I've been reading some of the chain lube threads and there seems to be two schools of thought. Lube frequently and don't clean, or clean frequently and lube as well. Personally I like the lube frequently and don't clean purely due to reasons of laziness. But is there logic behind not cleaning the chain? My neighbor who builds race cars and generally knows his shit keeps his chain spotless to the point you could floss with it if you had big shreck teeth. So now I'm thinking should I be keeping it spotless as well? Is there reasons not to have a spotless chain...is there such a thing as too clean?
