Rubber taint from tea strainer? (6)
I believe the answer is:
eraser
'rubber' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for eraser that I've seen before include "Correcting implement used in drawing or writing" , "Rubbing-out device" , "One who removed" , "India rubber" , "Stationery item" .)
