How can I help the extraction of the bowl from its place after the preparation of ice cream?

Before preparing the ice cream we recommend to remove the bowl and dampen the aluminum bottom of the machine with a form of alcohol that would be used for consumption such as vodka or rum. Be careful not to pour it in the center (plastic).Then make sure to place a perfetly dried bowl inside the machine. In this way the extraction of the bowl will be easier and faster.
