Algae grow fast when exposed to sunlight, for instance, when your Moccamaster is placed near a window. Moccamaster recommends treating an algae contamination with Clean Drop. To use Clean Drop, fill half of the water container with hot (not boiling!) water and add a sachet of Clean Drop. Wait one hour, then pour out the water used for cleaning, any chunks of algae still left in the container can be cleaned with a paper or cloth towel. ,Rinse the container with clean water at least twice, before turning the machine on for a water-only cycle.

Cleaning the spare parts

Although we mention that the glass jug and thermos carafe are not dishwasher safe, the remaining parts (lid, filter container) can be cleaned in a dishwasher.

Cleaning the machine

To clean your Moccamaster we recommend using Clean Drop. You can order Clean Drop from the Moccamaster webshop.We do not recommend filling up the water reservoir with the coffee jug, because contamination from a dirty jug might affect longevity of the machine.

Cleaning a glas jug

We recommend removing the lid from the jug as little as possible, as excessive use reduces the lifetime of plastic stubs. Moccamaster also warns not to clean the glass jug in a dishwasher.

To fill the water container of the Moccamaster, please use a separate, clean bottle or carafe with water.

Cleaning a thermos jug

To maintain an excellent coffee taste, it is important to regularly clean the jug.

Put a dishwasher tablet, or dishwashing liquid in the jug, fill it with hot or cooking water, stir with a wooden spoon then let it sit for an hour.
After cleaning, empty the jug, clean with a brush, and rinse at least two times with water, before using the jug again.


Descaling any household appliance that uses water is important as it increases the longevity and quality of your Moccamaster. We recommend using Durgol descaler after every 100 brew cycles (every pack of filter papers) or when the glass tube inside the reservoir becomes cloudy.

We do not recommend using vinegar or citric acid to descale as they might damage the machine, leave an unpleasant taste, or cause issues with your Moccamasters’ mechanical parts.

NOTE: Please refrain from using descalers with high citric acid content, such as a biodegradable descaler.

The citric acid can cause a chemical reaction with the copper of our heating element, resulting in a persistent bad taste.

If you have already used a high-acid descaler, please clean the machine several times with a soda solution, as this will neutralize the effect of the citric acid, and rinse several times with water.
