All cars that have been manufacturered in the past 20 years have safety glass that actually has a coat of plastic on the outside and inside of the glass. Chances are, the acidic wheel cleaner probably ate into the plastic layer. But before you trash it, clean it with some automotive specialty glass cleaner like EagleOne 20/20. Dry it with newspaper which will actually shine the glass. Then either use something like RainX or RainX windshield wax to fill in the pits on your glass. Apply two coats and buff it out THOROUGHLY with a clean terry towel. Buff it out like you would buff out automotive wax on paint and then rinse the windsheild to get rid of the streakiness it may leave behind.

If all else fails, crack your windsheild and claim it on insurance (just a joke, don't report me for insurance fraud please )
