Damper Lever Felt Excavation

[pmc033 at earthlink.net]

I've seen this many times.  If you get a wet strip of cloth, you can "shoe-shine"  the spoons clean again.  Usually, you have to replace the felt.  I think that some moisture gets in there and affects the felt.  Something in the felt then gets on the spoons and dries, making it like sandpaper.  
The symptom is opposite to what you find when there is excess friction in the action- the keys are more sluggish when you play the note "without" using the damper pedal.

Yup, that's what I used - action cloth. And I agree with you that the felt likely played a role in forming the gritty coating on the spoon. I don't have a clue as to how that might work - but the gritty coating was red.....

I had a customer piano with the same trouble exactly. As I recall, the felt was part of the problem and yours looks suspicious, too. I replaced it with a good woven action cloth.
