I think I asked a question like this as couple of years ago and, like you, got a range of replies. What I took from that thread is that different folks have different needs, and those of a squirrel hunter may differ from those of a dedicated benchrest shooter. I don't mean to say that there are no wrong solutions, but within the universe of correct ones, folks seemed to have adopted the cleaning regimen that fits them. So with that caveat, here's what I do with my .22's:
After each range trip I use a home-made patchworm (weed-whacker line with one end trimmed to sharp and the other melted to stop a patch from falling off) and Hoppes No. 9 -- five or six cotton patches until I have gotten the worst of the crud out. Then a clean patch or two and then a patch with a light coating of RemOil on it. That's it until accuracy starts to fall off. I make sure to pull the nylon line straight out of the bore without touching the crown. Next range trip, I set aside some ammunition for foulers to re-lube the bore. I mainly follow this routine so that I am starting each range trip in more or less the same place and can (hopefully) cut down on my variables from visit to visit. Note: I am a casual plinker searching for best accuracy, not a competitor, so I don't spend any time worrying what the "other guy" is doing. I want my rifles to last a long time and to give good value. I put a clean patch down the barrel before each new shooting session to take up any excess RemOil (don't want to "bake" it into a polymer by firing into an oily barrel or encounter any pressure issues).
Once a year on my birthday, or more often if indicated as above, I will get a bore guide, a coated rod and a caliber-specific brush and/or patch jag and work on any problem areas. I have a bore scope, so I inspect and then clean with Hoppes No.9 and/or Kroil. Inspect again. If the problem persists, I move to a more aggressive ammonia-based solvent, like Sweets. You have to be careful with that stuff -- it will damage your bore if left in too long (or not fully removed, which amounts to the same thing). I have not generally found leading to be a problem, but the bore scope would show it in short order if I did.
That's it. I have a bias towards the least aggressive products I can find. Hoppes No., 9 has been around a long time, so plenty of Beta testers. Ditto RemOil & Kroil.

This is the last area where I want to be an innovator. Slow and steady.
Good luck and report back. I feel like if you tried to compile a data base with RFC responses to this question you'd get a chart with a really long list of techniques/variations on one axis and a relatively small number of adherents to each one (relative to the number of respondents) on the other. However, having said that, I am always surprised how many folks here will take the time to answer a question like this. It is part of the RFC generosity that keeps me coming back.
