My French polishing goes well for a while then the muneca seems to start leaving particles in the finish. Can you tell me what is wrong?
Three things could be happening. First, you may be using the muneca too wet. This will have a tendency to remove shellac and leave minute particles and fibers from the muneca in the finish. Be sure to wring the muneca often and use the blot test. Second, you may be using too little oil. Not enough oil will cause the muneca to stick which will also leave particles of muneca fibers in the finish. Use a bit more oil and see if this solves the problem. The oil can always be removed during the stiffing. Third, your muneca may be contaminated with particles either from worn and loose fibers on the muneca or from particles in the air that have landed on the guitar. Always make a practice of cleaning the guitar and the perimeter of the muneca before each session. You also may want to change the muneca cover when it looks worn or is glazing over. Q: Sometimes my muneca stops feeding out the shellac and I can’t seem to get the cloud of shellac back. Wringing out the muneca doesn’t seem to help.
