How to Prevent Water Spots on Glass

SUNNYVALE — A common problem with glass shower doors is the formation of water spots. Not only do these spots obscure the clarity of glass, they can also become permanently etched into it over time. The good news is, if your shower door is less than two years old, it’s unlikely that your water spots are permanent, so there’s still time to take proactive measures.

Preventing permanent water spots entails just one simple step: applying Rain-X to your shower doors. Typically used on car windshields during the rainy season, Rain-X is a water repellent, which means it causes water to run off glass surfaces rather than stick to them. With the regular application of Rain-X to your shower doors, you can stop water spots before they start.

You can find Rain-X at any auto supply store. Keep in mind that after cleaning your shower doors with a glass cleaning product like Windex, you’ll need to reapply the Rain-X coating.
