Crossword Genius

Get rid of mould (4)

Ross

I believe the answer is:

cast

This clue is a double definition.

'get rid of' is the first definition.
(thesaurus)

'mould' is the second definition.
('cast' can be a synonym of 'mould')

(Other definitions for cast that I've seen before include "pitch" , "Personnel in a play" , "Squint to see" , "Pot" , "Throw the actors' group" .)

I've seen this clue in The Telegraph.
