Wood preservative (8)

Ross

I believe the answer is:

creosote

'wood preservative' is the definition.
(I've seen this before)

This is all the clue.

(Other definitions for creosote that I've seen before include "Fencing gear, perhaps" , "Preserve deal, say" , "Dark oily liquid, preservative for wood" , "Oily liquid obtained from tar" , "Oily liquid for preserving timber" .)

I've seen this clue in The Independent, The Guardian, The Times and The Mirror.
