Glass Cleaner Recs?

[OldBlevins]

My windshield is spotted with what looks like mineral deposits. My standard industrial-strength glass cleaner doesn't do a thing for it. Do I need a glass-stripper or something else? Thanks.

You may be able to clay bar it and get the spots off. Are you sure you're not seeing pitting from sand and debris hitting your windshield? Mine had awful pitting in it before I swapped it out earlier this year.

Another thing you can try, tested first in an inconspicous corner (lower passenger side by base of windshield would be a good spot), would be "barkeeper's best friend," found in the grocery store isle in a "comet" style container.

This stuff is amazing. It polishes glass like no other product. Works great on wine glasses and the windows in your house too.

However, I must say that I've never tried it on a windshield and therefore you should be extremely cautious to test it before you haul off and do a big spot and find out it caused more damage than good.

Clay bar is a good idea. I used Klasse all-in-one on my windshield last weekend and it took off some deposits that Stoner Invisible Glass missed. If you already have Klasse it's worth a try but otherwise the clay bar is much less expensive.

Thanks, guys. I'll try the clay bar first as a safe method and if it's still a problem, try the barkeeper's best friend on a small spot on my wife's side of the windshield.

Most often (if they're deposits and not etchings) vinegar will break them down, no problem.
