You can set an unrealistic standard of cleanliness, like: polishing doorknobs, cleaning windows, the roof and the basement every day. Or do your cleaning routine twice per day, or 3 times... when does it stop?

Then, at some moment cleaning has diminishing returns and becomes redundant. Plus, day to day activities may require to make things dirty temporarily, and wanting to preserve a permanent state of cleanliness may interfere with those activities.
