Windshield Haze

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,

Actually you do need an 'aggressive abrasive cleaner'...
Whatever is attacking the acrylic is bonded to the surface.. You need
to grind that away and then polish the new surface...

Know any local classic car / hot rod die-hards?

Those folks are often very familiar with all kinds of cool products to
restore mechanical things. Chances are they will know of products and
techniques to get your canopy crystal clear and sparkling. In some
cases, they work with parts that are very difficult, or even impossible,
to replace.

It would be interesting to know if there are any sources of chemical vapors
nearby that could have caused the hazing. If they are strong enough to
damage your canopy, perhaps they are also a hazard to metals and your body.

Hi Kyle

I don't recall the name of the product but it is easy to find - most
Harley dealers carry it and it is for removing the haze and small
scratches from motorbike windshields. It comes in a white plastic
squeeze bottle with red writing. They make one for haze and two for
different levels of scratches. Awesome stuff - takes a fair amount of
work but the results on my old windows was excellent.

You can also use a product called Mirror Glaze. It comes in two flavors,
one in a white squeeze bottle has a mild abrasive for scratch removal.
Another flavor comes in a blue/grey bottle and is for regular cleaning.

You spread it on, let it dry and buff it off. Lots of work, but works well.

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

This was the ticket! We have a brand new Harley Dealership nearby and they
carried their cleaner/polish and their plain 'ol cleaner. The
cleaner/polish really did the job. It took a minute or two to clean each
6"x6" area of the canopy. Afterwards, I followed up with the cleaner, which
is inexpensive ($3.95/bottle) and does just as good a job as the Plexus I
normally use at a fraction of the price. I'd say the pump spray bottle from
the Harley shop has 2x the cleaner in it as an aersol can of Plexus, which
costs ~$8.00 or so.

The cleaner/polish was $5.95/bottle.

Highly recommended for slightly hazy plexi...
