Cleaner finds it is more sensible going outside (9)

Ross

I believe the answer is:

sanitiser

'cleaner' is the definition.
(something which cleanses)

'it is more sensible going outside' is the wordplay.
'more sensible' becomes 'saner'.
'going outside' means one lot of letters goes inside another (the word goes on the outside of inserted letters).
'it'+'is'='itis'
'itis' inserted within 'saner' is 'SANITISER'.

'finds' is the link.

(Another definition for sanitiser that I've seen is " One making (something) clinically clean".)

I've seen this clue in The Guardian.
