Marcus Bonna Fishscale Microfiber Cloth

Marcus Bonna advises placing the cloth on top of your instrument inside the case, where your hands usually rest on the instrument. Removes stains and oils deposited by players' hands that may damage the instrument if they accumulate inside the case. Soft, with high water absorption, and anti-bacterial. Does not scratch the instrument surface.  The cloth can be reused many times. It should be washed by hand with neutral soup. Don't wash it in the washing machine and don't use any kind of bleach. Let it dry in the shade. Microfiber cloth, 80% polyester and 20% polyamide.
