Why Cleaning Your Grinder Matters
Coffee beans contain natural oils. As they are ground, those oils coat internal components and gradually become stale. Even if you can’t see it, the residue builds up and transfers unwanted flavours into fresh beans.
You might notice:
- Coffee tasting slightly bitter or flat
- Inconsistent grind size
- Increased retention of old grounds
- Slower or noisier grinding
Regular cleaning clears trapped particles and oil residue, helping restore consistent grinding and flavour clarity.

Suitable for Burr, Espresso & Bean to Cup Grinders
Grinder cleaning is important whether you use:
- A standalone burr grinder
- An espresso grinder
- A commercial grinder
- A bean to cup machine with a built-in grinder
Most grinder cleaners work by running cleaning granules through the grinder. These absorb oils and dislodge residue without damaging burrs or internal components. Always follow the manufacturer’s guidance before use.
