Cleans cuff of special suit when changing hands (6)
'cleans' is the definition.
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for scrubs that I've seen before include "special clothing for those working in the theatre", "Abolishes", "Clothing worn in an operating theatre", "Protective garments for surgeons", "Wormwood _____".)
