[pianotech] cleaning key tops

[Terry Farrell]

Acetone is a common ingredient in lacquer thinner, which is a blend of  
several organic solvents. Acetone is generally less aggressive than  
lacquer thinner. Other than that, yes they are similar. I think you  
are probably correct that acetone will eat a plastic keytop - but  
perhaps more slowly than lacquer thinner. I meant by different beast  
that it was not the same thing.
