Film on Window

[mingle51]

My 1979 airstream has wing Windows which I've managed too take apart and clean the sealant and gunk from the glass. But a film still remains on the glass. I've used denatured alcohol, baby shampoo and 00000 steal wool. Glass polish and scraped in with a razor blade. I've been unsuccessful in removing the film from the glass. Any suggestions please?

Try a clay bar.

The glass may have become etched, and only can be made clear again with a glass polishing process. Sorry, I can't tell you more about that, I have never done it. However, sometimes certain water from sprinklers will etch glass and it is virtually impossible to make clear again. This is not a deposit on the glass, but a removal of the glass surface itself.

clay bar? Not sure what that might be Paul

[Paul Dobbin]

The clay bar is a tool to clean the surface of paint to get it smooth enough for polish. They also make it for glass. I guess you could use a clay bar with
soap on glass to clean it off and make the glass surface flat.
It works by lubricating the surface and rubbing the clay across it with a cleaner to get the surface FLAT. It's the ultimate cleaner for dirty rough paint and works well on glass too. Available at auto parts stores.

This is what I used to clean the hard water stains of my wing windows and it works great just lost of labor.. Gordon Glass Cerium Oxide - 8 Oz with 3" Felt Polishing Wheel..

I used it with my cyclo polisher on all my windows, including my vista views (which were taken apart), and they all cleaned up really well. Takes a little time, however.
