CHAIN MAINTENANCE video

I do a lot less than this guy does and my chains still last many years and many thousands of miles.

Notice that the solvent is put on a rag, not applied to the chain directly. That said, I've sprayed my chains directly with WD40, still no premature failures. But seems more prudent to only apply solvent to rag, then wipe chain.

Likewise, lube is only applied to the roller. I've done this part naturally with no coaching since I was six yo.
