White Snake get to grips with most of the buzz to get clean?
I believe the answer is:
wash up
'clean?' is the definition.
(thesaurus)
'white snake get to grips with most of the buzz' is the wordplay.
'white' becomes 'w'.
'snake' becomes 'asp' (asp is a kind of snake).
'get to grips with' means one lot of letters goes inside another.
'most of' means to remove the last letter.
'the buzz' becomes 'hum' (I've seen this before).
'hum' with its last letter removed is 'hu'.
'asp' placed around 'hu' is 'ashup'.
'w'+'ashup'='WASH-UP'
'to get' is the link.
(Other definitions for wash up that I've seen before include "Perform domestic chore" , "Do some work after dinner" , "do housework" , "Clean dishes and cutlery" , "work in kitchen" .)
