Precautions for cleaning glass products

1.They must be wiped dry after cleaning, otherwise it will leave watermarks. Use a soft towel to wipe along the inner wall of the glassware, and then wipe the outer wall. This can not only avoid the fingerprint residue of fingers, but also avoid the residue of water marks.

2. Clean glass should be placed in a cool and ventilated place. If placed in a confined space, the glass can easily produces a peculiar smell.

3. When we clean the glass, we should pay attention to the material of the glass. For non high borosilicate glass, we must avoid excessive temperature difference. Do not use a glass filled with cold water to directly inject hot water, which is likely to cause cracking.

The above is about how to clean the glass and the precautions when cleaning the glass. When we drink water with a water cup, we must pay great attention to the material of the water cup. Lead free materials shall be selected and try to choose a water cup made of glass, ceramics, crystal ceramics and stainless steel.
