Do not read about personal freshener (9)
I believe the answer is:
deodorant
'personal freshener' is the definition.
The definition suggests a singular noun which matches the answer.
'do not read about' is the wordplay.
'about' indicates anagramming the letters.
'do'+'not'+'read'='donotread'
'donotread' anagrammed gives 'DEODORANT'.
Can you help me to learn more?
(Other definitions for deodorant that I've seen before include "Underarm spray, perhaps" , "hum suppressor" , "Toiletry product" , "Substance that removes unwanted smells" , "Smell masker" .)
