The Grower’s Ritual: How to Properly Clean Your Grinder
Let’s be honest. Your grinder is probably disgusting. It’s sticky, hard to turn, and caked with the ghosts of a hundred past sessions. We’ve all been there.
But here’s a secret from one grower to another: cleaning your grinder shouldn’t be a rescue mission you perform once it’s completely seized up. It should be a weekly ritual. A little bit of regular maintenance is a thousand times easier than a major deep clean, and it ensures every session is as fresh and flavorful as the last.

The First Commandment: Rescue the Kief!
But wait. Before you touch a drop of alcohol or soap, we must save the magic dust. That precious, potent kief in the bottom chamber is gold. You don’t want to wash that down the drain.
Here’s the only trick you’ll ever need: Toss your grinder in the freezer for 30 minutes.
This makes all that sticky, gooey resin hard and brittle. After half an hour, take it out, tap it on a hard surface, and then use a small, stiff brush (a clean toothbrush or a paintbrush works great) to sweep all that glorious kief out of the screen and into a safe container. Rescue the kief, then you can start the cleaning.

Your Battle Plan: Two Ways to Clean
Forget all the complicated methods. There are really only two ways you need to know.
1. The Deep Clean (For Metal Grinders)
This is for when your grinder is a sticky mess. Take it completely apart and soak all the metal pieces in a bowl of isopropyl alcohol (90% or higher) for about 30 minutes. This will dissolve even the most stubborn resin from sticky strains like Gorilla Glue #4. After the soak, use a brush to scrub out the threads and teeth, then rinse it thoroughly with hot water.
And here’s a pro tip for the final step: after rinsing, let all the parts sit out in the direct sun for a day. The UV light and heat will help evaporate any lingering alcohol residue, leaving your grinder perfectly clean and neutral for the next grind.
2. The Gentle Clean (For Plastic Grinders & Weekly Maintenance)
This is your go-to for regular upkeep. Warm water and a bit of dish soap are all you need. Give it a good scrub with a brush, rinse it well, and let it dry completely. This is the only method you should use for plastic grinders, as alcohol can degrade and damage the plastic over time.
The “Don’t You Dare” List: Common Mistakes
- DO NOT use harsh household chemicals. I’ve heard people talk about using degreasers, and it’s a terrible idea. You don’t want that toxic residue anywhere near the cannabis you’re about to consume.
- DO NOT use boiling water on a plastic grinder. You will warp and ruin it.
- DO NOT reassemble your metal grinder until it is 100% bone dry. Any trapped moisture will lead to rust and corrosion.
A clean grinder is a sign of respect for your tools, for your flower, and for the experience. When you Cultivate beautiful, resinous Homegrown cannabis like Girl Scout Cookies or Amnesia Haze, you owe it to yourself to taste the pure flavor of the plant, not the gunk from last month. Nurture your tools, and they will help you Thrive.
Frequently Asked Questions
How often should I really clean my grinder?
The best practice is a quick, gentle clean once a week to prevent buildup. A full, deep clean with alcohol should be done whenever it starts to get sticky or hard to turn, maybe once a month depending on your usage. Regular maintenance is much easier than a major salvage operation.
What’s the absolute best way to save my kief before cleaning?
The freezer method. Hands down. Putting your grinder in the freezer for 30 minutes makes the resin brittle and easy to knock off. You’ll be able to brush out way more kief than you would at room temperature, ensuring none of that magic dust goes to waste.
Can I use isopropyl alcohol to clean my plastic grinder?
No, you really shouldn’t. Isopropyl alcohol can be too harsh for many types of plastic, causing them to degrade, crack, or become cloudy over time. Stick to warm, soapy water for plastic grinders.
What’s the biggest mistake people make when cleaning their grinder?
Using the wrong cleaning agent. People reach for harsh household chemicals like degreasers or oven cleaner, thinking “stronger is better.” This is incredibly dangerous, as these products can leave toxic residues that you absolutely do not want to inhale. Stick to isopropyl alcohol for metal and soap and water for plastic.
