In daily life, when we drink water , we use a glass. Glasses are usually made of raw borosilicate glass, fired at a high temperature of more than 600 degrees. However, when glasses are used for a long time, It will become blurry and opaque. If these conditions occur, your glasses need cleaning.
1. Use a kitchen cleaner
First soak it with a kitchen cleaner. After the cleaning agent is washed, the glass will be as bright as new.
2, vinegar
If the cup is still not shiny, It means the cup has scale attached. You can add half vinegar and half of the water for a few hours to the cup. If there is a lot of scale, you can use only vinegar.
3. Use alcohol
Pay attention to 75% of medical alcohol. Pour about 15ml of alcohol into the clean cloth, carefully scrub the inner wall of the glass, and rinse it with water.
