Fungu Stain

[TOMARTOM]

I have in error late last night framed a piece of three ply with a blue/grey stain on part of the surface.(presumably a fungus) on a sideboard currently being made.

Is there any way a bleach could reduce the stain without damaging the wood(please provide info if possible).

Sincerely

Tony

If its consrtuction grade ply sometimes the adhesive shows through as a bluey sorta colour.

Hi Tony
I'd try hitting it with some oxalic acid just in case it's a water stain, you won't harm the ply by doing so.
