Not acceptable for something to ignore basic hygiene (2,4,4)
I believe the answer is:
it wont wash
'ignore basic hygiene' is the definition.
I know nothing about this answer so I can't tell whether this works.
'not acceptable for something' is the wordplay.
I cannot really understand how this works, but
an anagram of 'not' is 'ont' which is within the answer.
'something' could be 'it' (both can refer to an object) and 'it' is found in the answer.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Other definitions for it wont wash that I've seen before include "You'll have to think of a better tale than that" , "Unconvincing reason" , "why soap is discarded" .)
