Below is a step-by-step plan for the best way to clean the blue discs:
1. Dismantle the discs, as explained in the manual.
2. Then place them in a container with a mixture of cleaning vinegar and lukewarm water (1:10) or use a decalcifying tablet.
3. Leave it to soak and then carefully brush over it to loosen it.
4. Rinse and dry thoroughly so that no acidic odour is left behind.

We recommend doing this once a month.
