Window water spots

Over years of washing, my Cutlass has plenty of water spots on the exterior glass. Is there any product or something to remove these spots?

I would use Invisible Glass cleaner with newspaper (not pages with any color) to clean them. Then you might try RainX on them. Good luck.

you can buff glass like paint but you must be very careful not to get the glass hot it can shatter. There is a glass repair kit from eastwood i think and it has the d.a. sander 1000 2000 ad 3000 grit it removes light scratches. I have buffed glass but never sanded it . just thought id mention the kit i saw a while back good luck .

have you tried a razor and glass cleaner?

I've use regular automotive paste wax to remove some stains also.

If it's just hard water spots use One Grand glass cleaner/polish.
I've been using it for years and it's does the job better than any other technique or product that I've ever used.

The Eastwood kit contains cerium oxide powder and a felt buffing pad that you mount in a drill. It's more to buff out fine scratches and would be overkill for water spots but would work, you have to be careful using it or you can crack or distort the glass.

If it is just calcium deposits, vinegar will dissolve it. Like other glass cleaners, I would avoid getting it on paint, though.

.0000 steel wool with a good glass cleaner works really well on 'hard' water spots.

Start easy and work up from there. If really just hard water deposits, a mild acid (vinegear) will do the job as Rob suggests. From there, try a razor blade or 0000 steel wool like both Mikes said. I would go to abrasive buffing only if the other options do not work and might consider letting a pro do it

Coca-Cola will work also (contains phosphoric acid I believe) with newspaper. Make sure you rinse it thoroughly from the paint afterward.

Only thing that has ever worked for me is CERAMA BRYTE ceramic cooktop cleaner. Available at Lowes/Home Depot. Contrains citric acid I believe. Apply to cool glass with a wax applicator and do small sections at a time. It does require a healthy does of elbow grease but works great.

Thanks Scott 442, I'm going to try this stuff! I have spots on my Buick glass. I've tried most of the other stuff luck! I have the Eastwood kit, I used it on my Olds. It was super messy to use and only a bit effective on the light scratches I was trying to get out. Spent hours and hours, ended up buying all new date coded glass. Might have to get glass for the GS too, I'll try this stuff.

Water that leaves spots has calcium in it. Try using 1 tablespoon of tri-sodium phosphate
in a quart of water. The product is very cheap and you can use it on a million other projects around the house...removes mold, mildew, great deck cleaner garage floor cleaner. I manage a 40 story building and had the windows cleaned.( had not been done in years) and the contractor use TSP.
