Hard water stains on glass shower door — Madrid, Madrid
White, hazy, or chalky deposits on a glass shower door are mineral scale — primarily calcium carbonate and magnesium — left behind when hard water evaporates on the surface. Over time, untreated deposits etch into the glass, progressing from a surface film that wipes off with vinegar to a chemical bond that no household cleaner can remove. Professional deep cleaning addresses hard water stains using commercial-grade acidic cleaners (phosphoric or hydrochloric acid formulations), non-scratch abrasive pads, and diamond polishing compounds for etched glass. A cleaner can also apply a hydrophobic glass coating after restoration that causes water to bead and sheet off, dramatically slowing future buildup.
