Working on yet another cellarette, this one with a fair amount of maple stringing. I saw a comment that potassium dichromate can be used on mahogany without affecting the color of the stringing. Since the reaction is with the tannic acid, and maple has little, I suspect this is true.
Before trying this, does anyone have any experience with this approach?
And, yes, I am acquainted with the hazards of hexavalent chromium. I recall removing some especially stubborn something from lab glassware back in organic chem 2, using a solution of 98% sulfuric acid and potassium dichromate. It worked, but was scary to use.
