Clean Machine Milk Steamer Solution does a professional job of cleaning stubborn milk scum and build up from milk lines, valves and milk jugs.
To use, mix 50 ml of solution to 1/2 litre of water.
Auto Frothers: run the solution through the frothing device and repeat with fresh water twice. Soak all milk lines and frothing components once a week for up to 30 minutes and rinse thoroughly afterwards.
Steam Wands: steam solution in a milk jug as you would with your milk. Turn steam on & off over a one minute period allowing the solution to work its way up the steam arm. Repeat the process twice with fresh water.
