How to Remove Mineral Deposits from a Glass Shower Door
Mineral deposits on a glass shower door can leave a cloudy, crusty film. Here's a practical, surface-safe guide to remove them without damaging the glass or surrounding fixtures.
Mineral deposits on a glass shower door are a common result of hard water. Over time, calcium and magnesium in the water can dry on the glass, leaving a cloudy, white film that feels rough to the touch. If left untreated, these deposits can become more stubborn and harder to remove. This guide explains how to safely remove mineral deposits from a glass shower door using household ingredients, with steps for both fresh and set-in buildup.

- White vinegar (distilled white vinegar works best)
- Baking soda
- A spray bottle
- A soft sponge or microfiber cloth
- A plastic scraper or old credit card (optional, for stubborn spots)
- Rubber gloves (to protect your hands)
Always test any cleaning solution on a small, inconspicuous area of the glass first to ensure it doesn't cause damage. This is especially important if your shower door has a protective coating or tint.
How to Remove Mineral Deposits from Glass Shower Door
Follow these steps in order for the best results.
- Spray the glass with white vinegar. Fill a spray bottle with undiluted white vinegar and generously coat the affected areas. Vinegar is a mild acid that helps dissolve mineral deposits.
- Let it sit for 10-15 minutes. This allows the vinegar to break down the minerals. For heavy buildup, you can soak paper towels in vinegar and press them against the glass to keep the surface wet longer.
- Scrub gently with a soft sponge or cloth. Use circular motions to lift the loosened deposits. Avoid abrasive scrubbers, which can scratch the glass.
- For stubborn spots, make a baking soda paste. Mix three parts baking soda with one part water to form a thick paste. Apply it to the remaining deposits and scrub gently with a soft cloth or sponge.
- Rinse thoroughly with water. Use a handheld showerhead or a cup of clean water to rinse away all vinegar and baking soda residue.
- Dry the glass with a squeegee or microfiber cloth. This prevents new water spots from forming and leaves the glass streak-free.
