Loose Tuning Pins
By Bruce Clark

As a retired tuner and player technician, I can say that any piano that I ever tuned which had been treated with a pin tightening agent, made the pianos very difficult to tune due to a certain amount of sponginess that the chemical created in the pin block. It was sort of like tuning a piano with pins set in bubble gum. It made the pins difficult to "set". The familiar "jump" in a tuning pin, that only piano tuners are aware of, is gone.

I have seen pianos that may have had the chemical applied in a sloppy way, causing corrosion and destruction on the coils wound around the tuning pin, and even corroded tuning pins.

This pin "dope" may have been an earlier version, but I saw so much damage from it, over the last 40 years, I never considered using it. Modern versions may be different, but if I had a valuable piano, I would not want any chemical used on it.
