The ingredients in BC Plum Brown on the label reads: Nitric acid, sodium nitrate and potassium chlorate. Hmmn, nitric acid, as in aqua fortis.
Took a tablespoon of Plum Brown, dissolved a bit of steel wool clippings in it to treat a piece of scrap maple. After applying heat, put some baking soda/water mix onto the wood, it foamed up pretty good when killing the treatment. I lightly sanded and rubbed in a little tung oil. Below is the result.
