Since I live in a relatively dry climate, I use a paraffin-based one-step chain cleaner and lube. In more than 100K miles of cycling, I have had only one roller on one chain freeze up, and I get a lot of service out of a chain before it reaches Sheldon's 0.5 percent elongation standard for replacement.
