It depends on the structure of the decoration on the cleaning of glass products. Generally, cleaning should be done by hand. Since glass products are very likely to break, good protection is required as much as possible. Glass products can be washed in the dishwasher if they are unpainted. If it is to be washed by hand, some vinegar should be added to the rinse water. If the surface is painted with glass paint (stained glass), it should never be washed in the dishwasher, it should be wiped with a damp cloth without damaging it. Care should be taken not to break it. For cleaning the mirrors, the newspaper paper, which has been turned into a ball, should be immersed in a mixture of 2 parts of water and 1.5 parts of vinegar, and the mirror should be wiped, then dried with a dry cloth. The mirror is rubbed with raw potatoes cut in half and then rinsed with a small amount of alcohol and dried. Alcohol also prevents flies from landing. To use your decorated glass cups in the quality of the first day, be sure to follow the manufacturer's instructions before washing them in the dishwasher.
