Without knowing which Formby product you used, I'm at a disadvantage, but your desciption sounds like the result of using a product called "Refinisher" which is also made by a number of other companies. It is a very strong solvent and, on antiques, it is a stripper. If you want to clean the 'crap' off old furniture and still retain the patina, there is only one product to use ....Wood Elixir. I'm not saying that because I make it, I'm saying that because it is true. The answer now is to treat the remaining pieces with Wood Elixir to gain the results you wish and then replicate that result on the 'over done' piece. That part can't be done with Wood Elixir alone, but when you're ready and upon your request, I'll tell you how to do it. (It's a longer process but you can do it) --Previous Message-- : My husband used a Formby product on an antique : chair which is part of a set of 4 with a : drop leaf table. I had expressed the : desire to "clean up" the set : & rewax it, as it (especially the : table legs)are nearly black with grime : & build up over years. I wanted to do : this without removing the patina. My : husband found a product which claimed to : do this & used it on one chair. Oops! : The product removed dirt, grime, old wax, : some of the finish, & nearly all of : that beautiful old patina that makes : antiques so valuable. Now we know what : NOT to do on the rest of the chairs & : table, but is there anything to be done : with the first chair on which he already : worked. The original stain was removed on : some of the chair edges & revealed : scratches on the chair legs. :
