Keeping Your Grinder Clean (Because You Should)
Let's be real - most people don't clean their grinders nearly enough. I get it, it's not the most exciting task. But a clean grinder is just better in every way, and once you get into a routine, it's really not that bad.
Whether you've got a cannabis grinder, a fancy custom grinder, or just a basic one that gets the job done, keeping it clean makes a noticeable difference.
Why Bother Cleaning?
Here's the thing - that sticky buildup isn't just gross. It's actually messing with your experience.
Flavor suffers: Old residue sitting in there changes how your herbs taste. A clean grinder lets the actual flavor come through.
It works better: Clogged teeth don't grind evenly. You end up with chunks mixed in with powder, which is annoying whether you're rolling or packing a bowl.
Health stuff: Old residue can grow bacteria or mold. Not something you want mixing with fresh herb.
It lasts longer: Regular cleaning prevents wear and tear. Take care of your grinder and it'll take care of you for years.
Types of Grinders
How you clean depends on what you've got:
Two-Piece Grinders
The simplest kind - just top and bottom that screw together. No kief catcher, which makes cleaning easier but means you're not collecting kief.
Three-Piece Grinders
These add a third section for catching kief. Takes a bit more work to clean, but that kief collection is worth it.
Four-Piece Grinders
Same as three-piece but with a screen that filters the finest particles. More parts to clean, but you get the most functionality.
How to Actually Clean It
Here's what you need:
- Isopropyl alcohol (91% or higher works best)
- A small brush - old toothbrush is perfect
- Something to scrape with (plastic or silicone, not metal)
- Paper towels
- Warm water
- A container if you're soaking multiple pieces
Step 1: Take It Apart
Unscrew everything. Top, bottom, screens, kief catchers - the whole thing.
Step 2: Brush Off the Loose Stuff
Use your brush to get rid of anything that's not stuck on. Pay attention to the teeth and walls where stuff likes to hide.
Step 3: Soak
Drop everything in isopropyl alcohol for 30-60 minutes. This dissolves all that sticky resin. If you've got a kief catcher, you might want to soak it separately so you don't lose any good stuff.
Step 4: Scrub and Rinse
After soaking, give it another brush to get the stubborn bits. Then rinse everything with warm water. Make sure all the alcohol is gone.
Step 5: Dry Completely
Let it air dry. Don't put it back together until every part is totally dry, or you'll get rust or mold.

Other Ways to Clean
The Freezer Method
If your grinder's really gunked up, stick it in the freezer for a couple hours. The cold makes the resin brittle so it scrapes off easier. Just disassemble it first, toss the pieces in a bag, freeze, then scrape.
Lemon and Baking Soda
If you'd rather skip chemicals, make a paste with lemon juice and baking soda. Spread it on with a brush, let it sit a few minutes, then rinse. Works pretty well.
Making It Last Between Cleans
You don't need to deep clean every time, but a little regular maintenance helps:
- Clean it monthly: Or more if you're grinding daily. Less if you're casual about it.
- Don't overload: Cramming too much in there clogs it up faster. Smaller batches work better anyway.
- Store it right: Keep it somewhere cool and dry. Moisture is bad news.

Don't Make These Mistakes
- Water on electric grinders: If you've got an electric grinder, don't dunk it in water. Use a damp cloth instead.
- Forgetting the kief catcher: Clean it and collect what's in there before you lose it.
- Harsh chemicals: Bleach and other heavy cleaners can leave residue that affects taste. Stick with isopropyl alcohol.
Bottom Line
Cleaning your grinder takes maybe 10 minutes if you do it regularly. That's it. And the payoff - better flavor, smoother grinding, longer-lasting equipment - is totally worth it.
Set a reminder on your phone. Do it once a month. Your grinder (and your taste buds) will thank you.
