Using the Bellucci D088 Latte Pro Induction Milk Frother is a piece of cake. First, pour your milk or other liquid into the stainless - steel container. You can choose from four functions: hot frothed milk, cold frothed milk, hot milk, or hot chocolate. Just press the corresponding button and let the frother do its job. It will stop automatically once the liquid reaches the perfect temperature. When it comes to cleaning, you can simply put the stainless - steel container in the dishwasher. As for maintenance, keep it in a dry place and avoid overfilling the container. Also, make sure to use it with a 120V power supply and don't operate it without any liquid inside.
