If you prepare milk drinks regularly, the milk system should be rinsed after every use and cleaned thoroughly according to your manufacturer's recommendations. Machines making several milk drinks each day will generally require more frequent deep cleaning than those used occasionally.

Poor milk froth is often caused by dried milk residue blocking the milk circuit, frothing nozzle or air inlet. Cleaning the milk system thoroughly is usually the first step before investigating more serious faults.

Automatic rinsing helps remove fresh milk, but it doesn't always remove dried milk proteins and fats. Regular deep cleaning with a suitable milk system cleaner helps keep the milk circuit hygienic and performing properly.

Milk naturally contains proteins and fats that dry quickly inside pipes and frothing components. If the system isn't cleaned soon after use, these deposits gradually build up and restrict milk flow.

Common signs include weaker milk foam, slower milk flow, spluttering during dispensing, inconsistent frothing, unusual noises while frothing and visible milk residue around the frother or milk connectors. Cleaning the system promptly can often restore normal performance before a blockage develops.
