Rinse and Dry the Grinder (Photo by: Gina Coleman/Weedmaps) Method 2: Deep Clean Your Grinder. If your grinder is so clogged up with plant residue that it’s hard to get a smooth back-and-forth grinding or slicing motion, it’s time to deep clean it. Start by disassembling the grinder and removing each chamber from the others.
As you do this, be careful that you don’t spill any of the plant matter that’s left over inside the chambers. Disassemble the Dirty Grinder (Photo by: Gina Coleman/Weedmaps) Step 2: Dump Out Residue. Dump out leftover plant matter onto a plate or into a bowl. At this point, you’re simply trying to harvest the stuff that’s only loosely caked into the grinder; don’t worry about the material still clinging to the chambers of your grinder.

Leave the grinder in the freezer for at least 30 minutes.
Freezing the plant residue this way makes it stiffer and, as it freezes, it will start forming into small clumps rather than clinging tightly to the grinder, all of which simplifies the scraping of the residue out of the grinder.

As before, use your plate or bowl to collect everything. Remember to scrape around the edges of all the chambers, along the sides of the grinding teeth, and around the circumference of each chamber’s lid. Most of this plant residue—especially the powdery kief—is incredibly rich in cannabinoids and very potent, so be sure you keep everything you harvest for future use.

When you’re satisfied that you’ve harvested as much of the leftover plant material as you possibly can, it’s time to make your grinder spotless. Place each chamber inside a large Ziploc bag or a glass jar. Fill the container with enough isopropyl alcohol to fully submerge the grinder. Every once in a while, give the container a gentle swirl to help break apart any plant matter stuck to the grinder. Soak in Alcohol (Photo by: Gina Coleman/Weedmaps) Step 5: Clean Off Remaining Residue. Pour out the alcohol and remove the grinder from the container. Use a toothbrush or another stiff brush to scrub your grinder clean. In this step, you’ll get rid of the most tenacious residue—the stuff that’s really gunking up your grinder and making it hard to use.

Finally, give the grinder a good rinse in clean hot water, making sure that all the alcohol and plant residue are gone. Use a clean towel to dry off the grinder, including inside the chambers and around the grinding teeth. Rinse and Dry (Photo by: Gina Coleman/Weedmaps) Step 7: Start Grinding Again. At this point, your grinder should be pretty much spotless—almost as clean as the day you first got it. You will immediately notice how smoothly the device rotates and grinds, and how much neater and more uniform your small chunks of herb will become. When your grinder is completely dry and in like-new condition, go ahead and load up a few nugs, grind them down, and enjoy your smoke.

A clean grinder is essential to getting the most out of your cannabis experience, and you can keep your device in top condition with a few household supplies along with a little elbow grease.

Weed collects over time, making them harder to use and way less effective. Here are a few tips for keeping your grinder nice and clean (and shaving valuable seconds off of your rolling time). This is actually a good place to start before getting into the manual cleaning process (especially if your grinder is in need of a real deep clean). Take your grinder apart and place each of the separate parts into your freezer. You won’t need more than 30 minutes to an hour; just long enough for that stubborn, sticky plant matter that can coat the inside of your grinder to freeze, making it far easier to dislodge. Try putting your grinder back together and giving it a good, hard shake; open it up and much of the troublesome stuff should fall right out. You might have stumbled across this method in desperation, but it’s actually effective; a toothbrush can get right into the nooks and crannies between the teeth. If you’re using a more complex grinder, this is also the perfect piece of equipment to use on the mesh grinder screen used to collect kief; just be gentle, as this part of the grinder is much easier to damage than the other sturdier ones.
No need for toothpaste though, and tempting as it may, you’ll probably want to wash it off before using it on your teeth again. This is the best method for giving your grinder a deep, exfoliating cleanse and have it looking brand new. Pick up a bottle of ISO (Isopropyl) rubbing alcohol; this is strong enough to really break down those stubborn bits of weed gunk that might stand up to toothbrushes or water get lodged into the grinder. You can choose to either take the grinder apart and let it soak totally in a bowl of the alcohol or (perhaps if your grinder is made of more delicate material) use a q-tip to dab the alcohol into problem areas.
