Remove moisture around electronic circuit leads (6)
I believe the answer is:
decamp
'remove' is the definition.
(to remove from a location is to leave it)
'moisture around electronic circuit leads' is the wordplay.
'moisture' becomes 'damp' (I've seen this before).
'around' indicates putting letters inside.
'leads' suggests taking the first letters.
The first letters of 'electronic circuit' is 'ec'.
'damp' going around 'ec' is 'DECAMP'.
(Other definitions for decamp that I've seen before include "Make off - from tent?" , "Fold up tent and depart" , "Split" , "Make sudden breakaway" , "Abscond" .)
