Proper flute maintenance is essential for ensuring its longevity and optimal performance. Regularly clean the exterior with a soft cloth to remove fingerprints and moisture. Use a cleaning rod with a cloth to gently clean the inside of the flute after each use, preventing buildup of dirt and debris. Additionally, check the pads and keys for any signs of wear or damage. If you notice any issues, consult a professional flute technician for repairs. Regular maintenance not only enhances sound quality but also helps avoid costly repairs in the future.
