Uses an aerosol (6)
I believe the answer is:
sprays
'uses an aerosol' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sprays that I've seen before include "Jets of vapour" , "bunches of flowers" , "Sprinkles with bouquets" , "Disperse in droplets" , "Disperses water in very small drops" .)
