Due to regular use, the French press filter eventually becomes covered with a film, which is “supplemented” by particles of tea leaves or ground coffee grounds.
In this case, regular detergent is not very effective.
Instead, try a quick and easy method that requires a minimum of ingredients.
So, to return the product to its original state, you will need to put a kettle on the stove to boil water.
While you wait for the water to boil, pour 3 tablespoons of citric acid into the French press.
Now fill the container with boiling water and set aside for 1.5-2 hours.
After the specified time, drain the water and clean the piston with filters with an unnecessary toothbrush - even old plaque will go away without much effort.
Thus, the process of active cleaning will actually take a few minutes, and the result will be truly impressive.
