[CAUT] Polishing Agraffes

[Mccoy, Alan]

Are you polishing the agraffes in the piano fully strung or removing them? Also are you polishing just the outside surfaces?

Dear Group-

What polishing compound do you find works well when cleaning up agraffes?  I have some from a new Boston that were discolored after an HVAC pipe leaked into the piano, down the (mostly) bass strings, and into the agraffes.  I used Hagerty Heavy-Duty copper brass & metal polish, which initial tests showed to work a little better than Brasso.  The results are not acceptable--the discoloration is still there, and the brass did not get that high shine I've seen when polishing capstans.

I'll have to re-do these, and would like to do so only once.

Any help appreciated.
