Success with double pane window clean-up
I finally decided to see if the double pane windows, in this case a vista view oblong with tempered glass outside and plexiglas inside, could be cleaned up to remove the decomposed mylar sunguard. I am happy to report that good results can be achieved. It was easier than I thought it would be. Basically, after the window frame has been removed from the trailer by drilling out the rivets, the two frame halves are separated by sliding them in opposite directions. Once this is done, the panes are removed and cleaned. The mylar comes off with a razorblade. The frames are aligned at the seam by four roll pins 1/8 X 3 3/4" which will have probably corroded in tight. Put a little liquid wrench or the like around the seam and let it soak in. To separate the window I put one side in a vise and used a hardwood block and a hammer to drive the opposite member off. After everything is cleaned, rub a little silicone grease onto the gaskets to help them slide in. You should replace the roll pins if they are damaged. The unit was reassembled with hand pressure and taken up tight with a mallet. It's a fair amount of work and requires olymic rivets to reinstall the window, but the window is now a good deal clearer than this description. If I were going to do several I would probably make a jig to separate the frames.
