Thank you for your review and for your feedback. We are sorry to hear about your experience. At the press of a button our Enfinigy Milk Frother will heat and froth your milk or milk substitutes or whip up creamy hot or cold cocoa drinks with our easy to clean, removable whisks. We recommend shortly, after using your Frother rinse the whisks well with warm water before the milk residue dries, then wash them with dish soap and a cloth or sponge and warm water. Dry the whisks thoroughly with a clean cloth. We hope this helps!
