It is not necessary to clean things that are not dirty. Sometimes, all that is needed is a touch-up. You do not need to dry-clean a suit when it only has to be aired, brushed, or pressed. If there is a hand print on and otherwise perfectly clean mirror, don’t feel you have to clean the entire mirror; just attack the hand print and be done.
Surfaces that you and your visitors can’t see like the top of a cabinet, don’t have to be cleaned regularly. Put some paper down, and when it gets too dirty, pick the paper up and throw it out.
