Because of the transparency of glassware, keeping drinking glasses clean and spot-free can be a challenge. Dishwashing detergent can leave behind a white filmy residue that, when left to dry, gives the glasses a murky, chalk-like appearance. Use a white vinegar and water cleaning solution—which is safe and effective for removing stains on all kinds of glass—to keep drinkware clear and stain-free.
Collect all of the drinking glasses that contain white film residue. It is easier to clean them all at one time, rather than cleaning them individually.
Set all of the drinkware on your kitchen counter (or another flat surface).
Fill your kitchen sink or water basin with 3 quarts of warm water.
Add 1 quart of white vinegar to the water. Your cleansing solution needs to be 1 part vinegar to 3 parts water, so if you have a small amount of drinkware to clean, such as only a glass or two, then you may substitute 3 quarts of water for 3 cups of water. One quart of vinegar would then be substitute for 1 cup of vinegar.
Mix the cleansing solution and ensure that it is thoroughly stirred.
Place your drinkware into the cleansing solution and leave them to soak for half an hour.
Rinse each glass individually in warm water to ensure that the vinegar solution has been removed from the glasses.
Spread a clean towel on a flat surface (such as a kitchen counter), and place the drinking glasses on the clean towel to dry.
