The Microfiber Swab keeps your baritone or euphonium clean and sanitary. Its ultra-absorbent fibers lift away built-up moisture and debris from the inside of your instrument. The swab's dense pile grabs onto particles that can build up and affect your instrument's tone and playability over time. Regular cleaning with the Microfiber Swab helps prevent corrosion and keeps slides and valves operating smoothly. After extended playing or storage, use the swab to restore your instrument to like-new condition. The swab's fibers gently clean without scratching delicate finishes. For the best care of your brass instrument, add the Microfiber Swab to your regular maintenance routine.
