How to Remove Hard Water Stains from a Glass Shower Door

1. Mix a cleaning solution. In a spray bottle, combine equal parts white vinegar and water. For heavy buildup, use undiluted white vinegar.
2. Spray the stained areas. Generously spray the vinegar solution onto the glass, covering all spots.
3. Let it sit. Allow the solution to sit for 5 to 10 minutes. This gives the vinegar time to dissolve the mineral deposits.
4. Scrub gently. Use a soft sponge or non-abrasive scrub pad to gently scrub the glass in circular motions. Avoid steel wool or harsh scouring pads, as they can scratch the glass.
5. Rinse thoroughly. Rinse the glass with clean water to remove any remaining vinegar and loosened minerals.
6. Dry the glass. Use a clean microfiber cloth or a squeegee to dry the glass completely. This prevents new water spots from forming.

Removing Stubborn, Set-In Stains

If the stains are older or more severe, you may need a stronger approach. Baking soda can provide extra abrasion without scratching the glass.

1. Make a paste. Mix baking soda with a small amount of water to form a thick paste.
2. Apply the paste. Spread the paste over the stained areas using a soft cloth or sponge.
3. Let it sit. Allow the paste to sit for 10 to 15 minutes.
4. Scrub gently. Gently scrub the paste into the stains with a soft cloth or non-abrasive pad.
5. Rinse and dry. Rinse the glass thoroughly and dry it with a squeegee or microfiber cloth.

What Not to Do

• Avoid harsh chemicals. Do not use bleach, ammonia, or other strong cleaners, as they can damage the glass or surrounding materials.
• Avoid abrasive tools. Steel wool, metal scrapers, and harsh scouring pads can scratch the glass permanently.
• Do not mix vinegar and bleach. Mixing these can produce toxic fumes.

Fresh vs. Dried Stains

Fresh water spots are easier to remove and may only require a quick wipe with a vinegar solution. Dried, set-in stains need more time and effort. For dried stains, you may need to repeat the vinegar treatment or use the baking soda paste method. In extreme cases, a commercial glass cleaner designed for hard water stains may be necessary.
