I'm restoring an old Duncan Phyfe type of drop leaf table and have run into some stubborn stains. I have stripped the finish and used mineral spirits for cleanup. Oxalic acid was used on a few dark (black) water stains with some success. I tried a small oxalic acid test on the edge of the stains In question with no noticeable change.
I have a few photos of the stains online--

Any advice on what to try next? Will some heavy oxalic acid washes (water) hurt the veneer? The veneer is tight to the wood and in great shape except for the stains and a few dings and scratches, it will need very little sanding.

| You could try a wipe down with a rag dampened (not wet) with laundry bleach. This won't hurt the veneer or glue, and should get rid of the stains.

Thanks. I'll try bleach after a bit more work on the veneer. I'm still trying to remove what's left of the finish and the brown stain/dye from the veneer. When I get all three top pieces the "same" I will try a bleach wipe.

Good to see the forum back. I put this restoration project off for awhile, just now working on it again.
I have one stubborn stain that will not go away. Tried oxalic acid months ago and bleach the last few days (2 coats yesterday and one today) I just gave it a wipe down with baking soda, looks like household bleach will not work on this one stain but it did a great job on the rest of the top walnut veneer. I'm ready to sand and finish, any idea what to try next on this stain?
Attaching a photo of the stain.

| My only 2 thoughts are pool chlorine or hydrogen peroxide.

Thanks again. Can hydrogen peroxide be used for a "spot" stain removal or would the whole surface need a coat?
I no longer have the option of not staining the walnut veneer, I sanded through a very small area of the veneer at a spot I used dyed gun stock bedding compound to fill a small area on the top edge. Too bad, the bleach removed all the old red dye and it was looking very good.

| I'd try it as a spot remover.
