back to the lube topic...
I clean the chain with a kerosene soaked rag, then re-oil with a silicone based lube... If the chain is particularly dirty, I will use kerosene in a trigger type spray bottle to clean it even better before re-lubing...
I do believe that most of the function of lubing is to keep the grit away from the o-rings... You want to clean the chain, but not with a solvent, because you need to leave a layer of something to stop things from rusting... then you want to keep a layer of something, to stop things from rusting, and also so that when it heats up, it will run towards the seals...
but IMHO you don't want 'oil or grease' because it attracts and retains dirt and grime, and that too works it's way into the o-rings, breaking them down, and letting the most important grease out resulting in eventual chain failure...
You also want the chain to slide on and off the sprockets with minimum friction, so the layer of something needs to the a lubricant as well as a rust barrier...
I don't like the idea of WD40, because it washes the other lube away, and therefore the only lube left is the thin layer of very fine WD40 oil, which also builds up grime very quickly...
I reckon that a silicone spray fits the bill pretty well...
Cheers,
Daewoo
