Well my whole truck is detailed and it looks beautiful, but there is a few spots on my rear window that have some tough water spots. I tried straight white vinegar and they wouldn't remove...what is the best way to get rid of these?
 
I thought about using my Pinnacle Cleansing Lotion on it, but I am not sure that is a good way to go haha
 
Try using carpro spotless, hopefully this will do the trick. If you want to step it up, you will need a glass polish, a glass polishing pad and a polisher. Hope this helps.
 
have you tried clay and/or a foam applicator with polish or compound?

CarPro spotless will work.

I have also been successful polishing glass when I was polishing a car. I kept on going to the windows which were heavily water stained with a compound and cutting pad and it worked to get the windows nice and shiny and water spot free.

You've gotta use real acid.

You might need to expound on that one. (Different acid's being used in cleaning for different situations.)

I know I used to buy hydrofluoric acid in 5 gallon tubs for use on my tow trucks (for 18 years in fact) and while that stuff will clean a rollback bed, be that steel or aluminum (all mine were aluminum) and it'll make a chassis look like new, IT WILL ETCH THE LIVING SNOT OUT OF GLASS!!!!!!

Just having the mist in the air will etch glass, (and it's not good for paint either... but this thread is about glass). ;) For that matter, it'll ruin all your polished stainless as well. :eek:

OTOH, it's the primary acid in (acid type) wheel cleaner. ;)
 
The toughest water spotting i ever experienced on glass i tried a method i heard somewhere online. Can't remember if it was here or elsewhere. This customer admitted to me that her car is left exposed to her lawn irrigation sprinklers on the passenger side every single night. I remember how severe the spotting was on that side!

I cleaned the windows with window cleaner first to leave only the very hard water spots. I then warmed up some white distilled vinegar and sprayed it to almost saturate a few WW MF towels and layed them on the glass while i cleaned the wheels, wells and tires. Their dwell time was probably 20-30 mins. on the glass. I then took some 0000 steel wool and more window cleaner and lightly worked them some more which dramatically reduced them. I then took a white LC pad, my PC and sprayed more vinegar on the pad and buffed the remaining light spotting off the glass. I then washed the vehicle normally.

Now i know this seems old school and was a few years ago before all the new age spot removers appeared for us on the market. Plus it sounds like more of an effort compared to what is available now but it worked extremely well. Just a suggestion from my experience.
 
I think I will try a cutting pad and some invisible glass water spot remover
 
I got great results from Duragloss 755 (Nu-Glass). Went at my old jeep's badly spotted windows with a 3" cutting pad on my rotary. Had already tried the vinegar, spot removers, regular polishes, and Diamondite—all to no avail. Duragloss was the real deal. (Surprisingly, I've never used any of their other products.)

Also mothers water spot remover. I always had great success especially with shower mirror which was not cleaned for few years. I still don't understand why this product under evaluated and not reviewed at all.
 
Yes using real acid will work, look for the automotive grade acid. Just use extreme caution using it, since it may stain rubber and paint as well. and ofcourse burn your skin.
That is why i prefer carpro's spotless, safe but effective.

How about ceriglass??
 
Yes, ceriglass is effective but like an abrasive polish or compound on paint i believe it cuts glass. I like to treat glass like paint and seperate my approaches to removing above surface defects (water spots) from removing below surfaces defects (wiper scratches etc.). I treat the latter with a cutting approach and the former with a chemical approach. I like something to break the super glue like bond of water spotting without cutting into the glass material.
