Parts Cleaner

List,

I just bought another parts washer to replace the previous one that
was rusted out by using an aqueous based cleaning solution.

My initial intention was to use diesel fuel this time, despite the
odor. Stoddard is now somewhat difficult to find here in California,
and even harder to dispose of when dirty.

What is everyone else using....any suggestions as to alternatives to
either diesel or water based cleaners, which I will not use again?

Thanks,

               Bill
