Clothworker's protector brought him bleach bottles (7)
I believe the answer is:
thimble
'clothworker's protector' is the definition.
(a thimble protects a finger when sewing)
'brought him bleach bottles' is the wordplay.
'bottles' indicates the answer is hidden within the clue (bottling is a kind of containing).
'THIMBLE' is hidden within 'brought him bleach'.
(Other definitions for thimble that I've seen before include "Sewing tool" , "Cover for finger when sewing" , "Caucus-race prize (Alice)" , "Finger-guard" , "Belt him, carrying finger protector" .)
