Marshall If the keytops are plastic. do NOT use nail polish remover. Nail polish remover is lacquer thinner, which eats up plastic. Unfortunately, there is nothing this customer can do to remove the magic marker. One of the ingredients in the ink is lacquer, The black ink has basically melted into the keytop material. While some of it can be removed with naphtha, there will always be a black residue inthe keytop. If the keytops are ivory you can use alcohol and/or lacquer thinner to remove the stain. But the longer you wait, the more that stuff will seep into the grain of the ivory, and it will be very difficult to remove the stain.

So what could be used to remove permanent marker without damaging a key top. I do not know if they are ivor or plastic. It's a Pratt & Read grand according to her.
