Is it possible to remove scratches from the crystal glasses and other products?

It depends on the specific product. Scratches on thin-walled products (e.g., glasses) are difficult to fix, given that they don’t have a sufficiently thick layer of crystal to sand away. On the other hand, decorative objects and thick-walled drinkware glass can be sanded or polished, thus removing any scratches. This same method is used to repair a product’s damaged base.
