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

Hot tanking was the best way to go 20 or so years ago, now it's not nearly as good because of the environmental solvent restrictions imposed on the use of good working stuff. It might be better now to do it the DIY methods and then burn out the remaining seam grease/oil. After I had mine hot tanked a couple years ago I still had to do a home solvent scrub and clean, flame burn and wire wheel to make sure it was as spotless as I could get it. Still it had a pocket or two of grease spots along the seam that didn't like welding so much. Hey...we do the best we can.
