I de-grease chains when new (to remove packing grease), but that's it - no extra cleaning.
Plug in the crock pot, let the wax melt, break the chain, dip it in for 30 minutes, fish it out with a metal clothes hanger, give it one single wipe, let it dry and re-install. Once every few hundred miles. So easy. So clean.
