There are several ways to effectively clean drinking glasses with everyday household products. Wash glasses regularly with warm water and a minimal amount of dish soap, and allow the glasses to air dry. If you use a dishwasher, opt for a gentle cycle and space out the glasses to avoid damage. Use a vinegar solution to clean cloudy residue or streaks. For dark stains, try a bleach and water soak, or use plain toothpaste to gently scrub your glasses.
