How does one wipe clean and oil the chain? (maintenance details) This may sound like a dumb question -- I know how to oil a bike chain, but apparently not how to do it correctly.
I have a relatively new gravel bike, a Giant Revolt, which I ride (on tarmac) about 25 km a day and whose chain I've been oiling regularly, about every 2-3 days, just as I'd done with my previous bike, a mountain bike.  I took my gravel bike in for maintenance and they said I was overdoing the oil, that in fact it was better too dry than too wet.  What they said I should do is -- after every ride -- clean the chain with a towel and then oil it &quot;lightly&quot;.  What's &quot;lightly&quot;?  &quot;One drop&quot; they said.  For the entire chain?  I doubt it -- but I'm not sure what they meant exactly.  (I should have asked when I was there, but now, given Covid, it's very hard to get in touch with them again -- we have to make scheduled appointments to see them).
I'm looking for 'easy daily' maintenance -- not 'thorough' chain cleaning, as I've read about in other posts.  Just enough to keep things clean and well-oiled, that is, getting the chain clean with a towel and then lubricating it again.  I guess the crucial question is &quot;how much oil?&quot;
Again, in some ways this is a very simple question, but the devil lies in the details, and that's what I'm not clear about.
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.
