The heated cleaning system sounds like a killer tool.
How about using a solvent tank with spray nozle? I know those tanks usually use an oil-disolving solvent for greasy auto parts, BUT the question is… could you safely use acetone in it instead. Acetone is the solvent most of us use for cleaning resin off tools and spray guns.
Get a hold of Safety Clean or look in your local phone book for businesses that deal with solvent tanks and industrial cleaning systems… possibly they offer a cleaning system for composite shops. The nice thing about those companies is they service the equipment for you.
my 2 cents.
