Fortunately, cleaning a weed grinder is a relatively simple process that can be done with just a few household items.

The exact method you use will depend on the type of grinder you have and the materials it is made from.

In this guide, we will walk you through cleaning your metal, wooden or even plastic grinder by several different and popular methods to get the best results.

What is a Weed Grinder? Different Types? Benefits? 

A grinder, often known as a weed grinder, is a small device made to grind herbs, such as tobacco or cannabis, into fine particles.

The grinder achieves this through the use of various sharp components which can be rotated to cut and grind the herbs.

It can save you time compared to pulling apart your herbs or cutting them up with scissors.

In addition, grinding makes the herb particles a consistent size which means an even burn, so you get an improved taste and a better smoking experience.

Grinders can be made from a variety of materials, including metal, wooden, plastic, Acrylic, and more.

While grinders of other materials can serve as a backup option, metal grinders are definitely superior in terms of durability, performance, and health safety.

Your grinder may have two, three, four, or even more components held together with a magnet or screwed on tightly.

How to Clean Your Weed Grinder with Isopropyl Alcohol?

Cleaning your weed grinder doesn't have to be a hassle. Discover the easy and effective way to keep your grinder in top shape with our take on how to clean a grinder with Isopropyl Alcohol.

The most important thing Before cleaning is gathering the right supplies. Having these items on hand will make the cleaning process a lot smoother.

Materials you will need:

90%-99% isopropyl alcohol, A pipe cleaner or nylon brush, Paper towels, A large glassware or resealable plastic bag.

The type of cleaning agent you'll use depends on the material from which your grinder is made. For stainless steel and other metal grinders, isopropyl alcohol ie the best choice.

If your grinder is made of plastic or acrylic, don't use isopropyl alcohol since it may dissolve and damage it. Instead, replace it with warm water mixed with dishwashing soap.

Step 1: Disassemble the Grinder

Open up all the chambers of the grinder to separate them. Take the grinder apart so the alcohol can clean every spot.

Be sure to check if your grinder has removable screens. If it does, take those apart as well.

Make sure that you have a clean area set aside where you can keep tracking of all of the parts, as well as have a guide handy for reassembly.

Step 2: Remove any leftover plant material

Before you get started, dump out any leftover herb onto a plate.

If your grinder has stubborn caked-on resin material, you can place it in the freezer for an hour. Freezing forms loose clumps that are easier to remove.

You can take a toothpick to scrape away any resin you find. But keep in mind, by not freezing it, you won't be able to save all of the residue.

If your grinder has a chamber for collecting kief, use a dry toothbrush or paintbrush to run the bristles over any metal teeth and the kief screen to extract the kief from the grinder.

Store the kief in an airtight glass container, separate from your main stash. Many choose to save the residual material that comes off the grinder, as kief is potent.

Step 3: Soak all the Parts in Alcohol

Find a plastic bag or glass container and put all of your weed grinder parts in it. Then, fill the container up with enough isopropyl alcohol to cover all of the parts. Leave it soaking for at least 30 minutes.

Step 4: Drain and Scrub

Take out all of the parts from the rubbing alcohol.

You can then use a brush or toothbrush with strong enough bristles to remove any remaining dirt or debris.

Make sure to clean the inside and outside of each part, as well as the spaces between the grinders.

Step 5: Rinse and Dry

Once your grinder is polished to perfection, rinse it under warm water. Then, grab a clean rag, and dry it thoroughly.

Step 6: Reassemble your Grinder

Do a quick visual inspection to ensure all the plant matter has been removed, and that all components are fully dry.

Then reassemble your grinder. Grab some dry cannabis flower and get to grinding!

How to Clean a metal grinder with Milk? Step by Step Guide

As strange as it sounds, boiling a grinder in milk is a very effective cleaning method creating a cool result.

The fat in milk breaks down and absorbs the THC on the surface of the grinder. The simmering milk will loosen all the particles stuck to the grinder, making it easier to scrape out.

You get a clean grinder, and the byproduct is some THC-infused milk - perfect for a delightful cup of hot chocolate.

Before you try boiling the grinder in milk or water, be sure to understand that cleaning the grinder in this way can only be done with metal grinders.

Plastic or painted grinders may soak toxins into the liquid when boiled. Boiling plastic or wooden grinders can ruin them.

Materials You Will Need:

First, gather everything you need: A dirty grinder, A Double boiler and stovetop, A strainer, Milk - Whole milk works best because of its higher fat content.

A double boiler is a large pot that is partially filled with water. Inside that is a second smaller pot, and this is where you place the milk.

If you don't have a double boiler, you can create a double boiler using a pot with a small amount of water and another pot that sits inside of that pot.

If you are vegan, choose your favorite type of milk (cashew, oatmeal, coconut, or almond milk), but choose the high-fat version over the low-fat version.

Step 1: Disassemble the grinder

Disassemble the grinder, taking the chambers apart.

Gently tap all parts of the grinder to loosen and remove plant material.

Step 2: Fill the Double boiler with Water and Milk

Fill the bottom of the double boiler halfway with water.

Add the milk to the top interior pot so it is half full.

Step 3: Put the parts into milk

Place the grinder parts in the milk and turn the stovetop to medium-high hea.

Step 4: Boil the milk

Bring the water to a boil, and the milk will begin to simmer.

Reduce the heat so the water continues to steam, and the milk simmers gently. You do not want the milk to get to boiling as it will scald.

Heat the milk gently for about an hour, then cut the heat off and let it cool.

The water in the large pot will create steam. The heat will transfer to the milk in the smaller pot but at a slower rate than heating it directly. This prevents it from boiling, and where the sugars burn, and the milk curdles.

Step 5: Rinse the grinder parts

Remove the grinder parts from the milk and clean any remaining material off with soap and warm water, then dry the parts on paper towels.

Step 6: Strain THC-infused milk

Strain the now THC-infused milk to remove any particulate matter. You can drink this now if you dare.

Usually You need to ensure the outside of the metal grinder is clean so that you don't introduce dirt or other yucky non-weed material to the milk.

How to Clean a Wooden Grinder?

Afterwards, take it out of the freezer and softly scrape the areas with resin bits stuck to them, either using a toothbrush or any object with slightly sharp points. It is very important to not press hard to avoid creating notches or indentations.

How often should I clean my grinder?

Clean as often as necessary, which is to say: It depends on how much use your grinder receives and how dirty it gets, but more often than never.
