Hard water spots on windows

Ok well after work I stopped by a glass shop that just so happens to be about a quarter mile down the road from where I live. They said they don't actually remove the spots themselves but the guy said he had something that should work. After looking at my windows he told me that my spots were really bad. Luckily the stuff he ended up selling me works great. I knocked out only 1 window so far but it looks amazing now. This stuff does leave very tiny and almost unnoticeable swirls but he said some car wax will hide that and protect them. Once I get up tomorrow, provided this storm is gone, I'll go out to finish the job and let you guys know what the stuff is.

 

Use some real polish and a real buffer, not some autozone junk.

I've used an orbital Porter Cable 7424 buffer to actually polish out deep scratches in glass, much deeper than any water spot etching.

A rotary buffer with a wool pad will really do the trick.

 

The solution is called Bio-Clean. Came in a white bottle, the stuff is a green liquid (a little thick) and smells like toothpaste. I considered polishing the windows after mainly cause I bought a craftsmen random orbital buffer about a year ago and still haven't used it. But I'm leaving for Germany soon so the truck can only get so much of my time and waxing is a high priority to keep it protected while I'm gone.

 

It will be for about 2 months. One of the guys going with me said I can leave the truck at his place and his wife will run it from time to time to prevent problems. I always make sure someone takes care of my vehicles when I'm gone more than a month.
