Rise and wash (5,2)
I believe the answer is:
stand up
I believe this clue is a double definition.
'rise' is the first definition.
('stand up' can be a synonym of 'rise')
'wash' is the second definition.
(thesaurus)
'and' acts as a link.
(Other definitions for stand up that I've seen before include "funny kind of act" , "Remain valid" , "Sort of comic (to be counted?)" , "Survive examination" , "Kind of comedian" .)
