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.
