Just dunk it in a bowl or something and rinse well afterwards.
You'll need to relube it properly though.
If it's just to remove surface crud, I wouldn't go so extreme though.
Ive got some Gunk that i used to de-grease oil from my car engine.
I had a jar of white spirit I dunked it and then dryed it off the relube it it took about 2 mins to do !
