I've not had time to write my guide yet.
For now, do this: https://www.tgrantphoto.com/sales/in...ken-video-head
Scroll down that page to Clean Video Heads.
Why did I change? Because the quality of chamois and foam swabs has gotten worse in the past few years. Too many snags on heads, and even one is too many. So paper from now on.
Note that I'm not fond of paper. It's still fiber, can leave dust. But at least it does not snag.
If you're really protective of your gear, then there are some (now expensive) dSLR sensor swabs that I use. I had a huge stash that I bought 10+ years ago, and am now down to my last box. Only use the Photographic Solutions brand.

But paper is fine, I do that too.
How I disagree/differ from TGrant instructions:
Compressed air is fine. But never let it spew liquid, aka never turn the can sideways or upside-down. It's often required to clean the interior of the VCR with canned air.
For non-head path cleaning, foam swabs work great.
Chamois used to be fine. If you have old-stock chamois or foam, that you know is fine (ie, you've done this before, for years, using the same supplies), then your swabs are fine. If you're buying new swabs, even supposed NOS, assume it's junk.
I must emphasize: gentle
pressure. Don't be a hamfisted brute, but equally don't be a wuss.
It never takes 10-20 pieces of paper. Maybe 3-4 at most.
Isopropyl alcohol dries almost instantly. 30 minutes is silly, 5-10 is more accurate (and even that's being overprotective).
