In the kitchen there is a nice wood worktop which has turned black

block work surface and far to good for a rental. Light colour.

Anyway, once the wood has been soaked long term and turned black is
there much that can be done to revive it?

Yes - Oxalic Acid . Wash several times with a solution of Oxalic Acid
will remove the black and restore the colour.


Any suggested source? I see Wickes do Kilrock Bar Keepers Friend - would
that be up to the job?

(I've a situation similar to the OP's - left a tin on the worktop, and
it's somehow left a black imprint in the oak)

Oxalic Acid is available on Amazon.

Next question is how much I would need!

It isn't expensive, but probably not something to have lying about for
many years.

100 grams be enough?

Probably - if you look at the way he uses it in the videos I posted, a
scoop of it is usually enough.
