Maybe using bleach turned air nasty (8)
I believe the answer is:
sanitary
'maybe using bleach' is the definition.
I can't tell whether this defines the answer.
'turned air nasty' is the wordplay.
'turned' indicates anagramming the letters.
'air'+'nasty'='airnasty'
'airnasty' with letters rearranged gives 'SANITARY'.
Can you help me to learn more?
(Other definitions for sanitary that I've seen before include "Free from dirt or infective matter" , "Free from filth and pathogens" , "Any sitar (anag.)" , "Astray in hygienic way" , "Relating to hygiene" .)
