Thank You for the responses,
I went out last night, while chasing down parts for other stuff, found and bought a couple of 12oz cans of Bar Keepers Friend. I'm going to give that a go. Although the Bar Keepers Friend in 12oz form was cheap enough. I would like to find oxalic acid in a larger package, say 1-5 lbs. but not having much luck finding a local source. I'll seach out ZUD, and see what I can find
Gas, Diesel fuel, acetone, mineral spirits, Goo Gone, Bleach, etc., I have used them on other stuff, with good results. but I really did'nt think they would be effective in this circumstance.
So far as muratic acid, I"d just soon only use that as a last resort, even with gloves, resporator and goggles its pretty nasty stuff to work with.
Thanks again, to everyone that responded. Anyone know of a source for Oxalic acid in bigger bulk form, please share. I have other stuff to clean up in the future.
