Care and cleaning
Regular cleaning supports comfort and reliable skin contact. Final material-specific instructions will be published with production hardware.

Use gentle cleaning
Use a soft cloth and the cleaning method approved in the production care guide. Avoid abrasive pads, sharp tools and unapproved solvents.
Keep the sensor window clear
Lotion, sunscreen, soap residue and dirt can reduce consistent optical contact. Clean residue from the underside without scratching it.
Let straps dry fully
A damp woven strap can hold moisture against the skin. Allow it to dry before wearing for long periods.
Inspect the hardware
If a strap, buckle, dock or housing is damaged, stop using the affected part until ARC Support confirms it is safe to continue.
Do not guess at chemical compatibility
Material compatibility depends on the final production finish and strap. Follow the published care guide rather than using harsh disinfectants by default.
