Keep your grinder operating its best with these blade-sharpening and troubleshooting tips.

I am enamored with my coffee grinder. There is nothing like the smell of fresh ground coffee in the morning, or the feeling of creating my own spice blends during grilling season. Unfortunately, if you don't clean your coffee grinder after each use, it can turn into a clogged mess!

If the grinder runs sporadically or won't turn off the switch may be clogged. Make sure the unit is unplugged from the wall and use a soft bristled toothbrush to clean around the switch. A toothpick can help you loosen anything that has gotten caught. Plug the grinder back in and test. If it's still a problem, you may need to disassemble and clean the switch from the inside.

If the grinder wobbles and vibrates when you're running it, the blade may be bent. Make sure the machine is unplugged and then check to see if the blade is even and secure. If it appears loose or damaged you will want to replace the blade assembly.

The secret to keeping your coffee grinder working its best? Plain old, uncooked white rice. Grab a handful of white rice (about a half a cup, uncooked) and put it into the coffee reservoir. Grind up the rice just like you would the coffee. The rice will accomplish a couple of things. First, it will clean any residue from coffee or spices from the bowl and blades of the grinder. While it's doing that, it will also sharpen the blades. Once the rice is ground, dump it and use a soft paintbrush to clean out any rice dust.

    Horsefeathers! Grinder blades are dulled by repeated impacts with hard coffee beans. How, oh how, can repeated impacts with (less) hard rice grains reverse the problem?

    Maybe because the rice acts as a dessicant (just as it does when you add a few grains to a salt cellar). The rice might sharpen the blades by the fact that acts like leather on a cut-throat razor - the rice dust rubbing against the blades could possibly polish them and remove the stickier coffee bean residue? Just a thought

    My theory is that the rice will absorb the oily coffee dust - coffee has a good bit of oil in it which helps cause it to stick. The ground up rice could latch on to the oily grounds and make them dry enough that they don't stick as easy.
    Just a theory.

    Can this same theory be used for a grinder in a coffee pot.
