How to maintain the double-layer glass?

1. Wash the double cup with a soft cloth and warm water, it is also good for our health to keep it clean and tidy before and after use.

2. When there is residual dirt in the glass, soak it in warm water for a period of time until the dirt becomes soft, then wash it. Do not scratch the glass with rough objects, especially metal cleaning balls, as these objects will leave scratches on the glass body, affecting the transparency and aesthetics of the glass.

Do not pour too much boiling water into the glass. Too full is not conducive to drinking and may cause burns. In addition, if you use a double-lid cup when drinking water, if the position is too high, the sealing ring with the lid will be immersed in boiling water. Long-term use will affect the sealing performance and service life of the sealing ring. Tighten the lid too tightly.
