bp clean up, hot water or cold?

I routinely use about a double shot of Murphy's Oil Soap, in a 3# coffee can of near-boiling water, anytime I thoroughly clean my front loaders. The metal gets hot enough to almost dry itself, or you can dry them off with a hair dryer, etc. The Murphys forms a protective coat that lasts weeks or months. Been using it for ages.

This provides sufficient volume to submerge the cylinder & Barrel (one end at at time) so they can soak a few minutes. With rifles, I pull the barrel off, unscrew the nipple and then submerge the breech end in the solution. Using a tight patch, pump the hot solution in and out of the bore. The very hot water and Muprhys work together as a hellacious crud cutter, combined with the patch.
