Okay, I'll also admit that I rarely clean my chain. Partially it's because I have a lot of bikes in the rotation, so none gets that dirty, but also mainly because of neglect. I'll lube the chain on my commuter once the squeak gets loud enough to be annoying. I will also wipe a chain down after a ride with lots of salted slush on the roads. But mostly I see chains as consumables, particularly when you can get an SRAM PC-850 for less than $10.
