How to Remove Mineral Deposits From Drinking Glasses

Hard water can coat your dishes in lime scale, which is a buildup of mineral deposits. The calcium and magnesium spots on drinking glasses are difficult to remove with regular dish detergent, and use of a dishwasher may worsen the problem. The heat from a dishwasher triggers a rapid release of minerals from the water, which increases the amount of spots and filmy residue on drinking glasses, according to Remove mineral spots from glasses with ingredients commonly found in the kitchen.
