Here is a video on cleaning your bottle.
The best way to clean your bottle is by removing the lid and then immediately removing the sensor stick. Do NOT put the sensor stick in the dishwasher or submerge in water as that may damage the sensor.
You can put the bottle lid and bottle cavity in the dishwasher.
Simply hand wash the sensor tube with warm water. MAKE SURE THE SENSOR STICK LID IS SCREWED DOWN AS TIGHTLY AS POSSIBLE TO ENSURE A WATER TIGHT SEAL. There should be almost no gap between the sensor stick lid and the sensor stick.
Be sure to clean your bottle thoroughly if you put anything other than water in your bottle.
When the bottle and lid are clean, reattach the sensor tube with the rounded side facing the mouth piece and you’re good to go.
