Clean the tube and reservoir regularly with brushes and warm soapy water. Periodic cleaning with the cleaning tabs keeps the reservoir and the tube free from a funky taste and odor. After washing the reservoir, dissolve one cleaning tab in there with up to 1 liter of warm water and let it rest for 5 minutes. Empty and rinse all components with fresh water. Refill or dry completely prior to storage on the drying hanger.
Avoid touching your eyes after handling the tablets. Do not swallow the tablet or drink water containing it.
