Q: I use an acetate film to protect my watercolors when I present them to clients and when I store them. Often, I use Windex to clean off fingerprints on the acetate. Do the chemicals in the Windex pose any problems to the pigments on the paper?

A: The chemicals in the Windex do not pose a problem to the watercolors if the acetate is wiped completely dry before it is replaced on the surface of the artwork.

In answer to your question in regards to the use of Windex on plastics and acrylic glazing.
If the artwork is already wrapped in the acetate.
It is best not to use an amonia based cleaning product on artwork that has been covered in acetate or glazed under plexi- glass, because the amonia cleaning agents produce a gas that can be absorbed into the weave of the paper, thereby causing a shortening of life expectancy in the paper product.. To clean the plastics with out harmful residue I would recommend using a non- amonia or specific plastic/plexi cleaner...Make sure that you wipe the cover completely dry!!!!Otherwise the liquid may get inside your wrapping!
Also to remove sticky residue on acrylic glazing such as plexi glass try using Isopropenol alchol. This will also help to remove light scratches from the surface of the glazing with out damaging the artwork below.
