How often to clean coffee maker
You should clean your coffee maker every 2-4 months, depending on how regularly you use it. However, that doesn’t mean you should ignore it the rest of the time. Mold likes darkness and humidity, so one of the best ways to avoid mold growth is to open the lid of your coffee maker when it’s not in use. This helps the water inside to evaporate and lets light reach the insides where mold likes to grow.
If you notice your coffee tastes bitter, or the coffee maker has a strong odor when in use, it’s time for a cleaning, even if it hasn’t been very long since it was last done. There are many variables that can affect coffee makers, from water hardness to the type of bean you use, so look for signs your coffee maker is getting dirty. A buildup of mineral deposits (also known as limescale) can affect the performance of your coffee maker and ultimately reduce its lifespan.
