You can buy parts washer solvent like the kind that's used in Safety-Kleen machines. I last bought some way too many years ago to remember its brand name. Some mechanics use Stoddard solvent. Just GOOGLE parts washer solvent.
I too use gas and 2cycle mix in a stainless dog food bowl at work.
At home I use a Safety Kleen type machine with actual safety kleen solvent.
It ain't rocket science!
