Re: acetone and polycarbonate glasses

I have some polaroid polycarbonate (plastic) glasses with some

serious grunge, either they are scratched OR the plastic from the

ear protectors has rubbed off on the lenses (when folded). I am

debating whether to try acetone to clean the spot off but have a

strong recollection that acetone and plastic are not a good idea

(which would explain why acetone is sold in metal containers).



I'm sure someone here knows the answer (It's probably DON'T DO IT)

and thought I'd post the question.



As an observing matter I have had a number of scratched plastic

lenses from looking through my finder, polar scope, etc. and finally

hit upon the expedient of ordering a pair of GLASS LENS glasses

which are much more durable, strictly for observing. My dark

glasses, however, have separate maintenance issues.



thanks

Greg N

Never let Acetone touch Polycarbonate. It will dissolve it. One trick we use

in cleaning boat hatches made of polycarbonate is WD40. I know it sounds

strange but it works. After that just wash with dish soap and water.

I seem to recall that Roland once mentioned that saliva sometimes removed

stuff that wouldn't come off other ways. Try a good spit shine g>.

Never get acetone anywhere near polycarbonate, it dissolves

readily. There is a special polycarbonate polish available but I've

used a simple car body polish and T-cut with some success.
