I believe the answer is:
wash up
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">do the dishes</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for wash up that I've seen before include "do housework" , "work in kitchen" , "Debrief session" , "Do some work after dinner" , "'Clean the dishes (4,2)'" .)
