The easiest way to clean your Incredibowl is using boiling water. Cleaning both the glass bowl and the Bowl Armor can be done by just dropping it into a pot of boiling water. Just make sure you do not put the expansion chamber in the boiling water because it can melt and/or warp. To clean the expansion chamber you can soak it in warm water and then scrub it. Also don’t make the mistake of putting the expansion chamber in the dishwasher either, that spells certain doom for your expansion chamber.
