What you’ll learn: how to tell which surface your instrument has (stainless, nitrided, or coated steel) because each needs different care, why moisture — not time — is what actually causes rust, why every handpan benefits from oil and how often to apply it (every 10 days for the Arsha range and the Tapadum 9 Notes, every 15 to 20 days for premium stainless models), which oils are genuinely safe on steel you hold against your body, why a coated tongue drum should not be treated the same way, how to store and travel safely, and what to do if you find rust.
