Rubber straps handle sweat and water better than leather, but they still collect sunscreen, salt, soap, and skin oil. Regular cleaning keeps them comfortable and prevents odor.
Remove the strap if possible
Taking the strap off protects the watch case and makes the underside easier to clean. If it stays attached, confirm the watch can safely handle water and keep the crown closed.
Use mild soap
- Rinse with lukewarm water.
- Add a small amount of mild dish soap.
- Scrub both sides with a soft toothbrush.
- Clean around the buckle, keepers, and spring-bar ends.
- Rinse until no soap remains.
- Pat dry and let it air-dry completely.
Avoid bleach, solvents, alcohol, acetone, abrasive powder, and very hot water. They can dry, discolor, or weaken rubber and silicone.
Odor, sunscreen, and salt
Clean the underside after workouts. Rinse after swimming or heavy sunscreen use. If odor returns immediately, check the holes, keeper loops, and spring-bar channels for trapped buildup.
When to replace it
Replace a strap that shows cracks, tearing around the holes, a split keeper, or damage near the spring bars. Cleaning cannot restore weakened material.
