How to avoid tea stains in the thermos cup? What are the ways to avoid tea stains in the thermos cup? Nowadays, we are all using stainless steel vacuum flasks provided by vacuum flask manufacturers, but can’t vacuum flasks be used to make tea? Do you know why? Since it is often used to brew tea in a thermos cup for a period of time, a layer of dirty tea stain will accumulate, and it is not easy to clean, originally there is no fragrance that should be due to tea in a high-temperature cup. If the tea is dirty, it will not only be unsanitary, but will also shorten the life of the vacuum flask.

The reason why a thermos cup is not suitable for making tea affects the taste of the tea itself and loses its health care effect. Since the temperature of the thermos cup is usually relatively high, although the tea can be quickly dissipated, it also reduces the fragrance that the tea should have. In addition, tea leaves that have been blanched at high temperatures will lose their rich nutrients, and then lose the health benefits of the tea. Therefore, it is not suitable to use a thermos cup for making tea. Here we remind those friends who often use the thermos cup to make tea, in order not to affect the insulation effect of the thermos cup and the tea stains in the cup, please avoid using the insulation cup to make tea.
