First, it helps to understand why water spots appear: minerals and other impurities in your water.
Hard water means more minerals — and a tougher time with water spots. But even when you don’t have hard water, there are still some minerals. Over time, anybody’s glass shower doors can end up with water spots.
What gets rid of water spots? Acid.
Many common cleaners, including bleach, are actually basic, or alkaline — the opposite of acidic. If you’ve sprayed Clorox on your glass shower doors and had a tough time with the stains, that’s because you’re using the wrong kind of cleaner.
Good Cleaners for Glass Shower Doors
- Commercial products include Lime-A-Way, CLR, Bar Keepers Friend, and other acidic cleaners. Don’t bother with most multi-purpose cleaners or tub & toilet cleaners.
- Homemade, DIY solutions can start with vinegar — standard white vinegar in the jug will do. Try cleaning with pure vinegar, or make a paste with baking soda for even better results. For small spot cleaning, you can simply rub a lemon wedge directly against your glass shower doors.
- Scrub with non-scratch sponges, or you can simply use washcloths or paper towels. Avoid steel wool and tough sponges not labeled non-scratch. Once scratched, your glass shower doors will pick up minerals and grime more easily.
Essentially, you just need to apply an acidic liquid and gently scrub away the water spots. With the right cleaner, you won’t need superhuman strength to scrub the stains away.
For prevention, many people get great results from applying Rain-X Rain Repellent. However, products like that should not be used on etched or frosted glass shower doors.
