How to Remove Hard Water Stains from a Glass Tile Shower Wall

Step-by-Step Method for Dried or Stubborn Stains

For older, crusty deposits, you'll need a bit more effort:

1. Make a paste by mixing baking soda with a small amount of water until it forms a thick spreadable consistency.
2. Apply the paste to the stained areas, covering them completely. Let it sit for 15–20 minutes.
3. Gently scrub with a soft sponge or cloth, using small circular motions. The baking soda acts as a mild abrasive to lift the minerals.
4. Rinse thoroughly with warm water, making sure all paste is removed.
5. If stains persist, repeat the process or try the vinegar soak method below.

Alternative: Vinegar Soak for Heavy Deposits

For very stubborn spots, you can use a vinegar-soaked cloth:

1. Soak a clean cloth in white vinegar and lay it over the stained area.
2. Let it sit for 30 minutes to an hour, keeping the cloth damp by spraying more vinegar if needed.
3. Remove the cloth and scrub gently with a soft sponge.
4. Rinse and dry as described above.

What Not to Do

• Avoid abrasive cleaners like scouring powders or steel wool, which can scratch glass tile.
• Don't mix vinegar with bleach or other cleaning products, as this can create harmful fumes.
• Don't let vinegar sit too long on acid-sensitive glass, as it may etch the surface.
• Avoid using a razor blade or metal scraper, which can easily damage the glass.
