When I’m in a public washroom or office building and I see a cleaner I say ‘thank you for cleaning up after us’. 

99.9% of the time it’s likely a thankless job..

I wouldn’t say that I go that far, but I clean up the restroom (yes, even if it’s not mine- within limits!) and always acknowledge those attending the space.  Hi and all. 

Maybe just my weird brain, but what you do may come off as condescending.
