Hey there DC! I have a problem.. a friend of mine wants me to help her detail her car. Problem is that her windows are full of hard water spots. Does anyone have a good off the shelf product that would take these spots off, and what is the best process to take the spots off? HELP!
 
Bon Ami or Bar Keeper's Friend have worked well on tough spots for me (they are not supposed to scratch, and I have never had any problems using the stuff, although it does conflict with my usual beliefs of not using household cleaners on my vehicles anymore), as have chemical cleaner polishes. You might also want to try vinegar and water (1:1) and sometimes even claying will help.
 
For OTC, Glass Science's Glass Scrub worked on water spots that were a bit more than outlines (not clouded through out). It may work on more extreme spots, but I haven't had any occasion to try it on such.
I don't know if it's very readily available anymore, but Strip It (Pylon) Windshield Cleaning Compound worked very well on hard (lots of rust) water coated glass. I used it on glass that hadn't been cleaned (other than when it rained) for over 10 years. Rusty haze that looked like it was nicotine coated, but it was on the outside! Worked quickly and easily. Not much scrubbing. It came in a black "toothpaste" tube.
Also, chrome polish is supposed to be good on glass, but I haven't tried it on water spots.
 
the best i have used is the vinigar and water. always works. plus you probally already have it without buying anything.
 
Thanks! Well, I guess thats it then.. I'll be trying the vinegar and water first (since there is zero cost there). So, do you have to scrub it in, or just wiping with a cloth will do? (Sorry for the lame questions...)
 
Soak you a towel or rag in the solution, apply it liberally to the windows, let it sit/soak, and wipe it off. Some areas may be helped if you scrub a little with the towel.
 
What about Diamondite D3 compound glaze - I have had to use menzerna intensive polish to remove them previously.
Next time I find a car with em, I'll give the polishing soap a try just out of curiosity
 
The water and vinegar will remove quite allot depending on how bad they are but I have yet to see any that it has not removed.....You can follow that up with some polish to remove the rest..........That should do it.....I have found that janitorial supply places have all kinds of cleaners for these types of problems....I'm sure you have one in your area, you might check just make sure that its tint safe.
