What Is a Cannabis Grinder?


A Cannabis Grinder is a device you will use to grind your plant materials such as Cannabis flowers, herbs, and spices into smaller pieces so that they can be readily and evenly distributed when smoking or cooking.

Cannabis Grinders can be made of metal or plastic, usually cylindrical, with teeth on the inside. These teeth are designed to break up Cannabis buds into small pieces for consumption.

Choosing the right Cannabis Grinder can be a difficult task. There are three main types:

Fixed Space Weed Grinder

These Grinders feature the same sized holes for all three pieces of material and are usually cheaper than other types.

Step-Size Weed Grinder

These Grinders feature evenly-sized holes in the top part of the Grinder, while the bottom part has holes that gradually get smaller.

Conical Shape Weed Grinder

This type features a curved shape that will push material down towards a hole at the Grinder’s bottom.

Why is it Important to Clean Your Cannabis Grinder?

It is essential to clean your Grinder because it will make your Cannabis last longer. If you use a Grinder that other people have used, the oils and residue from their fingers can get stuck in the Grinder’s teeth. This residue will cause your Cannabis to taste unpleasant and take longer to burn.

Cleaning your Grinder is not just about making sure that it looks nice but also about making sure that you are getting the best quality out of your Cannabis.

When Should You Clean Your Grinder?

When Should You Clean Your Grinder?

How often you clean your Grinder depends on your needs and taste, as well as the type of weed you are smoking. Many factors determine how often a person would need to clean out their Grinder.

The best way to ensure that your weed tastes good and is not covered in the leftover residue is by cleaning it out every couple of uses or after a week or two if using it more frequently.

Many people will find that their Grinders need more frequent cleaning if they smoke a potent kush strain. Stronger strains will leave more residue inside the Grinder than usual, so you should clean these Grinders after every use.

Cannabis Grinders are known to get clogged up with residual Cannabis material. That means the Grinder needs a good cleaning before you can use it again. The type of cleaning method that you use will depend on how difficult the residue is to remove and out of what materials the Grinder is made.

There are many ways to clean a Cannabis Grinder, and there’s no foolproof way, but here’s a list of some of the most popular methods:


Cleaning Your Grinder With (Hot) Water

Cleaning your Cannabis Grinder with hot water is a simple and effective way to eliminate leftover powder residue and debris after grinding. Disassemble your Grinder, and place all components in a bowl of warm water. Use an old toothbrush to loosen any debris. Run under flowing hot water to rinse, and leave to dry completely. 


Cleaning Your Cannabis Grinder With A Lighter

You may be tempted to try using a lighter to clean your Cannabis Grinder, but this will just combust the Cannabis and make it an unpleasant experience.

Cleaning your Grinder with a lighter can lead to two problems. First, it is more complicated than just wiping it out with a cloth, which will leave material on the teeth and inside the top of the Grinder. The second issue comes from the potential for combustion when using fire to clean your instrument, which means you will need even more cleaning afterward.


Cleaning Your Cannabis Grinder With Acetone (Or Nail Polish Remover)

The Cannabis plant produces a sticky resin that can build up in a Grinder, causing residue and gunk to accumulate. Acetone is one of the best ways to get this build-up off your Grinder.

For most Grinders, you will want to use about one inch of acetone at a time. Put almost half of the amount of acetone into the Grinder to saturate all inside surfaces and then just shake or turn your Grinder for about ten seconds. After shaking, you should see less resin in your Grinder after dumping the acetone.


Cleaning Your Cannabis Grinder With Alcohol

Cleaning your Grinder with alcohol is a prevalent practice. Some people do this to remove the smell and taste of Cannabis from their devices. Others clean their devices with alcohol to maintain their durability by removing any dirt or oils on the surface of their Grinder.

Cleaning Your Cannabis Grinder With Milk

Pour an entire carton of milk into the Grinder. Run it for three minutes with water only, and then repeat this process with soap, water, and bleach three more times.

Milk is an excellent alternative for those who don’t like alcohol or dish soap as it doesn’t leave any scent in the Grinder and is also a natural disinfectant. Be sure to rinse your Grinder thoroughly. 


Cleaning Your Cannabis Grinder With Vinegar

The first step is to put your Grinder in a container with enough vinegar and water so it can soak for half an hour. The vinegar will dissolve sticky resin accumulated on the screen and inside of it. Brush off any residue with the toothbrush, then rinse off from the faucet.
