Milk systems don’t clean themselves. And when they’re neglected, the impact is immediate—poor taste, blocked lines, and unnecessary service issues.
Rinza4 is built to solve that. A simple, structured cleaning solution designed specifically for bean-to-cup and superautomatic coffee machines.
What is Rinza4?
Rinza4 is a 4-week milk system cleaning kit, with each box containing pre-measured weekly doses to guide consistent cleaning routines.
-
24 x 10g Alkaline sachets
-
4 x 10g Acid sachets
-
Clearly labelled Weeks 1–4 schedule
No measuring. No confusion. Just a clear process that keeps machines clean and performing as they should.
Why Milk System Cleaning Matters
Milk residue builds up quickly inside:
-
Milk lines
-
Steam wands
-
Automatic frothing systems
Left untreated, this leads to:
-
Blockages and inconsistent milk flow
-
Bacterial build-up
-
Poor-tasting coffee
-
Increased maintenance and downtime
A consistent cleaning routine isn’t optional—it’s essential.
How Rinza4 Works
Rinza4 follows a simple weekly cycle that combines acid and alkaline cleaning for a more complete result:
-
Day 1: Acid clean
-
Days 2–7: Alkaline cleaning
-
Repeat weekly for 4 weeks
This combination helps:
-
Break down milk fats and proteins (alkaline)
-
Remove mineral deposits and scale (acid)
The result is a deeper, more effective clean across the entire milk system.
