Gulf wax in a Little Dipper crock pot. Less trouble than oiling from a bottle. Cleaner too. I can handle the chains with bare hands, just wipe off the shmutz with any scrap of paper -- it's like graphite dust, not grimy.

I've recently added Boeshield T-9 to refresh the waxed chain. It works, is clean, but more trouble. I'll save the Boeshield for cables and other stuff. The wax works fine. The Boeshield refreshed my older cables and housings that were sticking from using Park CL-1. The Park is only a chain lube. As it dries it gets gummy, which resists water and lasts longer. But it's unsuitable for other purposes.

I swap between two identical waxed chains about once a month. Fire up the crock pot every two months to dip both. Not much trouble.
