Back in the day, we used to remove our chains, clean them in kerosene (sometimes in gasoline ) and then heat up paraffrin wax and dip the chain in. The wax would seep into the little nooks and crannies and provide long-term lube. At least that's what we believed.

I'm terribly lax in the chain cleaning and lubing department, too. Probably because I have some mental block stemming from the kerosene and wax days. That was at least a two hour job.
