Why cleaning your milk system is more important than you think
Milk at temperatures above 20°C begins to ferment within 2–4 hours. The capillaries, tubes, and frothing chamber of a coffee machine operate at much higher temperatures—milk residues left behind after each use quickly form a biofilm. Biofilm is a layer of bacteria that adheres to the system walls and cannot be removed by water flow alone.
Effects of neglect: a sour or bitter aftertaste in cappuccino, foam that collapses quickly, a machine that froths milk less effectively, and in extreme cases—clogged capillaries and costly repairs. Vitaclean Milk System Cleaner (Vitaclean milk system fluid) chemically breaks down milk fat, proteins, and biofilm—in one cycle, without needing to disassemble the coffee machine.
Symptoms of a dirty milk system
| Symptom | What it means |
|---|---|
| Sour or musty smell from the nozzle | Milk protein fermentation - biofilm in the capillaries |
| Foam collapses quickly after making cappuccino | Milk fat or detergent residues are breaking down the foam structure |
| Machine froths less than it used to | Narrowed capillaries or clogged nozzle - reduced airflow |
| Bitter aftertaste in milk-based coffee | Old protein deposits in the system add an undesirable flavor to the coffee mix |
| White or brown marks in the milk container | Calcium-protein deposits - require a deep cleaning |
Daily routine vs. deep cleaning
| Cleaning type | When | Vitaclean amount | Time |
|---|---|---|---|
| Quick rinse | After each milk use | 50 ml solution (5 ml + 45 ml water) | 2–3 min |
| Weekly cleaning | Once a week | 100 ml solution (10 ml + 90 ml water) | 5–10 min |
| Deep cleaning | Every 2–4 weeks or if there is a strong odor | Soaking nozzles - 50 ml + 200 ml water, 15 min | 15–20 min |
Cleaning step-by-step
Automatic milk system (DeLonghi LatteCrema, Jura, Siemens):
- Pour 100 ml of solution (10 ml Vitaclean + 90 ml warm water) into the milk container.
- Start the milk system cleaning program (machine menu).
- The machine automatically pushes the solution through the system - cycle takes 5–8 min.
- Fill the container with clean water and run the rinsing program.
Manual nozzle and tube (cappuccinatore):
- Soak the nozzle in a solution of 50 ml Vitaclean + 200 ml warm water for 5–10 minutes.
- Run the solution through the nozzle several times (tube submerged in a cup with the solution + steam).
- Rinse with clean water - at least 2 times.
Milk container and tubes:
- Disassemble the container into its component parts.
- Soak in a solution of 50 ml Vitaclean + 500 ml water for 10–15 minutes.
- Rinse each part separately. Leave to dry with the lid open.
What to use for cleaning and what to avoid
| Agent | Effectiveness | Safety |
|---|---|---|
| Hot water alone | removes fresh residue | ✓ safe, but does not remove biofilm |
| Dish soap | moderate | ❌ surfactant residues break down foam |
| Vinegar or citric acid | good for limescale, weak on fat | ⚠️ damages seals and metal nozzles |
| Vitaclean for milk system | very good - fat + biofilm | ✓ safe for seals and nozzles |
How often to clean to prevent odors from returning
The most common mistake is cleaning only when an odor appears. By then, the biofilm is already thick and requires intensive cleaning. Simple rule: after each use = quick rinse, once a week = full cycle.
Additional tips: never leave milk in the container overnight, store the container in the fridge after each use, or leave it completely empty with the lid open. On warm days (above 25°C), shorten the cleaning interval to every 3–4 days.

How often should I clean the milk system in my coffee machine?
After each use - a quick rinse with 50 ml of solution. Once a week - a full 100 ml cycle. Milk ferments in the capillaries in as little as 2–4 hours at room temperature.
What should I use to clean the milk frothing nozzle?
Soak the nozzle in Vitaclean solution (50 ml + 200 ml warm water) for 5–10 minutes. For stubborn deposits, use a soft nozzle brush. Do not use a wire sponge - it will scratch the surface.
Why does milk in the machine's system go sour?
Milk residues ferment in the capillaries and frothing chamber within 2–4 hours. Biofilm forms on the walls - water flow alone does not remove it. You need a cleaning agent that breaks down milk fat and proteins.
Is Vitaclean safe for seals and nozzles?
Yes. It has a pH-neutral formula, safe for silicone seals, plastic tubes, and metal cappuccino nozzles. It contains no aggressive acids or bases.
How do I clean an automatic milk container (e.g., DeLonghi LatteCrema)?
Remove and disassemble the container. Soak parts in Vitaclean solution (50 ml + 500 ml water) for 10–15 minutes. Rinse and leave to dry with the lid open. Do not wash in the dishwasher - high temperatures deform the seals.
Why does milk foam collapse quickly?
Milk fat or detergent residues in the nozzle break down the foam structure. Clean thoroughly with Vitaclean and rinse 2–3 times with clean water - you will see results after the first full cycle.
Can the milk system be cleaned with only hot water?
Hot water removes fresh milk residues, but it does not break down biofilm or calcified protein deposits. After 1–2 weeks of rinsing with water alone, blockages form in the capillaries that water can no longer remove.
