I decided to try and frame some cels myself.  I 
noticed that the plexiglass I bought is a little 
dirty and could use a cleaning.  Some of the cels 
have inking on the front and I know that it will 
touch the glass.  What could I use to clean the 
glass and won't leave harmful residue which could 
hurt the ink on the cels?
I was thinking of using a mixture of water and 
rubbing alcohol...
Thanks for any help you can offer.
