I have nearly driven myself crazy trying to get the spots off my windshield. I have tried all methods and cleaners, and I can't get them off. I think what caused them is the one and only time I took the truck through a hand wash booth. At the end, the machines sprayed on a "wax". What can I do to get these off?
Thanks

 

So... you think the spots are from the 'spray on' wax from a tunnel? Pretty unlikely honestly... (unless they were having chemical issues).

Odds are, you're dealing with a hard water deposit of some sort...

Rather than us toss ideas at you, why don't you tell us what you've tried. Just one note... have you tried vinegar?

 

Whenever I get spots ( from rain or after a wash & it dries up too quick which I try avoiding ) I take my Zaino Z12 glass cleaner & polisher..

I had terrific results from a product I picked at my local glass place.

I had a shell on my truck for about two years. I was lax on keeping the rear cab glass, and the forward shell window tended to properly. The water in our is pretty hard, so you can imagine what this glass looked like.

Using a white scrub pad, and the Amaz worked wonders.

If you have a local glass shop, stop in and see if this stuff works for you. They might even have free samples, my place did.
