If a chain is nasty, I put it in a large pan filled up an inch with gas. I use a stiff wire brush for 5 minutes and it's clean.
What I DO LIKE, is the suggestion that you clean and lube the chain AFTER the ride when the chain is warm. Unfortunately were all tired at that point, err, uhmm, us older guys are tired.........
What I find amusing is that my chain has ONLY fallen off after I lubed it!!! Seems like once it's all flowing freely, you had better have that 1 - 1.250" slack in the center AND at the loosest point and there certainly IS a loosest point somewhere within that chain!
I have a good quality set and they already have about 4 years on them and I do ride, not every day, but fairly often......
I tried to break in TANKS 350X 60$ chain and sprocket EBAY special (after I got done scolding him
) we didn't stretch it much because he's not much of a jumper. Thats fine but the next time he gets it here I'LL STRETCH THAT PUPPY!!!!!!!!! 
CYA guys, I gotta go finish the track............................................. ................................
