To clean your Ivy, use a damp cloth and wipe down the device and metal parts. For the back of the device around the pins, we recommend using a small brush or a clean dry cloth that will remove the residue between the pins and housing. This part is especially important as too much buildup can cause problems with charging.
The silicone bracelet is best cleaned by using cold water and detergent-free soap and then wiping the bracelet down with a dry cloth.
You should consider cleaning your Ivy once a month to ensure it continues to work properly and to the best of its abilities.
