Engineer left broadcasting, managing to dodge scandal? (6)
I believe the answer is:
teflon
'managing to dodge scandal?' is the definition.
'engineer left broadcasting' is the wordplay.
'engineer' is an anagram indicator.
'broadcasting' becomes 'on'.
'left' is an anagram of 'tefl'.
'tefl'+'on'='TEFLON'
(Other definitions for teflon that I've seen before include "Non-stick coating for pots and pans" , "Non-stick material" , "Non-stick coating (trademark)" , "It's coated on surface to prevent sticking" , "Non-stick coating as for frying pans" .)
