I have tried to remove what seems to be RainX from the windshield with the RainX removing product without success. I am trying to do that because there are hard water spots that I just cannot remove no matter what I do, so I assume that there is RainX or some other "polish" covering them. Any suggestions??

Hard water spots on glass are removed with vinegar. Try 50/50 water/vinegar mix to start with and increase strength if needed.

Thanks, I have tried that. I researched and tried everything I could find. I thought maybe I could find someone who has experienced this first hand.

I used white (mild) rubbing compound on my windshield with a buffing pad to get rid of my hard water spots.You might try using a foam pad on a drill. Tape off the molding with blue painters tape.

Is there a foam pad bit for the drill, or did you rig something yourself?

Darn it, ran out of it. But I will certainly try. Luckily my water spots are no where near as bad as those on the video

Go buy Bon Ami at your local food store. It's ment to polish glass.

Have been using Bon Ami for lots of things for years, it's a polish, not a cleanser.
In the owner manual for the 72 Chevelle I used to own GM said use Bon Ami to clean glass.

Used RainX years ago when it first came out, loved it in the pouring rain but found once applied it was all but impossible to remove it permanently from the windshield. You could always see where the wipers tracked when you washed the car. When a new windshield went in that car I never used it again.

When I worked in a detail shop we used to use windex and steel wool to get water spots off of windshields

Years ago at the local auto glass shop, which is now out of business, the son gave me a tub of Cerium Oxide in paste form to remove a scratch in a side window of my daily driver. Using a felt wheel and making sure you don't heat the glass it did a very good job. Would think it would be killer for water marks.

if no good result yet, try mister clean with ammonia, that should cut though any crud.
If not good progress with the previous treatments, try CLR (calcium/lime/rust) remover, available at most supermarkets, Home-Depots, it should cut through any stain without leaving a trace.

I wonder what grade of steel wool to use? I am sure it has to be the finest?

Are Bon Ami and Bar Keepers Friend kind of the same thing?
