How to Remove Hard Water Stains from Glass, Tile, and Fixtures
Proven methods to remove white mineral deposits from shower doors, faucets, and tile.
What creates those white spots
Hard water stains are calcium carbonate and magnesium deposits left behind when water evaporates. They appear as white, chalky film on glass shower doors, cloudy spots on faucets, white rings around drains, and haze on tile. The longer they sit, the harder they are to remove because the minerals chemically bond to surfaces.
Removal methods by surface
Glass shower doors: White vinegar spray (let sit 15 min, scrub with non-scratch pad). For severe buildup, use a paste of baking soda and vinegar or a commercial product with phosphoric acid. Chrome/stainless fixtures: CLR or Bar Keepers Friend applied with a soft cloth. Never use abrasive pads on finishes. Tile and grout: Vinegar solution or a steam cleaner. Toilet bowl: Pumice stone (wet first to avoid scratching) or hydrochloric acid-based bowl cleaner.
Prevention
Removing stains is a recurring battle unless you address the source. A water softener eliminates new mineral deposits entirely. A salt-free conditioner reduces but does not eliminate spotting.
