Pickle skin (6)
I believe the answer is:
scrape
This clue is a double definition.
'pickle' is the first definition.
(thesaurus)
'skin' is the second definition.
('scrape' can be a synonym of 'skin')
(Other definitions for scrape that I've seen before include "Rasp or abrade" , "Tricky situation - graze" , "Bow and . . . . . ., to be servile" , "Informally, an awkward situation due to rashness" , "jar" .)
