Cancel clean-up (5)
I believe the answer is:
scrub
I believe this is a double definition.
'cancel' is the first definition.
(scrub can mean to cancel or erase)
'clean-up' is the second definition.
(I've seen this before)
(Other definitions for scrub that I've seen before include "Powerful wash" , "Stunted growth" , "remove cosmetic" , "Rub hard; brushwood" , "insignificant type" .)
