I bought a pair of new old stock windshields for my 1957 flxible starliner (rare as hens teeth) which were foamed into the shipping box 20+ years ago and never opened until I installed them recently. when I went to clean them I discovered a film sort of a light frosting that I believe was caused by an acid from the chemical action of the curing foam they were were packed in years ago. Does anyone know how I could polish the glass to remove this frosting ? I desperately need to save these windshields. |

There are glass polishing systems out there,
http://www.gtglass.com/index.htm
Probably pretty pricey, but you may be able to find a company that can restore them for you using this type of equipment.
I would first try every solvent I could find to be sure they are actully etched and not just dirty. |

Are you certain that the frosting is on the outside and not between the layers and in the "plastic" that is sandwiched between the glass layers? I had this on a windshield for one of my classic cars and ther is nothing that could be done to clear it up. Hopefully your frosting is actually on the outside and can be polished. |

Look at WWW.Eastwood.com.
Diamondite Glass Cleaning System, cat. no. 40057Z, $29.99.
Eastwood's stuff is a little pricey, but all good quality.

Is there a "cure" for plexiglass that had the protective paper in place too long?
All the paper is long gone but the old glue remains and the visibality thru the window is poor.

Fred,
Try a product called 'Goo-Gone", available at WallyWorld or the box stores.
Use it in a small inconspicous place first to check for compatibility.
I used it on some Plexi that had sat in the sun for a couple of months.
It took the old paper and glue off with no problem.
Of course, it may not work on every type the same, but it's a place to start.
Another product called "Krud Kutter" Tough Task Remover may be an option also. I haven't used it yet, but my wife bought 2 bottles of it and it looks promising.

WD-40 or common Mayonaise works wonders for getting glue off..
(That "Purple Power" stuff isn't too bad, either!) |

I've used laquer thinner to clean up old plexi, worked well without hurting the plastic.

Can you scratch off any of the "frosting" with a razor-knife? |
