That was me. It was "Cutex" brand, with acetone, and it had been the customer's diiscovery! I was unable to find the acetone-containing Cutex nail polish remover locally, but did find acetone-free Cutex which worked just as well, on another piano. It may be that it only works on certain specific early plastics 0 types of celuloid. There is a certain "technique" to using it, I found. You have to be fast, and use a fresh surface or kitchen (paper) towel, or tissue, every key or two. Best regards, David. List Some time ago, someone on the list experimented with a nail polish remover on yellowed- plastic keytops with very good success. Could someone refresh my memory what brand of nail polish remover was used and the ingredients? Tom Servinsky -------------- next part -------------- An HTML attachment was scrubbed...
