How to clean stainless steel tea filter screen

Stainless steel tea filters can be soaked in white vinegar or wiped with baking soda paste, and stubborn tea stains can be boiled and cleaned with citric acid solution. Timely rinsing after daily use can extend the lifespan of the filter and prevent alkaline cleaning agents from corroding metal surfaces.

Stainless steel tea filter screen is prone to accumulate tea stains in long-term contact with tea soup, mainly composed of tea polyphenol oxides and mineral deposits. Acetic acid in white vinegar can dissolve alkaline tea stains. Soak the filter in a 1:1 white vinegar solution for half an hour and then wipe it with a soft cloth. Baking soda paste is made by mixing baking soda with a small amount of water to form a paste. After dipping it in an old toothbrush and brushing the mesh gaps, its micro particle friction can remove attachments without damaging the metal. For severely sintered tea stains, a 5% solution of food grade citric acid can be boiled for 3 minutes. Organic acids can completely decompose stubborn deposits at high temperatures.

In special circumstances, rust spots on the filter screen need to be treated differently. Food grade stainless steel is usually made of 304 or 316 material and should not rust during normal use. If the protective layer is damaged due to collision, toothpaste can be used in conjunction with nano sponge polishing to restore a smooth finish. Poor quality chrome plated filters may experience coating detachment, and it is recommended to replace them with food grade stainless steel products. After cleaning, rinse off any residual cleaning agents with boiling water, then invert and dry to prevent water retention and bacterial growth.

It is recommended to thoroughly clean the stainless steel tea filter once a week, and immediately rinse both sides with running water after daily use. When storing, avoid collision with hard objects and hang it in a well ventilated place to keep it dry. Choosing a filter with moderate mesh density can reduce the blockage of tea leaves, and tapping the edge of the filter gently after brewing can help the residue fall off. If the filter screen is found to be deformed or cracked at the welding point, it should be replaced in a timely manner to avoid scratching the metal sharp edges or affecting the filtering effect.
