The BG Alto Saxophone Body Swab is a must-have for musicians who want to lengthen the lifespan of their saxophone. This grey microfiber cloth gently cleans the inside of your saxophone’s body without scratching it. Simply feed the attached string through the body and pull the swab out the other side. Due to the metal weight inside of the swab, pulling the swab through the body is quick and easy. Saxophonists at Sweetwater love how well this long-lasting, high-absorption cloth cleans their instrument.
