Honestly unless you believe there is inherent good in doing that (religion mostly, morality for some) then no. It doesn't make sense to work for free, to not have returns.

If recognition is a form of payment then good on some people, though I personally think recognition can be a drug, and religion justifies my good actions for me much better.

Point is keep on doing good, and maybe consider that the slightly tidier and cleaner space you leave was worth the effort. Surely someone would have seen you and thought "damn, I should do that next time"
