I put a small oak picture frame down on a bench that had a little walnut
sawdust on the surface, and it caused a dark discoloring. Can I get that
out?

Surprised it would actually stain unless one or the other (or both) were
awfully damp...but, that aside, a little oxalic acid should do the
trick...

Probably not - tannic acid is a very good stain. Might not be too deep,
though, so sanding might be an option for you?

Not really. The frame is already stained and I don't think I can match the
stain after sanding. Fortunately the discoloration is only on the edge
because the frame was standing on edge when it happened.

Thanks.

Since the piece is already stained, anything that would lessen the
discoloration from the walnut is likely to lighten the stain as well. I
turn walnut on the lathe, and get stained hands. Only things that get
it off are bleach and Oxy-Clean.

No - "vandyke crystals" are a well known stain - they're made of
walnut husk extract ! You _might_ bleach it out with a hypochlorite
bleach (common household bleach), but this is more likely to cause
more unevenness than it solves. You can always sand it, if there's
suitable access.

I'd make a weak solution of vandyke, or walnut sawdust, in water and
stain the rest of the frame to match. It's a close enough colour match
that oak shouldn;t look out of place with it.
