Learn how to clean the steam wand on the Rancilio Silvia.
Steam Wand Cleaning
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.
