It should. It worked for me on a Parker stock. I used Oxalic acid which can be bought at most paint stores. It bleaches the area without affecting the wood. Just take a quarter teaspoon of the crystals in half glass of warm water (if they don't give directions) I used a Q-tip to apply but you can use a rag. Although it won't be strong in that concentration, latex gloves are advised as is eye protection. I did not rinse and it was fine but a damp paper towel is probably a good idea.
It took a minute to work and I was amazed.
