Did the dishes, exhausted (6,2)
I believe the answer is:
washed up
I believe this clue is a double definition.
'did the dishes' is the first definition.
(I've seen this before)
'exhausted' is the second definition.
(I've seen this before)
(Other definitions for washed up that I've seen before include "Done for - cleaned dishes" , "Carried ashore by the tide" , "no longer effective?" , "No longer successful (colloq.)" , "Defeated or failed - left on shore? (6, 2)" .)
