Steam Wand Cleaning
Cleaning and wiping down the steam wand on your Expobar Brewtus IV is something you should do at least once a day when you're finished frothing milk to prevent the buildup of burnt on milk. The video below shows how to properly clean a commercial steam wand on a semi-automatic espresso machine.
After each use, the steam wand should be wiped down, and then purged by running a few short bursts of steam. Make sure that there is no milk left on the wand. The steam wand should be cleaned daily once the machine is finished for the day. Milk residues quickly build up on the steam wand, so it's important to keep it clean to prevent blockages from forming.
