The internal maintenance of a baritone requires precise intervention to remove accumulated calcium carbonate and organic residue, which often occurs at a higher rate than in a standard euphonium. Over time, these deposits constrict the internal bore, altering the acoustics and increasing air resistance. At our workshop in Lowton, we utilize ultrasonic cleaning and chemical
