How to Descale a Keurig Brewer

Your Keurig coffee brewer will benefit from regular maintenance. The scale buildup that occurs with use can cause the brewer to operate at below optimal temperature and can affect taste. Descaling every three to six months ensures your coffee will always be perfect and your Keurig will give years of service. Note: Descaling is always carried out without using a K-Cup.
