Interesting points. Honestly, it seems like mountains out of mole hills: there are worse things here to argue about over the safety of the anonymous internet.
After all the influence, I'd still stick with my original plan: I help clean after all the passengers are off. I figure I do this 1 in 5 legs because it is not required on RONs and many places where the aircraft has to be inspected. I don't do it if I am late for a commute(but explain to the FAs why). Most of the time, I am cleaning on a flight I commuted on, again not if it was an RON or I am late.

As a mid level guy here, I am fascinated by the current disjunction of almost everything in the pilot world. One of the biggest polarizers is this cleaning thing. I have flown with guys who insisted we clean, had Captains on my commute chide me for not cleaning even though we were late and I had to run for my working flight. Reciprocally I have gotten as little as frowns and as much as a "jet-bridge talking to" for cleaning on a commute. It is somewhat frustrating to always be in a battle about this and much more distracting than crossing a few seat belts and grabbing maybe 4 pieces of trash out of seat backs. Just my .02.
