According to a recent NSF international report coffee machines are the five most germiest in the world containing 50% of the tested reservoir containing yeast or mould. The bacteria can cause an allergic response and infection, which is why your coffee maker can cause serious damage.
Plan to clean electric coffee pot once a month if you use it every day. Only once every three to six months could be necessary for occasional coffee consumers. However, you should clean your coffee maker if you see obvious accumulation around the pot or basket or if your coffee tastes strange. Make sure to have no coffee residue before beginning the cleaning process.
