How do I clean the Steam Wand after frothing milk?

After every use, immediately purge the Steam Wand by turning the dial to HOT WATER for 1-2 seconds, then wipe the Steam Wand with a damp cloth to remove milk residue. Every 2-3 months, soak the Steam Wand overnight in the milk pitcher with warm water and one Espresso Machine Cleaning Tablet, rinse thoroughly in the morning, and run hot water through it for 40 seconds.
