[QUOTE=longhorn294]  How about water spots just on glass? I've tried everything I know and can't get them off.[/QUOTE]

I like vinegar & water mixture along with newspaper to clean glass with.

Then I wax the outside glass along with the car. (No need for RAINX.

I personally love claybar. It works great on everything. I brought back the shine on my 97 blk farm truck. Its had never been waxed and wasn't washed the first 7 years I owned it.

 Thanks Scott and Jamie. I guess that's one thing I haven't tried. I think I remember someone talking about this problem in the past about maybe the glass being etched from acid rain or chemicals in the water? If that's the case, can it possibly be polished/buffed off?

Water spots on glass when I detailed cars in the 80's we used the super fine steel wool with distilled water or windex, sprayed on and rubbed lightly and it cut through the water spots (hard water deposits) and then cleaned the glass as usual. Of course the steel wool will be one use only.
