Los Angeles strip is cleaner (9)
I believe the answer is:
laundress
'is cleaner' is the definition.
(I've seen this before)
'los angeles strip' is the wordplay.
'los angeles' becomes 'la'.
'strip' becomes 'undress' ('undress' can be a synonym of 'strip').
'la'+'undress'='LAUNDRESS'
(Other definitions for laundress that I've seen before include "Disguise for jailbreaker in famous tale" , "Woman washing clothes" , "Woman who washes clothes for a living" , "Washerwoman" , "Cleaner" .)
