In this case I would probably use one or two drops of keytop/acetone solution fairly dilute (like thin non-fat milk color). One keytop to 8 - 10 oz's of acetone depending on the thickness of the key top. Dispense it from a fine tipped hypo oiler in the smallest quantity you can. Mix in a separate jar and put only about 1/16" of liquid into a 2oz hypo oiler which will allow you to control the flow rate much more easily (Pianotek sells them). Let dry 15 minutes and bang the hammer on the string a few times to break up the crust. Don't saturate the hammer, all you want is a little edge at the strike point.

So now I am looking at hammer hardner, I hate to use the acetone on only two, and I never used it before (never ran into this peroblem before) What about the Schaff FORD hammer hardner. Is it any good? How about the brite tone? I bet the Brite tone is acetone. BTW Where does one obtain acetone. My first mind's idea is to buy a bottle as nail polish remover.
