help w/ spotting on all windows

[ssummit camaro]

when i picked up my car from dealer i told them not to wash it. i then took straight to get windows tinted. a few days later i saw all these water spots and it thought it was inside the glass but it was outside. i used vinegar on all the windows and the spots were gone.

There is actually a tsb on that, I will look it up later when I have more time and post it, there is a certain chemical to use to remove them and I can't remember what it was but I will let you know soon

Zaino Z-12 works fantastic for cleaning the glass for water spotting and gives it a tad of protection as well. I love it.

This bulletin is being revised to update the models and model years. Please discard Corporate Bulletin Number 09-08-48-002 (Section 08 - Body and Accessories). Condition
Some owners may comment that marks/stains appear on the windshield when the windshield is wet.
Cause
This condition may be caused by contact between the windshield and the vacuum hoses or other tools used in the assembly process. This contact may leave a residue that creates a water repellent surface on the glass which, in wet conditions, appear as marks/stains on the surface.
Correction
Important DO NOT REPLACE THE WINDSHIELD FOR THIS CONDITION. To clean the windshield, use Eastwood Glass Polishing Compound*. Follow the manufacturer's directions for product use. Use only hand tools. DO NOT USE POWER TOOLS.

Bulletin No.: 09-08-48-006
Date: September 18, 2009
Subject: Clear Stain or Film on Inside Perimeter of Windshield Glass (Clean/Polish Glass)
Models:
2010 and Prior Passenger Cars and Trucks (Including Saturn and Saab)
2010 and Prior HUMMER H2, H3 Condition
Some customers may comment on a clear stain or film on the inside of the windshield glass. This condition appears along the outer edges of the glass along the top, bottom or A-pillar areas. Normal glass cleaning procedures will not remove the stain.
Cause
The assembly plant uses a clear sealer/primer on the outer edge of the windshield glass to improve adhesion to the urethane adhesive that bonds the windshield glass to the vehicle body. Excess sealer/primer may drip or flow onto the windshield and cause a stain. Once the sealer/primer dries, it may appear to have etched the glass.
Correction
Note
A "white" type of toothpaste is recommended for this repair. Gel-type toothpaste may provide less satisfactory results. Use a small amount of toothpaste on a soft, cotton cloth to polish the stained area. It may be necessary to wrap the cloth around a paint stir stick or a similar tool to reach the lower corners of the windshield glass.
After polishing the glass, clean the inside of the windshield glass with a clean, damp, cotton cloth and verify all of the stain is removed. Do not use any cleaners or solvents - use only clean warm water.

I'm with el es ex. A little bit of the glass polish and your glass looks great.

[trixienurse]

vinegar/water mix and rub glass with steel wool grade #0000 works good

[2011ss/rs]

I picked up a bottle of Nu Glass at a car show and it worked great looks like new glass. You put it on the glass with a terrycloth towel rub it on like wax, let it haze and begin to remove with a terrycloth and presto all of my water spots are GONE!!!! and I had many spots which made night driving a pain in the glass the bottle cost was $8.00. If you need information PM me.
