Your sport ID can be rinsed.
Occasionally you can wash your Daredevil ID in the machine. Make sure to remove the stainless steel plate and buckle so that they do not get scratched in the machine. Correctly put the Velcro band back in place before washing.
It is better not to wash it together with your linen. The Velcro might cling to it and damage it.
We recommend a gentle wash at a low temperature.
