I drip 10 or so drops of tri-flow on a shop rag, grip the chain with the rag, and run it through a few times. This gets the chain clean and lubed at the same time. About once a month I use the park chain bath tool and really get it clean, and then relube the same way. Haven't had a chain tattoo since I started doing it that way. My pedals are another story---they give me real tattoos from their sharp edges.
