Milkfrother brown cake removal without damaging the anti-stick coating

The first period an anti-stick coating works as you may expect. You allow to frother to dry after use and blow out the loose milk film from the bottom. One or two years later, when the anti-stick coating starts aging you will need to scratch the cake from the bottom. Even a 24 hour soak with water does not help. This video shows the solution to this problem. The method is applicable for all brands and models types of milkfrothers.
