I parked next to where sprinklers were watering the grass and got water spots on the right side of my 2005 Elantra. I got the spots off the paint with a clay bar but can't find anything to get them off the glass. The water is well water and someone told me the spots come from the sulpher in the water. Any suggestions?

 

Clean the windows with Bonami cleanser. Don't use any other brand. Besides the water spots, you'll be surprized how much crud you cleaned off the glass. If you get cleanser on the paint, flood it off with a hose.

 

Yep, I've use Bon Ami many times:


Invisible glass works great too:

I tried Bonami and it did not remove the spots. I emailed customer service at Zaino and asked if they thought the Zaino Z-12 Clear-view Glass Polish would be effective on these spots. Sal Zaino replied "yes, Z-12 should remove water spots on glass". Has anyone had any experience with Z-12?
