Get up about mid-morning and wash (5)
I believe the answer is:
rinse
'wash' is the definition.
(rinse is a kind of wash)
'get up about mid-morning' is the wordplay.
'get up' becomes 'rise' ('rise' can be a synonym of 'get up'**).
'about' means one lot of letters goes inside another.
'mid' says to take the centre.
The centre of 'morning' is 'n'.
'rise' placed around 'n' is 'RINSE'.
'and' is the link.
(Other definitions for rinse that I've seen before include "Use water to remove soap" , "Cleanse in water" , "Swill out" , "Run water through" , "Hair colourant" .)
