Run through advice for deployment of parasol? (3,2)
I believe the answer is:
use up
'run through' is the definition.
(synonyms)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for use up that I've seen before include "Entirely consume" , "Expend" , "Exhaust (resources)" , "Finish, exhaust" , "Completely consume" .)
