Here is a link describing health and environment risks of trichloroethylene: http://www.atsdr.cdc.gov/tfacts19.html I think Kodak used to bottle this as a negative cleaner, but can no longer find it. I would not think one would use any of these extreme washing techniques routenely. Try a brush or puff of air. [Has anyone ever found an "antistatic" brush that actually works?] Save the more aggressive stuff for something that is really grunged up.
