During workout: The Sensor comes with a removable plug for the charging port, please use this plug in the port whilst working out so sweat does not get into the device.

Sensor: Remove the Prevayl Sensor from the chest strap after every use and dry it with a soft cloth or towel, this will prevent long-term sweat damage.
Do not charge it straight away let it dry before charging

Strap: Rinse the chest strap under running water after every use and hang to dry. If necessary, wash at 30°C without a comforter. *DO NOT IRON, DRY CLEAN OR BLEACH THE CHEST STRAP.
