How to Remove Hard Water Stains From Glass Shower Doors
That cloudy white film on shower glass is mostly minerals from hard water, plus soap scum. Minerals dissolve in acid, and white vinegar is a cheap, safe acid.
Quick answer
- Fill a spray bottle with equal parts warm white vinegar and dish soap.
- Spray the glass, wait 30 to 60 minutes, and keep it wet.
- Scrub with a non-scratch sponge, rinse, and dry with a squeegee.
- Use a baking soda paste on stubborn spots.

Step by step
- Warm the vinegar in the microwave until warm, not boiling. Pour it into a spray bottle with an equal amount of dish soap and shake gently.
- Spray the glass generously.
- Wait 30 to 60 minutes. For heavy buildup, press paper towels soaked in vinegar onto the glass to keep it wet.
- Scrub with a non-scratch sponge.
- Stubborn spots: dip the damp sponge in baking soda and scrub gently.
- Rinse with water and squeegee dry.
Very heavy buildup
Try a commercial lime and calcium remover, following the label and ventilating the room. A melamine sponge (like Magic Eraser) can help, but use it lightly because it can dull some coatings.
Never mix vinegar or other acids with bleach. It creates toxic chlorine gas.
Don’t forget the tracks and frame
Pour vinegar into the door track, wait 30 minutes, then scrub with an old toothbrush and wipe dry.
Keep it clear (the 10-second habit)
- Squeegee after every shower. This one habit prevents most buildup.
- Spray a daily shower cleaner, or a 1:1 vinegar and water mix, once a week.
- Consider a water-repellent glass treatment.
- A water softener reduces mineral spots throughout the house.
FAQ
Is vinegar safe on natural stone around the shower? No. Acid can etch marble, travertine, and limestone. Protect stone and wipe up any drips right away.
Always test a cleaner on a hidden spot first and follow the care label. Never mix bleach with ammonia, vinegar, or other cleaners. Ventilate the room and wear gloves when using strong products.
