My wife left a wet steel tray on a piece of solid oak for two days. How can I remove the resulting black stain without removing too much of the surface of the oak?

Try oxalic acid. Do a search on previous threads for further details: some cover its use on GRP, others its use on wood.

Since oxalic acid seems to be difficult to find in the UK you may want to try this link

I got my last lot of oxyalic from Boots.

OXALIC ACID

Others have had difficulty getting any pharmacy to get it for them so I guess you were lucky.

It seems to depend -- here, at any rate -- on which wholesaler the pharmacy uses. My local chemists are 50 yards apart. One can order oxalic acid, the other not.

You'll find that oxalic acid will also prevent such stains occurring in future -- if administered liberally to your wife. V poisonous (the acid, not your wife)
