Best course to start with as there needs to be a definition of
"clean". Light switches that haven't had a wipe over for a year or so
and are a bit grubby some might consider "clean", to others they
would be "unclean".

In this context the person leaving the property might not even notice
grubby switches as they will have become grubby very slowly and they
won't notice how grubby they really are. Similar on doors edges where
fingers may pull them to a bit shut rather than use the handles.
Handles are like light switches...
