Does the silicone sleeve need to be removed with each washing?
We recommend that you clean the bottle and all components (including the silicone sleeve) separately after each use. All parts are dishwasher safe. We recommend top rack only. While the smaller parts such as the nipple and sealer disc do well in the dishwasher, they are small and easy to lose and we recommend hand washing. Please allow all the washed parts to dry completely before reassembling the bottle.
