Finding a warm body to drag a tepid rag around your countertop is easy, sure, but finding someone who's 1) consistent 2) always on-time and 3) not $100/hr is next to impossible.
Perhaps in a large metro it's easier, but I've had basically no luck in suburban silicon valley.
I live in Silicon Valley now. . . found the best cleaner I've ever had. Very happy with her and her helper's work.
Back in the day I had a cleaning service that I trusted and used regularly put a wet rag on top of a CSU/DSU [1]. Not something that I ever thought could happen. Ironically the spare CSU/DSU was sitting right next to that. (Cold and ready to be put in service if the main one failed.) There were of course vents on the top. That's where the rag went. And I was near the equipment at the time (I would never let a cleaning service in where there was sensitive equipment without being onsite).
