How to Clean Filter Coffee Machines

A filter coffee machine is the most commonly used type of coffee machine. And, according to many baristas, still one of the best ways to make delicious coffee. A coffee-making device such as this must be cleaned regularly to ensure that it does not clog due to limescale and to remove residual coffee oils that may have become rancid. The temperature of the water is very important when brewing coffee. If the heating element in the coffee machine is no longer able to release its heat properly due to limescale, the coffee will not taste as good.

How often does a coffee machine need to be cleaned?

With normal use, it is recommended to clean the coffee machine once a month. It is fairly easy to do. In addition, an inexpensive way to do this is with cleaning vinegar, or white vinegar.


  1. Empty the filter holder and first rinse it with water so that there is no coffee residue left on it.
  2. Put 1/3 cleaning vinegar in the coffee pot and add 2/3 water.
  3. Pour the vinegar mixture into the water reservoir of the machine and rinse the coffee pot with clean water.
  4. Place the empty coffee pot in the coffee machine and switch it on. The vinegar mixture will now go through the coffee machine and clean all the ducts inside the device.
  5. If the water tank is empty, empty the coffee pot and rinse it again.

Pour clean water into the water reservoir and put the coffee pot back in the machine. The ducts of the coffee machine will then now be rinsed with clean water. Repeat this step two more times and then taste the water to check if it tastes of vinegar. If this is the case, repeat the rinsing process as often as necessary until the water no longer tastes of vinegar.
