Cleaner is Henry dressed in women’s clothing (7)
I believe the answer is:
dishrag
'cleaner' is the definition.
(I've seen this before)
'is henry dressed in women's clothing' is the wordplay.
'henry' becomes 'h' (symbol for the unit of electrical inductance).
'dressed in' means one lot of letters goes inside another.
'women's clothing' becomes 'drag' (I've seen this in other clues).
'is'+'h'='ish'
'ish' put within 'drag' is 'DISHRAG'.
(Other definitions for dishrag that I've seen before include "Washing-up cloth" , "American tea towel" , "used to clean in kitchen" , "Wiper in the kitchen" , "Cleaner" .)
