How do I remove hard water stains from glass shower doors?

White vinegar and dish soap are your most effective weapons against hard water stains on glass shower doors. Mix equal parts white vinegar and warm water in a spray bottle, add a few drops of dish soap, and spray the entire surface. Let it sit for 10-15 minutes before scrubbing with a non-abrasive sponge.

For stubborn buildup common in Ottawa's hard water areas, create a paste using baking soda and water. Apply this paste to the worst stains, let it sit for 20 minutes, then scrub gently with a soft brush or sponge. The mild abrasive action helps break down mineral deposits without scratching the glass. Rinse thoroughly with warm water and dry with a squeegee or microfiber cloth to prevent new water spots.

Commercial lime and calcium removers like CLR work well for severe buildup, but always test in an inconspicuous area first. These products are stronger than natural solutions but require good ventilation and careful handling. Follow the manufacturer's instructions exactly, as leaving these products on too long can damage door seals or hardware.

Ottawa's municipal water has moderate hardness levels, so regular maintenance prevents heavy buildup. Daily squeegeeing after showers and weekly cleaning with the vinegar solution keeps doors crystal clear. Consider applying a glass treatment product like Rain-X every few months - it creates a protective barrier that makes water bead up and roll off, reducing future staining.

For doors with years of neglect or etching from harsh cleaners, the glass may need professional restoration or replacement. If you're planning a shower renovation, frameless glass doors with protective coatings are easier to maintain than framed units with metal tracks that trap soap scum.
