — extend the soak to ten minutes or until the water stops darkening.
- 4
Scrub with a soft brush and rinse thoroughly
Use an old toothbrush or a dedicated small cleaning brush to work across both sides of the mesh with light circular strokes. Pay extra attention to the rim joint where the mesh meets the metal frame, as residue concentrates there. Rinse under hot running water again, flipping the strainer back and forth, until the water runs completely clear and you can see light through every part of the mesh.
- 5
Dry completely before storing
Shake off excess water and set the strainer on a clean dish towel or a drying rack in an open position. Never store it in a closed drawer while still damp — trapped moisture leads to rust spots on the joint seam even on stainless steel. If you are preparing a rental apartment for guests, a fully dry strainer also signals cleanliness and attention to detail that visitors notice and appreciate.

FAQ
- How often should I deep-clean a tea strainer?
- For daily household use, a thorough soak once a week is enough to prevent tannin build-up. In a holiday rental or hotel setting where multiple guests use the strainer back to back, clean it at every turnover — ideally the same session as the kettle and mugs.
- Can I put a tea strainer in the dishwasher?
- Many stainless steel strainers are technically dishwasher-safe, but the high heat and harsh detergent tablets can loosen the solder or crimp where the mesh meets the handle over time. Hand-washing with the baking-soda soak takes less than ten minutes and extends the strainer's life considerably.
- The mesh holes are still blocked after soaking — what now?
- Repeat the baking-soda soak with freshly boiled water and leave it for 20 minutes. If scale is the problem (white or grey deposits rather than brown staining), use undiluted white vinegar instead of the water-baking-soda mix — pure acid dissolves calcium carbonate faster. A toothpick can clear individual holes without damaging the mesh wires.
