I tried soaking on a BIG set of hammers that someone had soaked 
literally, clear through, with some unidentified hardener. They not 
only clanged like a pie plate banjo, but the 5+ grams of hardener in 
the bass hammers put the down weight well over 70g. I soaked, 
scrubbed, needled, pounded, and squeezed for most of a day and 
barely made a dent. They were like phenolic with a light surface 
fuzz. Should have just written them off and started over with new 
hammers. You will likely have better luck with the keytop, soaking 
and needling.
