Your cup must be disinfected before storing each month. Rinse your cup, and boil in a pan or pot of water for 3 minutes. If you do not want to use a pot for disinfecting, you can use our Ruby Clean for boiling in the microwave or oven.  

After boiling, wait until your cup is cool, dry thoroughly and store in the organic cotton bag that came with your Ruby Cup.

When boiling your Ruby Cup, make sure you don’t over boil it (no more than 15 minutes), otherwise, the silicone will lose some of its bounciness and not open up so easily anymore when inserted, hence leading to potential troubles with leaking.
