How to Remove Hard Water Spots from a Glass Shower Door

1. Mix equal parts white vinegar and water in a spray bottle. For very stubborn spots, you can use full-strength vinegar.
2. Spray the solution generously onto the glass, covering all the hard water spots.
3. Let it sit for 5 to 10 minutes. This gives the acid time to break down the minerals.
4. Scrub gently with a soft sponge or a non-abrasive pad. For tough spots, you can use an old toothbrush to work the solution into the deposits.
5. Rinse thoroughly with clean water.
6. Dry the glass with a squeegee or a clean microfiber cloth to prevent new spots from forming.

If the spots are particularly stubborn, you may need to repeat the process or use a paste of baking soda and water as a gentle abrasive.

Method 2: Baking Soda Paste

Baking soda is a mild abrasive that can help lift mineral deposits without scratching the glass. Here's how to make and use a paste:

1. In a small bowl, mix 1/2 cup of baking soda with 3 tablespoons of water to form a thick paste.
2. Apply the paste to the hard water spots using a soft cloth or sponge.
3. Gently rub the paste into the spots in a circular motion. Be careful not to press too hard.
4. Let the paste sit for 5 to 10 minutes.
5. Rinse thoroughly with water.
6. Dry the glass with a squeegee or microfiber cloth.

This method works well for dried, set-in spots that vinegar alone might not remove.

What Not to Do

Avoid using harsh chemicals like bleach or ammonia, as they can damage the glass or any coatings. Also, steer clear of abrasive scrubbers like steel wool or scouring pads, which can leave scratches. Never use a razor blade or scraper on glass unless you're experienced, as it's easy to scratch the surface.
