There are lots of ways to clean a coffee or spice grinder out there. I've previously tried using bread but found it gummed up and wasn't very efficient. I also tried both sugar and salt, but those seemed too fine to really grab all of the oily coffee grounds.

So how do I clean my coffee grinder? A small amount of rice and a paintbrush or toothbrush. Easy! :D

P.S. Don't ever clean your coffee grinder? You should give it a try! The oils from the coffee beans can go rancid over time, so you may be pleasantly surprised at how much better your coffee tastes after cleaning your grinder.

Step 1: Add the Rice to the Coffee Grinder

For most standard size coffee or spice grinders, you only need 1/4 cup rice. You can use any type of rice you want as long as it's dry and uncooked.

If you have a larger coffee grinder, just add enough rice to cover the blades entirely.

Step 2: Grind It Up

Process the rice until it is a fine powder. It should change in color slightly - turning a very light tan.

Step 3: Pour Out the Powder and Clean Up the Grinder

Tip the rice powder into the trash or a compost bin and then use the paintbrush to scrape out any excess powder.

If your grinder is especially stinky (or if you use it for both spices and coffee!), use a paper towel dipped in plain white vinegar to wipe it out. Keep the lid off and let it air dry completely before using again. The vinegar smell will go away as it dries.

And there you go! Enjoy your fantastically clean coffee grinder. :D

<p>There's a trick to using bread to clean the grinder. I use slices that I've let sit out for 2 days and get good and dry. They won't get gummy and you'll have bread crumbs for use later. </p><p>I use my coffee grinder strictly for grinding herbs and spices. If I know I'm going to need bread crumbs, or I'm just getting low, I'll leave 8 slices of bread out. My grinder tends to stay fairly clean.</p>
I keep a 1 inch basting brush with the grinder and measuring scoop. Every single time I grind coffee I turn the grinder over to get the coffee into the lid, use the brush to clean out the grind chamber into the lid, empty the lid into the coffee maker, and brush the lid out. Takes about 10 extra seconds, but it looks like new and I never need to do a deep cleaning like this.
<p>I use an artist's brush on mine. One with 1/2 inch wide tip. It gets into the spaces beneath the blade.</p>
Yeah, that would work well too. <br>I just used one that I had handy and knew was food safe since it's for basting and never been put in paint, unlike my other brushes.<br>It's served me well.
<p>Nice! I've been doing the exact same thing for years, except I use my old shaving brush after I switched to electric shavers :-)</p>
<p>Looks like you're using the same grinder as me in the instructable, so one question:<br>When I bought the grinder, many Amazon reviews noted that grinding rice generated tiny pits in the plastic lid over time, making it cloudy, and so recommended &quot;softer&quot; starches like bread or paper towel; have you seen any cloudiness develop?</p>
Good one Jessy! Doing this today.
<p>Tomascco,</p><p>How did this work out in your burr grinder?</p><p>Coffee and spices in the same grinder?</p><p>Gives new meaning to &quot;Coffee Thyme&quot; :-)</p>
<p>I just grind a gram of pot every once in a while. Makes the next pot of coffee real relaxing. Ha ha ha just kidding. Or am I</p>
<p>Wonder how this will work in a burr grinder? I'll let you know.</p>
<p>Excellent. This should also work well on similar tools like the blender and food processor.</p>
<p>For blenders I simply add a little water and a drop or 2 of dish washing liquid. Give it a spin for a couple of seconds and it is clean like sparkling new ! </p>
<p>The easist way to clean out a blender of food processor is to put in some water and dish soap and turn it on. Let it run for a few seconds and empty out the soapy water. Rinse and dry. There all clean and ready for use. I've been using this method for well over 30 years :) Damn I'm old!!</p>
<p>yes!! I do that with both my food processor and blender. Works so well. :D</p>
<p>I find a cheap blusher brush (say, from a 99c store) works better than a basting brush because it's softer and picks up the oils better, and can get closer under the blades. I keep the blusher brush by the grinder and whisk it after each use, and it has stayed fresh and bright for years. </p>
<p><strong>Nice</strong>... simple and efficient.</p>
<p>uses for rice flour (created in cleaning process) </p><p>Soap making as natural exfoliant, coffee is a great invigorating ingredient.</p><p>Natural face mask - <strong style="">Ingredients</strong> &ndash; Gram flour, Rice powder, Sugar, Honey and Coconut oil</p><p><strong>Exfoliating Rice Powder Body Scrub for Silky Smooth Skin</strong></p><p>So many more uses </p>
<p>Nice!! Those are great ideas. I think I'll save the next batch. :D </p>
<p>I did this with my grinder that I keep for spices. There was a load of miscellaneous compacted mixed-spice junk in it. Cleaned it like a champ.</p>
<p>Thanx ... If you use brown rice, you can just put the rice powder in a mini keeper and into your freezer; its great for thickening soups, stir fry, stews, puddings, etc. </p>
<p>A few small pieces of paper towel do a good job too.</p>
<p>Great tip, I will try it right now ... Thanks and keep it going!</p>
<p>Muy bueno y super pratico!!!!</p>
<p>Great method. I have to try this. Thanks.</p>
<p>it worked great</p>
<p>Great tip! Thanks.</p>
<p>thanks for posting this</p>
<p>This is great! No longer will I have to keep hoping the grinder will magically clean itself. The gunk is gone!</p>
<p>Awesome! Thanks so much!!</p>
No doubt I'll have to get in it thanks
<p>The brush and the vinegar I knew about although I could never get the cap properly cleaned after a flatmate used it for spices. With the addition of the rice I got that part too! Thanks alot for the tip!</p>
<p>this is the method I use for mine, because I use mine for spices and coffee lol</p>
<p>Thank you!</p>
<p>Thank you so much for this great list!!!</p>
