How to Clean Weed Grinder

The biggest issue with grinders is that they get filled with dirty substances, such as small pieces of plants, powdery kief, and sticky resin. When the grinder gets stuck and is difficult to work with, it is time to clean it. 

You will need to disassemble the dirty grinder, soak the grinder in alcohol, scrub it, then rinse and dry the grinder. We recommend cleaning the grinder frequently to prevent build-up, expand its lifespan, and save money to buy a new one when the one you have stops working.

What Is the Easiest Way to Clean a Grinder - Step-By-Step Guide

There are two ways to clean your grinder. We recommend the first one, which is simple and fast when your grinder is not very dirty. The second one is a bit longer and requires extra steps, making it ideal for deep cleaning your grinder. Now, here are the possible options:

A simple way to clean your grinder

1. Disassemble the dirty grinder

You should first disassemble and separate each chamber of your grinder. Next, gather the leftover plant material, such as powdery kief, and save as much as possible. 

You can use this kief in many ways, like putting it in a joint on the inside or coating the outside. And if you need a game-changer for efficiency, quality, and consistency, check out the best kief coating machine.

2. Soak the grinder in alcohol

Put the grinder into a container, such as a Ziploc bag or large glass jar. You should fill the container with isopropyl alcohol and fully immerse all grinder’s parts. Let the grinder soak for 20-30 minutes, and shake the container occasionally to break the residue.

3. Scrub the grinder

Once you pour out the alcohol, scrub your grinder with a brush. We advise you to wash each chamber.

4. Rinse and dry the grinder

Rinse your grinder with warm, clean water. Make sure to rinse all alcohol and residues. Then, wipe the grinder with a clean towel. Wait until the grinder is completely dry before starting to use it again.

Deep cleaning of your grinder — Alcohol and freezer method

1. Dismantle the grinder

In case your grinder is blocked with plant residue that cannot be cleaned the first way, you should do a deep cleaning. So, disassemble the grinder first and carefully remove any chamber from the other. 

2. Throw away the residue

Throw away the leftover plants into a bowl because you can use the material later. At this point, do not worry about the material stuck inside your grinder.

3. Freeze the grinder

Put each piece of the grinder in the freezer to sit upright and leave the grinder in the freezer for 30 minutes. Freezing the grinder makes the residue stiffer. This makes scraping the residue easier.

4. Scrap the plant residue

Once you remove the grinder from the freezer, clean it with a toothpick or soft brush to scrape away as much residue as possible. We recommend scrapping around the chambers’ edges. Most of the residue, like the powdery kief, is potent and rich in cannabinoids, so we advise you to keep everything you harvest for future use.

5. Soak in alcohol

When you have cleaned as much of the leftover plant material as possible, put each chamber into a large Ziploc bag or a glass jar. Fill the container with alcohol and let the grinder immerse. 

Now, leave the parts in alcohol for about 20 minutes. We advise you to shake the containers occasionally to break any part stuck to the grinder.

Additional tip: If you are interested in how to clean a metal grinder, follow our advice: add salt and alcohol to the grinder and shake it nicely.

6. Clean off, rinse, and dry

Once you remove the grinder from the container, clean it with a toothbrush. Then, rinse the grinder thoroughly in clean, hot water to ensure all the alcohol and cannabis flower residue is gone. Dry off the grinder with a clean towel.

Soap and water method

If you have a plastic grinder, you can use another method: soap and water. You should follow the simple steps on how to clean a plastic grinder:

  1. Disassemble the grinder.

  2. Place the pieces in a bowl or container that can handle hot water.

  3. Fill the container with hot water and let the grinder soak for 15 minutes.

  4. Add dish soap to the water and then clean with a soft brush.

  5. Rinse the arts with warm water and let them dry before use.

But will boiling a weed grinder clean it? Boiling your grinder works just as well as cleaning it with alcohol, but remember that this can be done only on metal grinders.
