Ask The Experts: How Should I Clean My Grinder?
This entry was posted on April 19, 2009.
Your grinder may have a few nasty habits it's not too proud of: Namely, it's clingy and has difficulty getting rid of things. While we appreciate the packrat sentiment, it's important that you motivate your grinder to regularly clean up its act -- and since it's an inanimate object, you'll have to take the lead.
Depending on how much you grind, you'll want to remove excess grounds from the burrs on a regular basis -- home grinders should do this monthly, while cafe grinders will need to do it weekly. If it's easy for you to pop out the burrs on your grinder, do so and thoroughly brush the burrs free of any built up coffee grounds. If you can't easily get at the burrs, you can use a product such as Grindz, which is a hard, starchy product designed to clear out the oils and lodged particles from the burrs.
We have heard that some people use raw rice or wheat to achieve the same results as Grindz, which is a wheat-based food-friendly product. However, we haven't tried this out and don't know how successful or safe it is for your burrs.
In addition to the maintenance on the burrs, we also recommend wiping out the hopper regularly to cut down on oily build up that could become rancid over time.
