Mineral deposits from hard water leave ugly stains wherever they build up. Bathtub and shower surfaces are particularly susceptible to calcium deposit stains due to consistent exposure to hard water. Removing calcium deposits and other hard water stains doesn't have to feel like a losing battle. You can get rid of the unsightly white film and scale buildup with supplies found readily around the home. Combine effective supplies with the proper cleaning methods so you can get clean and clear glass shower doors without scratching or damaging the surface.
Cut two lemons in half with a knife. Sprinkle each open half with table salt.
Scrub the surface of the glass shower door with the lemon and salt. Start at the top of the glass door, and work your way down. Squeeze the lemon as you scrub to get juice on the glass. Change to another lemon half as needed.
Leave the lemon juice and salt mixture on the glass surface for 10 minutes.
Wet a paper towel with water, and wring out the towel so it's damp. Wipe the glass shower door to remove the lemon juice and salt mixture.
Dry the shower door surface with paper towels.
Rub an unused dryer sheet over the surface of the shower door. Buff the glass to remove the last traces of calcium deposits and white film.
