Stain spoiled shiny material (5)

I believe the answer is:

satin

'shiny material' is the definition.

'stain spoiled' is the wordplay.
'spoiled' is an anagram indicator.
'stain' with letters rearranged gives 'SATIN'.

(Other definitions for satin that I've seen before include "Stain on silky cloth" , "covered with?" , "Saint (anag.)" , "Smooth glossy fabric" , "Glossy textile" .)

I've seen this clue in The Sun.
