An apparatus may include a first support, a first cleaning material coupled to a first side of the first support, a second support rotatably coupled to the first support at a first edge of the second support, the second support defining a first opening disposed adjacent to a second edge of the second support opposite the first edge, a second cleaning material coupled to a first side of the second support, and a latch coupled to the first support, the latch to engage the first opening of the second support to maintain the first side of the first support in a substantially fixed relationship with respect to the first side of the second support.Some aspects include placing a second support between a musical instrument and a string coupled to the musical instrument, the second support defining a first opening disposed adjacent to a first edge of the second support, rotating a first support with respect to the second support to dispose the string between the first support and the second support, the first support coupled to a second edge of the second support opposite the first edge, and engaging a latch coupled to the first support with the first opening of the second support to maintain the first support in a substantially fixed relationship with respect to the second support.
