I found a witch's brew in a North Carolina antique shop that I use often. It's called "Kramer's Best Antique Improver" and it is found at www.kramerize.com
. The phone number is (816)252-9512. It's in wide use among the antique dealers in Western N. Carolina.
Also, if you are not familiar with "Liberon" products and particurly, their 0000 steel wool, then do yourself a favor and round some up. The steel wool is close to the abrasiveness of a new baby diaper. The wax's they make are equally nice to work with.
Hope this is of some benefit to you. Let us know haw you come out.
