After use, wash the diaphragm carefully with soap and water. Dry gently with a soft clean cloth or let it air dry. Store Caya in its case when not in use. You can reuse your diaphragm for up to 2 years.

Each time you use Caya, examine it carefully to ensure that there are no pin-holes or thin spots and that the spring rim is fully enclosed by silicone rubber. You might also label your case with the first use date to ensure you replace it within 2 years.
