Hey, Alan, The only thing I've done to a pinblock like that one that gave me satisfactory results was to brush the holes. Pianotek sells a brush for this purpose, but I think it's a little too large and the bristles are too stiff. I have used a .270/.30 caliber rifle cleaning brush, brass bristles. I can't say if it actually did anything or if it just made me feel better. I have also had good results from doing nothing. I think Wim makes a good point about the pin size. If this is a Delignit-like block, I think I would try 3/0. If it's a multi-lam, or Steinway/Bolduc type, I believe I would go with 4/0. FWIW. Regards, Ken Z.
