I have a 40 x 50 inch print, mounted to gatorfoam and covered with a clear laminate. It's about 10 years old and has held up well, but enough grime has built up on the surface now to really dull the print.
What's the best way to clean the surface without doing any harm? I don't know the specifics on the laminate, but it's a typical product used for protecting display prints and transparencies from handling and UV.
Any thoughts?
