Little black spots in wood. How do I get rid of them?

CapnJim, there is also another solution which works quite well no one has mentioned. As your timber is all WWII era beechwood, why not duplicate the darker tone stain used during WWII on BSA made SMLE components? If the spots really bother you, you can always give it a coat of Fiebings leather dye. A mixture of Fiebing's "Chocolate" and "USMC Black" dye will work perfectly. Just get the stocks cleaned of all grease, allow to dry after a soaping down, then apply a coat of the aforementioned dye mixture with an old washcloth, and allow to dry. Apply another coat until the spots have blended into the background. Allows you to minimally sand the the stocks, keep all your contours and save your proofmarks. Trust me. This will work like a charm! Follow it up with BLO cut with 10 percent Linspeed oil and you will be well pleased with your result.

Attachment 27892i have blue tank set up to hot tank stocks, i add a cup of Brownells 909 cleaner, let heat up to a nice temp, and put the stocks in for about 15 mins, then remove, wrinse and let dry in a shaded area.
repeat if needed, never leave the wood in for longer then 20 mins, as warping will happen, on that note, if you have a warped stock or handguard, leave it in for 30 mins, then clamp it onto a straight board. then let dry.
works like a champ.

FWIW, if you DO get iron stains in wood, brush on a mild solution of nitric acid. The stains instantly disappear. Immediately neutralize it with baking soda solution, applied twice, then thoroughly rinse with warm water and let dry completely
