How does one wipe clean and oil the chain? (maintenance details)
Wipe the chain down with a rag to remove dirt and old lube.
Apply lube while spinning the chain. I tend to use quite a bit (a small drop on every second chain link or so). It’s cheap and the next step takes care of any excess.
Wipe down with a rag before the next ride.

In dry weather it can be sufficient to do step 1 only and skip applying new lube for a couple hundred kilometers. It can also be a good idea to use “dry” or “wet” lube depending on the season.
Edit to answer the comment: “Dry” lube is less sticky and good for dry environments where sand and dust sticking to the chain is your main concern. “Wet” lube is stickier and more viscous, best for wet weather because it’s not so easily flushed out of the chain.
