Guys,
I'm getting an old biplane back in the air and have some light brownish tint on some parts of the white film covering. The ship has been sitting for several years on my rack where the window is and sunlight come in the room. I had flown it for a while as a test bed for and OS 40FS and didn't do a proper cleanup when I was finishe and gotten involved with other more serious ships.
I assume this is old castor that over time just started to darken. I saw a product called Soft Scrub that my wife uses on the Corian countertops. It indicates on the produce that it is for cleaning all type of countertops and plastics. Seems this should work, anyone try this produce?
Best, DennisT

Best cleaner for all types of plastic is Maguire polishing compound. Available at airport and aircraft supply shops.
I've used it to restore plexiglass aircraft cockpit canopies.

Monocote makes their own special polish for film covering. I have used a paper towel wetted with paint thinner or charcoal lighter fluid with some success.

Go outside and use acetone or even alcohol. Make sure use have gloves on. Then I finish with Windex to get the slight scum off the surface. Remember acetone may get to dope finishes if left on too long.

Acetone will get to a dope finish if it even touches it period. Do not slip and splatter acetone with anything close enough to be hit or you will be doing some touch up. Been there done that..
It does work well to clean castor grime off plastic coverings but alcohol is a little safer.

I use to use denatured alcohol for cleaning and it works fine without hurting a dope finish at all. The thing that works best for me now is PB Blaster in a spray can available from Walmart. It seems to cut everything right down to the shine.

And... PB Blaster is one of the best penetrating fluids you can buy for rusted bolts on old cars and tractors. Never thought about using it for a cleaning agent, thanks for the tip.
