I have a piece of 2x8 Southern Yellow Pine that forms the back slab of
the bench I am building. I picked this board because it was straight,
knot-free, and had consistent grain direction for planing. And the
"dirt" on it would come off as I dimensioned it, right? WRONG!
I now have what looks like mildew--a grey staining, primarily in the
early wood. Too late to replace it in my project (at least without a
chain saw), and I'm wondering what to do now. I have a cutoff to
experiment with. Resawing a small piece showed the grey stain to be
throughout the wood, not just on the surface.
A dilute Clorox solution had no visible effect. Should I try it
straight? Would wood bleach (oxalic acid?) do anything? My concerns
are primarily to kill whatever this is if it is alive, so that I don't
have spores possibly causing health problems, or something eating the
wood. Only secondarily, I would like to get rid of the stain for
Planning to use either tung oil or BLO when bench is finished, if that
makes any difference.
Thanks for any advice, or pointers to sources of information.
