Hard Water Stains
On my new Coach as well as the one prior the side windows were badly stained by hard water. On the first coach the staining was so bad it really impaired your view.
I tried everything that I could think of and also that had been recommended including vinegar, CLR, ceran cook top cleaner, buffing compound, chemicals and even scotch bright pads. Nothing seemed to do the job without marking the glass. I knew that acids would remove the spots but was concerned about the surrounding areas. I came across a product by C.R. Laurence called Bio- Clean (WSR1) this product worked great on the heavy stains on my old Coach, however I must warn that it is very aggressive and can leave light scratch marks on the glass. On my new Coach I used C.R. Laurence Sparkle (SP101) it was less aggressive and took more elbow grease to apply but worked well on less stained glass, having said that it only took about an hour a window. I would highly recommend these products for removing hard water stains. -

Lee,
I use Wipe Out’s oxidation remover and it works well. We’ve had Ted at several rally’s in the past and the product works, although pricy. Here’s the website: Wipe Out

Why not use what dissolved the hard minerals in the first place? Water without minerals – distilled water! Soak a white paper towel (or a bunch of them) and keep the area very wet with the distilled water. It will take some time to work, but it won’t damage anything in the process.

I am a mirror manufacturer and stains that are etched into the glass are very difficult to eliminate,I have found that cerium oxide which is a polishing compound with lots of elbow grease works very well.Sparkle from C R Laurence is a good product and will do the job.

White vinegar will take them off glass quickly and easily. Keeping in mind that vinegar is an acid and should be rinsed off very well.
White vinegar is used to remove hard water residue from coffee pots, shower heads and the like! It works as well if not better than the products like CLR, but if you’re worried about your paint the safest is distilled water.
Never use acid based products on stone or concrete.

I have had substantial spotting on the glass on all my coaches.
Fortunately I decided when I first experienced it in the early 90’s I decided what ever caused it would continue to cause it so trying to make it go away, only to have it return would be a waste of time and energy.
Bot over the years I have often wondered if it was spotting from mineral deposits, or is the glass etched from acid rain. I’m just curious because I have no intent of doing anything about it.

I have used the Bio Clean with an orbital buffer and it worked very well.
Not a whole lot of elbow grease.

I’m in the yachting industry, water on glass happens, salt water on glass in a pain.
Flitz and a little elbow grease seem to work every time for me, it also leaves a nice coat of wax on the glass.
