Nick’s small cloth (5)
I believe the answer is:
swipe
'nick's' is the definition.
(I've seen this before)
'small cloth' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'cloth' becomes 'wipe' (piece of cloth used to wipe things down).
's'+'wipe'='SWIPE'
(Other definitions for swipe that I've seen before include "Steal; criticism" , "Half-inch" , "Hit with swinging blow, or slangily steal" , "Put (card) through reader; take without asking" , "Pilfer" .)
