Sweat on sweetheart: drain deodorant? (8)
I believe the answer is:
toiletry
This might be a double definition.
'sweat on sweetheart drain' is the first definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see an association between them that I can't see?
'deodorant?' is the second definition.
(deodorant is a kind of toiletry)
Can you help me to learn more?
(Other definitions for toiletry that I've seen before include "Something for the bathroom" , "Item used in ablutions" , "Such as soap" , "cosmetic" .)
