Wash out and see clean, perhaps (6)
I believe the answer is:
cancel
'wash out' is the definition.
The definition and answer can be both to do with contact as well as being verbs in their base form.
Perhaps there's an association between them I don't understand?
'see clean perhaps' is the wordplay.
'see' becomes 'C' (the word for the letter, according to Chambers).
'perhaps' is an anagram indicator.
'clean' with letters rearranged gives 'ancel'.
'c'+'ancel'='CANCEL'
'and' is the link.
Can you help me to learn more?
(Other definitions for cancel that I've seen before include "Annul; negate" , "Go for an annulment" , "Cross out or annul" , "Discontinue" , "Officially prevent happening" .)
