Works very well for that waxy dingy buildup on some plastic keys, but equally good for ivory. Some sharps bleed black dye onto the rag, though. I have had a customer who rubbed down a very dirty old rosewood upright with the finest grade of automotive rubbing compound, followed by furniture wax, and the results were stunning. For very rough and dirty and crazed old finishes, I sometimes wet some 0000 steel wool with Old English, wipe it on a small place at a time, then scrub with it (more gently if the finish isn't too bad), followed by wiping it off and waxing. The color improves, the roughness smooths out, scratches usually disappear, and with care those paint flecks which these pianos so often seem to have, lift off before the varnish does. White rings darken, but usually leave bare wood if they weren't superficial. Really cheap finishes get big "mud" buildups where hands rest, like the cheeks and keyslip, and if you scrub those with steel wool and polish, the whole finish disappears. The "mud" seems to be incorporated into the cheap finish. I haven't used toothpaste on the varnish, but on a damp rag it might work. It's just a mild and nontoxic abrasive, complete with a pleasant mint aroma. If used on a dry rag, I would think it would just make a smeary mess. Too damp and you might leave white marks. I prefer oily stuff like furniture polish or Old English on varnish, though polyester or lacquered finishes on grands I often wipe down with a barely damp rag. Pianos in institutions are often filthy dirty, and the people using them really like having them cleaned up. Susan </html>
