I have mineral spots on my windows. So much so that with sun glare it is difficult to see. I have tried everything from vinegar to barkeepers friend. I even tried toothpaste. Nothing even touches them. Any brats have some advice? Hate to have to reglaze but it sure would be nice to see out the windows.
Thanks
Chris
 
I'd contact Diamond Sea Glaze. If anybody would know it'd be them. They are just outside of Vancouver and have been extremely helpful.
 
Amaz clean and green Water Stain remover:

This was recommended by one of our local glass companies, for both cars, and shower glass. If you want you can add using a "clay bar" as used for auto detail.

We like to keep Rain X on our boat windows. It often helps to repel salt water better than trying to keep the windshield clear with the wipers. (We do not have a "washer" system installed, but that can help---if you use demineralized water.
 
thanks Bob

Curious if other products besides Rain X are available and better
 
Lake Powell, Lake Mead, and the Erie Canal left hard to remove deposits on our boat. CLR removed them, but note the aluminum caveat. I wiped down with 100% CLR and immediately pressure washed. No problems, worked well for me. Cary Co. website says ok to use with fiberglass. www.thecarycompany.com/containers/facility/clrfaq.html A chemist friend of mine said that Phosphoric acid could be a problem with fiberglass if there was a prolonged exposure, but the current composition is non phosphoric acid. Apparently it may cause the inherent flexibility of fiberglass to be reduced. Read the label. Caveat Emptor.

I bought some stuff years ago from a glass shop. They use it on mirrors and glass to make them clean and sparkle. Used it on a pitted car windshield and glazed over headlights. Works good. It's a powder that you dip a damp rag in then use a circular motion on the glass. I'll be happy to send you some, though I don't know what the postal service would say if they saw it was a light colored powder substance in a baggy!
 
The best glass cleaner we have found is called Sparkle. Worked like a charm when we had stains on our windows.
 
I have tried everything. I contacted Diamond SeaGlaze and they recommended isopropyl alcohol, scrape with razor blade, followed by windex. Had no effect whatever. At this point I think I will just forget the windex and drink the alcohol.
 
Can you tell if they are a surface deposit, i.e. raised or are etched into the surface?

I've also used Star Brite's RainView. Can't say if it works better, but it does work well. I apply in the spring, and it helps very considerably through a summer's cruise.

Cleaning thoroughly first, and applying carefully per directions, with lots of elbow grease, are essential. A little while after application, if you look outward through the window and it's hazy, you haven't rubbed enough.
 
Really. Give Sparkle a try, get it from any glass company. We had severe rust stains on the center front window that had been coming down (we think) from the horn. Sparkle took it right off, no razor blade or anything like that.

It's wierd but it almost seems as if it is in the dlass itself. If I scrape hard with a razor blade from each side, it has no effect on the deposit.
 
Thanks Pat. I will track down somw Sparkle and give it a try.
 
C-jeep, it is etched. You can polish it out, but there will still be irregularities in the glass. Surface grinding could remove it, but impossible while installed. Replacement of the panels would be the only 100% fix, if you can not live with what polishing does. Note that polishing compounds come in finer and finer grits, down to a grit which will eliminate any haze or obvious lines, but the surface will still be a bit irregular.

Protecting the glass in use with Rain-X or similar, with a soapy washdown regularly probably the best preventative.

thanks Dave. I have come to the same conclusion. I thought I might try to grind it out of the aft side window since it needs replacement anyway. If it works will try the windshield glass.
