Ok Kyle,
The first thing to do is to not panic and jump into a
mechanical repair involving material removal, sanding, polishing.
The first thing I would do is to get a bit of METHANLOL and see
if the film is removable. Methanol doesn't hurt acrylic in the least.
If that doesn't work, ues V&PM Naptha, Use soft cotton to clean it,
I use flannel from Walmart. My experience is that the stuff is usually on
the
INSIDE of the bubble and are products fron the sublimation of the plastics
in the interior of the airplane. DEFINATELY solvent wipe stuff before
you get out the polishing compounds.

Another thing that few bother with is to use a canopy cover to keep dust
off the canopy. Most dust is pretty acidic, remember acid rain and car
paint jobs.
Get a big soft piece of flannel at Walmart and keep it on the plane when you
arent flying it.
Plexiglass generates static electric charges and pulls dust out of the air
when it sits.

Oh Yeah, I make canopies and acrylic stuff for a day job, so you can take
this for what it is worth

Have a great day

I've noticed that the windscreen and canopy on my RV-6 has developed a
haze on its exterior.

The history of the canopy is that the canopy was manufactured about 7
years ago, with the airplane first flying about 5 years ago. The airplane
has always been hangared (other than the occasional overnight stay
somewhere), and has been treated properly during its life. My cleaner of
choice is Plexus, which Aircraft Spruce and several other outlets sell for
aircraft canopies.

The only things I can imagine that could have caused the haze on the
canopy is either the plexus, exposure to corvis oil (the smoky stuff) at
airshows, or some sort of airborne contaminant in my hangar (e.g. a
neighbor spray painting).

For what it is worth, the canopy doesn't have any scratches, so I probably
don't need an aggressive abraisive cleaner.

The bottom line is that I'm interested in removing this haze layer. Any
recommendations?

Thanks,
