On all alkalizers, there is a tendency for mineral or scale deposits to accumulate. This is nothing to be worried about but will result in a reduction in performance with regard to alkalizing ability.

To perform the cleanse:

1. Remove the minerals cup from the AlkaPod
2. Place into a glass and fill with white vinegar
3. To extend the life of your filter, soak in white vinegar for 5 minutes every 3 months
4. Dry in sunlight

Any white vinegar is OK for this task.
