Tammy,

Athey et al. described a paint gun cleaning system designed to reduce by 75 
% the amount of solvent needed to clean the equipment :

Athey, C.; Hester, C.; McLaughlin, M.; Neulicht, R.M.; Turner, M.B. (1988) 
Reduction of Volatile Organic Compound Emissions from Automotive 
Refinishing. Control
Technology Center; U.S. Environmental Protection Agency (EPA-450/3-88-009), 
Research Triangle Park, N.C. (NTIS No. PB-89-148282)

For metal cleaning before painting, try the Solvent Alternatives Guide 
(SAGE) : http://sage.rti.org/
and the Parts Cleaning Web site : http://www.partscleaningweb.com/index.cfm

Consider aqueous cleaning :
