As there are only a few components in the French Press it’s easy to disassemble and wash.

The filter mechanism has layers. These can be opened up to remove coffee residue that may have become lodged within the mechanism.

Remove the borosilicate glass carafe from the chrome housing support.

Tap bottom of the carafe gently to loosen coffee grounds. If they stubbornly refuse to budge, a wooden spoon or plastic spatula (not metal) helps to remove those stuck.

If you have a compost bin – great!  Coffee grounds are great for compost or add to a worm farm. They  Otherwise put in bin.

Separate components, lid, plunger – filter screens and discs and rinse well all well. Use a soft cloth or nylon brush to remove coffee residue. A little soap can be used but make sure you rinse well after cleaning to remove all soap.

Baking soda can be used instead of soap or for hard to remove coffee grounds.

The manufacturer recommends towel drying metal items immediately.

Grounds shouldn’t be put down the sink or garbage disposal. Dispose of in the bin or ideally compost or add to your worm farm.

Coffee grounds and compost

Coffee grounds help to make quality compost by adding nitrogen to the composting materials. By the way coffee filters from a drip filter machine can be added to compost too.


Considered a ‘green material’ despite their brown appearance, they sit alongside grass clippings and food scraps as ‘green’.


But to have a healthy compost bin that creates the necessary heat to break down the waste there has to be balance. In fact a 1:4 ratio, ‘green’ to ‘brown’ materials like dry leaves and newspapers to make nutrient rich compost.


Coffee grounds help to make quality compost by adding nitrogen to the mix. By the way coffee filters from drip filter machines can be added to the compost as well.

Valuable for their contribution of adding nitrogen, magnesium, potassium, calcium and trace minerals to the composting mix.


Coffee Ground Fertilizer Tea

If you don’t have a compost bin … yet, coffee grounds can be used to make a liquid fertilizer for garden plants. Dilute 2 cups of grounds in a 5 gallon bucket of water. Leave to steep overnight or for a few hours to make the ‘tea’. 


This can can used in a spray bottle to spray on leaves and plants as well as a fertilizer for the soil.


Feed the worms

Earthworms love coffee grounds. By adding grounds to compost materials, when the fertilizer is mixed with the garden soil an ideal environment is created to attract earthworms to the garden. Earthworms play an important role in soil health. Providing aeration and nourishment to the soil as they move through.


Worm Farm

Just as the worm farm will benefit from adding Old coffee grounds can be recycled with  kitchen scraps recycled to feed and nourish worms. Castings from the worms are simply the processed matter creating an organic fertilizer and a juice or liquid fertilizer.







As compost breaks down it becomes a rich, organic material to add to soil as fertilizer. The benefits to soil are many. Improved water retention, improved drainage, improved aeration of the soil and encourages earthworms which themselves nurture a healthier soil.


The role old, used coffee grounds play in this process is that of encouraging micro-organisms valuable to healthy plant growth.
