A very stiff bristle brush works well. I usually ruin one per bridge, but it does scour the pins and bridge surface. Also, I don't think it is overkill to replace the bridge pins if they are corroded at the contact point. This is particularly true on the top two or three octaves. It is usual to see a bridge that needs re-notching once the pins are out, and it does make a noticible difference in the sound. Regards, Ed Foote
