What will help one stay clean in dodgy stand-up (7)
I believe the answer is:
dustpan
'what will help one stay clean' is the definition.
(receptacle for collecting dust or dirt)
'dodgy stand-up' is the wordplay.
'dodgy' indicates an anagram.
'stand-up' becomes 'standup' (synonyms).
'standup' with letters rearranged gives 'DUSTPAN'.
'in' is the link.
(Other definitions for dustpan that I've seen before include "domestic utensil" , "Sweeping receptacle" , "Receptacle for sweepings" , "Cleaning aid" , "What's frequently found by a brush -- stand up (anag)" .)
