I bought a SinuFlow ReadyRinse bottle. Do I need to disinfect the tube prior to the first time use – or only on subsequent uses?

Dear Brian,You can use the SinuFlo Ready Rinse straight out of the bottle. You do not need to disinfect the tube or any part of the device prior to the first use. For subsequent uses, please follow the directions for cleaning and disinfecting outlined in the brochure.
