I have some really bad water spots on my rear and side windows of my Tundra that I am going to work at to get off. I have already tried straight vinegar and Bar Keepers Friend with no luck with either one. I read that I can use 0000 steel wool, so I got some last night from Ace Hardware and tested out a spot and it does work. It's not easy, but it does work.
So my concern/question is: can I rub too hard where it might scratch the glass and is there any lubricant that I need to use(water/detail spray) while doing this?
