[oletrucks] Parts cleaning solvent?

["Stephen" <slb1@humboldt1.com>]

Hello,

I have just purchased a 20 gallon parts cleaner and would like to know what
solvent is recommended?  My preference is for something non-flammable and
non-toxic if possible.   Also, what sources are available for the solvents?

Thanks much,
