Is there an easy way to degrease and de rust a K frame?

Also, FWIW, there is a place here called Industrial Chrome with a big oven that gets really hot and parts like a K member will come out with all grease, grime and paint gone (inside and out); having turned to ash. They are always willing to take on a part like a K member with the understanding that it might be a few days before they have room to squeeze it into the oven with another load.
