AMAZ - Water Stain Remover

Wow - this stuff REALLY works!

About 8 years ago a glass guy recommended it to remove extreme water spotting on a patio door. It worked, but because the glass was so bad there was a lot of rubbing.
Light spots like in the photos will melt away, follow up with a GOOD glass cleaner, i.e. Sprayway Glass Cleaner. Windex is bottom shelve.

This is my go-to product for glass water spotting!

I am now looking / wondering, when the glass is all clean and shiny if a glass sealer would be in order. Or maybe just use rain-x?

Enjoy!
