I don't have a parts washer, I use a 5 gal busket
Kerosene works good for me, had to scrub some of the stuff on my knuckles, and it eventually eats the $3 yellow kitchen gloves.
I wash it all down with brake cleaner afterward.
but!
when I'm done I throw the whole mess, used grease and all into the oil tank and burn it in the furnace in the house
re-cycling is goooood
used motor oil goes in there in small amounts also
