I stored a bunch of lovely mahogany stock milled as fiddle rail stock in my loft, against the day I would need it for Ceol Mor - which day has come. But I clearly didn't pay enough attention, as the location I chose was right below some kind of spider paradise, and my stock is heavily, um, speckled in many places with spider crap. (OK, OK, I'll accept an LOL pause here...) Looks like it may stain in much the way that bird crap does. Before I scrape, sand, or assault with solvents, anyone have any suggestions in how to remove the stains???????????
