Get rid of press as rubbish (5,4)
I believe the answer is:
scrap iron
'rubbish' is the definition.
(I've seen this before)
'get rid of press' is the wordplay.
'get rid of' becomes 'scrap' (I've seen this in another clue).
'press' becomes 'iron' (ironing is a kind of pressing).
'scrap'+'iron'='SCRAP-IRON'
'as' is the link.
(Other definitions for scrap iron that I've seen before include "for recycling" , "Waste metal for melting down" , "Discarded metal" , "rubbish" .)
