An apparatus may include a first support, a first cleaning material coupled to a first side of the first support, a second support coupled to the first support at a first edge of the second support, a second cleaning material coupled to a first side of the second support, and a third cleaning material coupled to a second side of the second support. Some aspects include placement of a second support between a musical instrument and a string coupled to the musical instrument, and rotation of a first support coupled to a first edge of the second support with respect to the second support to dispose the string between the first support and the second support, to bring a first cleaning material coupled to a first side of the first support in contact with the string, to bring a second cleaning material coupled to a first side of the second support in contact with the string, and to bring a third cleaning material coupled to a second side of the second support in contact with the musical instrument. |
