Use a toothpick or a toothbrush with rubbing alcohol.
Make sure not to scrape the contacts with a wire brush or anything metal, since this can damage the plating and cause corrosion.

If you use a toothbrush, dry with a cloth or tissue before charging.

Clean the pins on your charging cable. To do so:
Soak a cotton swab with alcohol and press the swab to the pins carefully.
Make sure that no debris from the swab is left behind.

Clean the removable pebble if you have a Flex series tracker. To do so:
Take the pebble out the wristband and clean it with a cotton swab and rubbing alcohol.
