To clean your Disney MagicBand or MagicBand+, use a soft, lint-free cloth slightly dampened with water and a mild soap. Since the bands are made of high-quality TPU (thermoplastic polyurethane) and are designed to be waterproof for swimming and rain, they are quite durable. For stubborn grime or sunscreen buildup, you can use a soft-bristled toothbrush to gently scrub the textured areas. Avoid using harsh chemicals, bleach, or abrasive cleaners, as these can degrade the material or damage the decorative "skin" and puck electronics. If you have a MagicBand+, be careful not to submerge it for extended periods while charging, and ensure the charging contacts on the back are dry and free of debris before plugging it in to maintain the longevity of the rechargeable internal battery.
