Free from germs (7)
I believe the answer is:
aseptic
'free from germs' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aseptic that I've seen before include "avoiding germs" , "Free from bacteria, surgically clean" , "Sterile" , "Free from bacteria, surically clean" , "ideal conditions for hospital?" .)
