6. Care and Maintenance
Proper care will extend the life and appearance of your silicone bands.
- Cleaning: Regularly clean your band with mild soap and water. Rinse thoroughly and dry with a soft, lint-free cloth.
- Avoid Harsh Chemicals: Do not expose the band to strong chemicals, solvents, or abrasive cleaners, as these can damage the silicone material.
- Storage: When not in use, store the band in a cool, dry place away from direct sunlight to prevent discoloration or degradation.
- Sweat and Water: The bands are resistant to sweat and water. After intense workouts or exposure to water, it is recommended to clean and dry the band to prevent skin irritation and maintain hygiene.
