When hard water gets on glass it starts to calcify. If you clean it right away it is easily removed but if left on the glass it will increasingly become harder to get off. Just like with everything else there are many products out there for water spot removal but not all of them work good.

Supertints set out to find out what is the best way to get rid of those unsightly water spots. What we learned was that there are many products out there that are abrasive and actually put fine scratches in the glass. They don’t work very well either. You never want to use Steel Wool. We found that the best way to remove the water spots is with an acid treatment. The acid will break down the calcium and bring back the shine to your glass. Once your windows look good again you can prevent it from happening again by not waiting more than 30 days to clean your windows. Supertints offers spot removal for cars, homes, businesses or anywhere you might need it.
