Just me,
1. New folks I am assisting do the inspect and maintain, and cleaning if need.
Mentors had me do this, so I pass forward as passed to me.
2. Let gun smith do the inspect, maintain, clean if need and while they do that, I drink their coffee, eat donuts, mess with the dawg, and go shoot some gun they have with their ammo.
(or customer's gun and ammo to assist gun smith by me shooting and seeing if anything was overlooked, or just to give feedback).
3. Most folks over clean, and/or use improper methods no matter what cleaning kit they have.
If they ever quit making pipe cleaners, and toothbrushes, I am in a world of hurt.
