Wash your hands of woollen top and avoids folding (7)
I believe the answer is:
disavow
'wash your hands of woollen top' is the definition.
I can't judge whether this defines the answer.
'avoids folding' is the wordplay.
I cannot really understand how this works, but
an anagram of 'avoids' is 'disavo' which is within the answer.
A single letter 'w' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'and' is the link.
Can you help me to learn more?
(Other definitions for disavow that I've seen before include "Disclaim" , "To deny support" , "To deny knowledge of" , "Refuse to acknowledge" , "Deny responsibility for (something)" .)
