How does one get very hard water spots off auto windows and mirrors? Thanks
 
Ceri Glass and a rayon pad using a rotary. Side mirror is a film and cannot be polished like glass.
 
Have you looked at the Autogeek Web site? Autogeek sells awesome products to remove water spots. There are some brands you find at auto parts stores. Check Autopia.com as well. Autogeek and Autopia are sister companies in Stuart Florida. Depending on the product you choose, you may need a dual action buffer. Mike Phillips of Autogeek is a powerful source of information. He has been in the detailing world for 20 plus years

Duragloss Nu-glass is a nice product. Works just fine for mineral deposits. AG also sells some house-branded glass "polishes"- McKee's, Wolfgang, etc. I've only used the Duragloss.
 
You could try using Mckee 37 Glass Restoring polish, it works pretty good on windows. You can just use a regular finishing pad of some kind and run it over with a buffer.
 
For hard water etching or stains on my truck windows, I used my GG 3 in DA. The pad I used is from the 3M headlight restoration kit. The compounds I have used are Meguiars M105 and CG. I had positive results with both. The Meguiars M105 dusts a lot. CG needs to be kept wet but the fling I had caused a mess.

I used Duragloss Nu Glass 755 with a white pad and a DA at a speed of 4, and it worked excellent on a windshield with SEVERE water spots that were etched. It took 2 or 3 applications for it to work, but it did and now my windows are crystal clear.

I researched this topic for hours. You will find practically no bad reviews on the Duragloss stuff, and it is very inexpensive.
 
I'll also recommend DuraGloss Nu Glass. Works great for hard water spots on glass. In the past i have used warmed white distilled vinegar if you're in an immediate pinch for getting them off quickly. I spray it on the glass somewhat liberally then soak a large WW MF towel with that same solution, let it lay on the glass and let it dwell for a bit...maybe 5-10 minutes. Let it work on the spots to reduce their hold on the glass. Then wipe off. I don't like it to drip on my paint only because i am not sure if it will remove any LSP's so you might want to be careful to keep it off the paint.

Interesting.. So that explains why they're usually scratched up.

Interestingly, i just washed the side mirrors on a Toyota Tacoma and a Honda Pilot-- I used the exact same type/brand of towel on both. The Toyota mirror ended up fine but the towel made an absolute mess out of the Honda. Good lesson to learn just how different surfaces can respond.

I don't even bother washing them on any vehicle during the bucket wash these days.. I just leave them until afterwards when I'm cleaning the glass.
 
Try vinegar solution to clean hard water spots in your car windows and mirrors. I've used vinegar and it helped me a lot to remove the hard water spots off the windows. Here are few tips which I found online that could help you out. Else you can use stoner's invisible glass to remove the hard water spots. Don't use any abrasive scrubbers because they may become etched into the glass and paint. Also park your car away from sprinklers on hot and sunny days.
