The best way to clean your bottle is by removing the lid and taking off the bottom ring, then carefully remove the sensor stick. Please, do NOT put the sensor stick in the dishwasher as that may damage the sensor.
You can put the bottle lid and bottom ring in the dishwasher.
Simply hand wash the sensor tube in warm water. MAKE SURE THE SENSOR STICK'S BOTTOM LID IS SCREWED DOWN TIGHTLY TO ENSURE A WATER TIGHT SEAL.
Be sure to clean your bottle daily.
