Best Way To Clean a Cheapo Coffee Bean Grinder

A recent clean-out of the dreaded Tupperware cupboard unearthed an old White Westinghouse coffee bean grinder.

We bought it years ago when our old grinder died and we were still deciding what to purchase next. Now I'm thinking it would be ideal to repurpose for spice grinding but I'd like to give it a good clean out first since there's some slight coffee residue in there and it smells of coffee.

Does anyone have a suggestion for the most effective way to do this?

  1. I've heard running through a few batches of raw rice does the trick.

      White bread then raw rice.

      I've also ground up some rolled oats in it into oat flour for cookies and the hint of coffee flavor was great.

        I alsouse a toothpick to clean screws on bottom

    2. Raw rice....rinse-repeat a couple times.Works great.

        +1 on the rice, but "rinse"???? I do a wipe with a damp paper towel, I don't think I'd "rinse" or you're going to ruin the motor.

          1. re: grampart

            Then of course the best way to get rid of the rice residue is to run some coffee beans through it.....

            I meant like shampooing minus the water..and shampoo :)

            Raw rice works great! But what is better is just put the damn thing in the dish washer!!!!!

          4. Actually, you'll want to use a short-cook 'minute rice' type of product. What you're looking to do is absorb oils & displace old grounds. Raw rice is extremely hard on the grinding surfaces & not great at absorbing stale coffee oils. 'Minute' rice (generic is fine) is much more friable & porous, making it a much better grinder cleaner.

            Alternatively, you can buy a product called Grindz, but it's much more expensive & is basically the same thing as generic 'minute' rice.

              That makes sense and I would be relieved of any guilt for wasting good rice. ;-)

            2. In her excellent book on Thai food, "Cracking the Coconut", Su-Mei Yu advises, " (put) 2 to 3 tablespoons of sugar in it and grind for a couple of seconds. Discard the sugar and wipe clean with a paper towel."

                I'd stay with the rice. Why bring something with a possible "sticky" aspect into the operation?

                    Pardon my frustration, but the blade 'grinder' is not even a grinder. it is a 'chopper'. It does not need rice, bread, or any other thing but a clean towel to clean the insides.

              2. I've always used a piece of chewy white bread. Run a small chunk through, dump out the crumbs and repeat until the bread stays white.
