Excuse me, who can tell me how to remove the tea dirt from the glass?

There are many kinds of stainless steel stains, and each removal method is different. You must find the reason first and you'd better deal with it now. (1) Remove the tea scale on the metal tea partition. When using metal tea partition, it will turn black due to tea dirt. If it can't be washed off with a medium-sized cleaner, it can be soaked in vinegar or easily cleaned with bleach. (2) Remove tea stains from teacups or teapots. If teacups and teapots are used for a long time, there will be many tea stains, which can be easily removed by wiping them with a sponge dipped in salt. (3) Except for small pieces of tea dirt, it can be soaked in the solution of bleach or cleaning powder and left overnight to remove the tea dirt. (4) Can be scrubbed with toothpaste or broken egg shells, and then rinsed with clear water.
