Post Subject: Black water stains on wood

Hi Tony, We recently had a small water leek which we have cured. However it has left a black stain on the Oak ply lining, where it soaked in behind where there is no varnish to protect it. The stain is only about 30mm in diameter but unsightly. Do you know of any products or the best way of getting rid of the stain? I know I will have to probably remove the varnish from on top of it first. Thanks. Regards Steve

Dear Steve. You may be able to get rid of the stain by simply removing the varnish and sanding it but take great care not to sand through the oak veneer. I think the acid in oak will cause black marks when it gets wet and is in contact with iron (steel), so if its around a steel pin you may have problems. You can buy special preparations usually containing oxalic acid to remove black water marks on wood, but before you do that apply a little bleach to a small part of the stain because if its is fungal spoors or mould bleach may well sort it out but there again it may leave you with a light patch.
