Are you dealing with rust issues? This Miracle Cloth will help.

Use the Miracle Cloth with caution on rust spots only (be aware it may slightly discolor your Halo) then place it back in its sealed bag. Once your Halo is free of rust, apply a coat of handpan oil using a clean cloth and let it air dry (repeat every 2-3 months for indoor playing or 2-3 weeks for outdoor playing).
