After making your wonderful cappuccino you need to clean up the machine. Most of us may have some trouble with removing the film of fat from the Steam Wand. The Black Frothing Sleeve can be washed with warm water and soap but the Steam Wand is more of a challenge. I found out that after using some paper towel socked in warm water I can completely remove the film by using some vinegar diluted with water. Just for those who did not know..... happy cappuccino! AP
