Then you will need an agraffe removal tool V268
When removing the agraffes there will be underneath the agraffe thin spacer washers you need to count them for each note as they will need to be put back, some get stuck to the frame its best to put them on a wire for each note, as some can be stuck together. You may have to buy some new washers as well as the new agraffe may not match.
once you have removed the agraffes you may be able to clean them on a buffing wheel and use a pipe cleaner to clean out the holes. To clean them on a buffing wheel you need to make a gig to hold them. This is a piece of hardwood dowel with a hole drilled in the end smaller than the agraffe thread, you screw them into the dowel
