Exclusive proprietary formulation as used by museums (e.g. The Vatican, British Museum, Louvre) to remove old wax, grime, etc. and unclog wood pores to allow the wood to "breathe" again. Will not dissolve shellac or varnish but will remove organic waxes and accumulated dirt. (Waxes and other organic materials can form acidic residues that break down wood structure over time.) This special pH neutral formulation of cleaners will not raise the grain or dehydrate the wood, and is safe for keywork.
