Since I really wanted to try to frame some 
autographed cels over the weekend, please forgive 
me for re-posting these questions:

[1] Is there a way to safely clean off or remove 
permanent ink from acetate (or more specifically, 
duralar, the acetate substitute)?  Permanent 
black marker and permanent gold marker in 
question, particularly?

[2] How does one usually go about cleaning 
dirt/dust off of cels?  (if you know an 
information link, that'll suffice)

After calling a few art stores about the first 
question, I have be suggested the options (which 
you may or may not have experience with): 

(1) Eradicator markers: $1-2 each; apparently 
they can remove Staedtler and maybe Sharpee 
permanent inks.

(2) Nulamar correction pens: $1.50 each; 
apparently does the same thing as above, but I'm 
not sure

(3) nail polish remover: although I was warned 
that this might affect the acetate somehow

If you are experienced with these solutions or 
know even better methods to clean permanent ink 
smudges off of acetate, please let me know.

THANKS!!!

OH, AND IF YOU'RE BORED/CURIOUS, THIS IS MY STORY 
(previously posted):

To my horror, I discovered that 2 autographs on 2 
cels (1 autograph per cel) were slightly smudged 
in the course of transporting my hoarde home from 
AX (I've been too busy to check up on them until 
now).

Would any of you cel experts or artists know how 
best to clean up the smudges so that I can 
restore each autograph's original lines?  The 
smudging is not major, but I'm planning to frame 
these babies really soon and I want to make the 
presentation as well as possible.

The first autograph was written with permanent 
black ink while the second was written in that 
gold ink, if that helps in any way.

Thanks ahead of time!
