De-Scaling Your Brewer - Keurig B31 Owner's Manual

De-Scaling Your Brewer

Depending on the mineral content of the water, calcium deposits or scale
may build up in your Brewer. Scale is non-toxic but left unattended, it can
hinder Brewer performance. De-scaling your Brewer helps maintain the
heating element and other internal parts of the Brewer.
The Brewer should be de-scaled every 3-6 months to ensure optimal
performance or when there are white deposits in the Cold Water Reservoir.
It is possible for calcium deposits to build up faster, making it necessary to
de-scale more often.
