Fitbit devices often come with customizable bands, and cleaning requirements change depending on the type of band you have.
For instance, if you’re wearing an elastomer band, clean the band and your wrist with water or a small amount of rubbing alcohol. Do not clean using a hand sanitizer, dish soap, body soap, hand soap, cleaning wipes, or household cleaner as these can get trapped between the band and skin and cause irritation.
Leather bands must be wiped down with a non-abrasive lint-free cloth, lightly dampened at most. Fitbit’s leather bands aren’t resistant to water, and cleaning with water might cause discoloration. Metal bands might also experience tarnish or discoloration if excessively cleaned with water.
