We have a standard 30gal. drum-mount parts washer. The company that did the last drum/solvent swap is no longer in business, and everyone else we've talked to (Safety-Kleen and Crystal Clean) wants to put us on a recurring contract. Even the longest one year interval is huge overkill for us, as we sometimes don't use the washer for months at a time.
The tag on the existing drum indicates the solvent is petroleum naphtha.
Looking and asking around locally, we've had people say they run:
1,1,1 trichloroethane (yeah,... no,... much as we'd like to, not going there...) ;
Mineral spirits is all I use at my shop in the parts washer. Has a low flash point, so little fire hazard and is inexpensive. Works just fine. If you know anyone with a waste oil heater... they will gladly take away the old solvent when ready to change out the fluid.
Stay away from diesel! Stuff is evil and skin exposure will shorten your time on earth. Doesn't clean well at all, and deteriorates with age into a smelly lot of dirty oily junk. I'd imagine kerosene to be similar. Mineral spirits (keep covered when not in use) is the much better option.

I highly doubt you can get trichloroethane even if you tried. Whoever you spoke with probably meant trichloroethylene. Still nasty stuff but not nearly as bad and as near as I can tell is still commercially available.
Mineral Spirits is usually the best choice followed by kerosene. Difficult to find in bulk though.
20 yrs ago I bought 20 gallons at a filling station in Simi Valley, CA. for $4.00 a gallon. I wish I could find it somewhere here in GA.
