Solo sort needs bleach or explosive (8)
I believe the answer is:
bachelor
'solo sort' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'bleach or explosive' is the wordplay.
'explosive' is an anagram indicator.
'bleach'+'or'='bleachor'
'bleachor' anagrammed gives 'BACHELOR'.
'needs' is the link.
Can you help me to learn more?
(Other definitions for bachelor that I've seen before include "Unmarried person" , "Unmarried male" , "Single person" , "Single man" , "Graduate" .)
