How to Remove Hard Water Stains From Glass (And When to Call the Pros)

Hard water stains are more than just a cosmetic issue—they can actually damage your glass if left untreated. If you’ve noticed cloudy spots on your windows that don’t wipe away with standard cleaners, you’re probably dealing with mineral buildup. It’s common in Bend thanks to our high-mineral water and irrigation systems.

Here’s how to remove light stains yourself—and how to know when it’s time to bring in a hard water stain removal expert.

1. 🧪 What Are Hard Water Stains, Anyway?

These stains come from mineral deposits—mainly calcium and magnesium—that are left behind when hard water dries on glass. They look cloudy, hazy, or white, and they stick around even after cleaning.

If left too long, these minerals can actually etch into the glass, making stains permanent.

2. 🧼 Try These DIY Solutions First

You can try some home remedies for light stains:

  • White vinegar + water (50/50) – Spray and let it sit, then wipe.

  • Lemon juice – Natural acid can help break down buildup.

  • Baking soda paste – Gently scrub for more stubborn spots.

Always test a small area first and avoid anything abrasive—scratching your glass will only make things worse.

3. 🛑 When to Call a Glass Cleaning Pro

If the stain has been there for a while, or your glass feels rough to the touch, it’s time for professional glass cleaning.

A trained window cleaning company has special tools and solutions (like acid-based treatments and polishing systems) to safely remove mineral buildup without damaging the surface.

4. 🧽 Prevention = Less Stress

To avoid future stains:

  • Angle sprinklers away from windows

  • Rinse windows with soft water if possible

  • Schedule routine window cleaning services to catch buildup early
