How to Remove Water Stains from Glass Shower Doors
Hard water stains on glass shower doors are caused by mineral deposits — primarily calcium and magnesium — left behind when water evaporates. Toronto tap water is moderately hard, which means these deposits build up steadily. The key to removing them is acid — specifically mild acids that dissolve calcium without scratching or etching the glass.
White Vinegar Method (Mild Stains)
Fill a spray bottle with undiluted white vinegar. Spray generously onto the glass and let it sit for 5–10 minutes. The acetic acid dissolves light calcium deposits on contact. Scrub with a non-scratch sponge using circular motions, then rinse with water and squeegee dry. For stubborn spots, soak a cloth in vinegar, press it against the stain, and leave for 20–30 minutes before scrubbing.
Baking Soda Paste (Moderate Stains)
Mix baking soda with just enough water to form a thick paste. Apply to the stained areas and scrub with a non-scratch sponge — the mild abrasive action of baking soda combined with its alkalinity helps lift scale that vinegar alone cannot remove. Rinse well. For extra power, apply vinegar on top of the baking soda paste and let the fizzing reaction work before scrubbing.
Commercial Descaler (Heavy Buildup)
Products like CLR (Calcium, Lime & Rust Remover) or Bar Keepers Friend are formulated specifically for mineral deposits. Apply with a damp cloth, work in sections, and rinse thoroughly — do not let them dry on the glass. These are more aggressive than vinegar and should not be used on coated glass or framed tracks without checking the manufacturer's guidance.
Preventing Future Buildup
- Squeegee the glass after every shower — this single habit prevents 90% of buildup
- Apply Rain-X or a dedicated glass treatment every few months — hydrophobic coatings cause water to bead off
- Spray with diluted vinegar weekly as part of your bathroom routine
