I have been reading some scary stories about Simple Green and SRAM chain failures [Bicycle Science, via Sheldonbrown.com]. Personally, I do not believe in cleaning chains, other than to wipe them down with a rag or toothbrush, and I never disassemble a chain except to replace it. I use White Lightning, which is adequate in my dry, moderate climate.

By the way, Sheldon recommends replacing any chain that has elongated by 0.5 percent, i.e., 1/16" per foot (24 half-links).
