How to do it

Time

Water
Lukewarm, 30–40 °C

Take the strap off the watch. Lukewarm water and one drop of mild soap.

With these answers we do not recommend the ultrasonic cleaner, so there is no how-to.

Pick your cleaner to see if it fits, which setting to use and what its manual says.

Why

Rubber and silicone withstand water and mild soap – Apple recommends soap and water for its sport bands. Ultrasound removes dirt from the texture and the buckle. Heat can affect the material, so keep it lukewarm.

Watch out for

  • Never with the watch or smartwatch attached
  • Leather-lined hybrid straps: avoid
