Crossword Genius

Rubber ages Queen (6)

Ross

I believe the answer is:

eraser

'rubber' is the definition.
(rubber can mean an eraser)

'ages queen' is the wordplay.
'ages' becomes 'eras' (I've seen this before).
'queen' becomes 'ER' (abbreviation for Elizabeth Regina).
'eras'+'er'='ERASER'

(Other definitions for eraser that I've seen before include "correction device" , "device for deleting things" , "destroyer" , "One removes writing" , "It could remove" .)

I've seen this clue in The Telegraph.
