An anti-fog device that can get rid of men? (8)
I believe the answer is:
demister
'device that can get rid of men?' is the definition.
'demister' can be an answer for 'device' (demister is a kind of device). I'm unsure of the rest of the definition.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for demister that I've seen before include "control of car" , "Device for removing condensation from a windscreen" , "Remover of condensation" , "one good at clearing" , "One gives a clear view" .)
