@TonyRV2-Thanks!
@thunter9- I'm not sure how much oxalic acid is in it, but it is a large percentage. Kinda like the difference between Neatsfoot Oil, and Neatsfoot Compound. Oxalic Acid is also used by Beekeepers, for cleaning out parasites from the hives. And, honey that the bees make, is used in making Mead, a sort of ancient beer/wine beverage, which is not served by barkeepers. How's that for the circle of life?
