Default How to remove CA stains on clear plastics.

I am desperately searching for a way to remove the clouding stains that seem to come from the "smoke" from curing CA glue, and then suddenly appear on plastics...particularly canopys, ruining their appearance. Is there anything that works to make the plastic nice and clear again???
Thanks for the help.

Polish it off with car wax. Stains on chemical resistant surfaces e.g. monokote can be removed with acetone

I will try the car wax...but the acetone...uh uh...I'll try that on a piece of scrap first. My experience with acetone is that it is too strong and it permanently blurs the surface, and in some cases it trys to disolve the plastic that the canopy is made of. Also, I have seen acetone remove the color pigment from plastic film coverings like monocote.
Thanks for the leads, at least it gives me something to try.

Jim, that's what I said. Don't use acetone on surfaces which are not chemical resistant. If you use acetone on your canopy, it will probably get worse. I have not experienced problems when swabbing a small amount of acetone on monokote to remove ca fogging near ca hinges. All the best !

GP debonder on a paper towel worked great on my DPM canopy; odorless ca does not leave a white fog, but it does not glue canopies like DPM's MaxFlex ca does. Or try Canopy Glue Formula 560 by Pacer!

I normally use servo screws to fasten the canopy down. Three on each side and trim tape all around. Removable easily.

Jim, is your fogging on the inside of the canopy ?

Pick up a good plastic polish. Pick up a bottle of the polish that guys use for motorcycle windscreens. You may never get it all out. [8D]

Sand the canopy with 400 wet until everything not wanted is removed. Mask the surrounding area and spray the canopy with clear. Any clear you like.
