Removing Hard Water Stains from Glassware

Mix 2-3 tablespoons of baking soda with just enough water to form a thick paste. Apply the paste to the stained areas of the glass and gently scrub with a soft cloth or sponge using circular motions. Rinse thoroughly with clean water and dry.

Fill a basin or sink with equal parts white vinegar and warm water, then submerge the stained glassware for 30-60 minutes. For heavier buildup, use undiluted vinegar. After soaking, scrub lightly with a soft sponge and rinse thoroughly with clean water.

Cut a lemon in half and rub it directly over the hard water stains on the glass, squeezing gently to release juice onto the mineral deposits. Let the juice sit for 5-10 minutes, then scrub with a soft cloth and rinse with clean water.

Apply a commercial hard water stain remover such as CLR, Bar Keepers Friend, or Bio-Clean directly to the affected glassware following the product label instructions. Most products require spraying or wiping the solution on, waiting a few minutes, then rinsing clean.

After washing glassware normally, give each piece a final rinse with distilled water before placing it on a drying rack or towel-drying. This removes any mineral-laden tap water from the surface before it can evaporate and leave deposits.
