How to avoid tea stains from thermos cups? What are the methods to avoid tea stains from thermos cups? Nowadays, we are all using stainless steel insulated cups provided by insulated cup manufacturers, but insulated cups cannot be used to make tea? Do you know why? Due to the frequent accumulation of dirty tea stains after brewing tea in a thermos cup for a period of time, and the difficulty of cleaning, using a high-temperature cup to brew tea does not have the fragrance that tea should have. If tea stains accumulate layer by layer for a long time, it will not only be unhygienic, but also shorten the lifespan of the thermos cup.

The reason why it is not advisable to use a thermos for brewing tea is that it affects the taste of the tea itself and loses its health benefits. Due to the high temperature of the thermos, although tea can quickly dissipate, it also reduces the fragrance that tea should have. Moreover, tea leaves that have been scalded at high temperatures will lose their rich nutrients and lose their health benefits, so it is not suitable to use a thermos cup for brewing tea. We would like to remind friends who often use insulated cups to brew tea. In order to avoid affecting the insulation effect of insulated cups and the tea stains in the cups, please avoid using insulated notebooks to brew tea.
