In order to maintain your Roll Uh Bowl, we recommend cleaning after each use. You are welcome to use warm soapy water on the silicone tube and alcohol or a standard bowl cleaner on the eject-a-bowl and downstem. Do not use boiling water, as this can cause damage to the product. Do not use alcohol or alcohol-based cleaners on the silicone tube, as that can break down the silicone. The Roll Uh Bowl is dishwasher safe, so feel free to use that method as well! Check out this video on how to clean the Roll Uh Bowl.
