How to Clean a Grinder Screen

What is Kief?

Don’t Grind Your Gears, Grind Your Herbs!

The benefits of cleaning grinder screens don’t just come in the form of kief.  Having a clean grinder can benefit your smoking experience in multiple ways. Let’s talk about those:

Benefits of a Clean Grinder

1. Ease of Use

Most seasoned smokers know the struggle of trying to grind your cannabis in a sticky grinder. The teeth of the grinder have a hard time making it through the flower because they are covered in resin and kief. This can make it hard to rotate the pieces of your grinder.

After cleaning your grinder, you’ll find that the teeth move much more smoothly through the nug. This will ensure that your herb is finely ground, so you get the most bang for your buck.

2. Preserving Strains While Switching

Many cannabis users find that smoking a Sativa strain in the morning and an Indica strain at night can help with productivity and stress. If you only have one grinder, it is important to clean it in between strains to avoid cross-contamination. 

Additionally, different cannabis strains offer different terpene profiles. These can affect the taste and effects of the herb. Cleaning a grinder in between strains can help to keep these terpene profiles intact for the best smoking experience.

3. Presence of Mold and Bacteria

These are two words you probably don’t want to include in your smoking experience.

If any moisture makes it into your grinder, it can cause mold to form. This mold not only affects the taste of your herb but can also cause bronchial and lung issues. Additionally, if you already have allergies or asthma, smoking moldy cannabis can exacerbate those symptoms.

For the best smoking experience, make sure you clean your grinder frequently to avoid contamination (especially if you are an infrequent smoker!)

With there being 22.2 million marijuana users per month, there's bound to be some dirty grinders screens out there.

Having a clean grinder isn't just good for grinding up cannabis. Cleaning your grinder can actually elevate your entire smoking experience by improving the taste and potency of your herbs.

How to Clean a Grinder Screen

Your grinder is full of useable remnants. The method below uses a two-step process in order to get the most leftover product out of your grinder.

Let’s break it down into four easy steps:

1. Gather Your Tools

Before you begin cleaning your grinder, you’ll want to gather some tools. Here are things we need to clean a grinder screen:

  • A freezer
  • A needle or safety pin
  • A scraping tool, such as a guitar pick or pollen scraper
  • Rubbing alcohol or specialty cleaner

Once you’ve got your tools together, it’s time to begin cleaning your grinder. 

2. Place Your Grinder in the Freezer

The first step to cleaning your grinder is removing the built-up kief by placing your grinder in the freezer for 15-20 minutes. Since kief is made up of fat matter, it will get hard while in the freezer. Using your scraper, you can easily scrape this hardened kief off of the screen and grinder and store it for later use. 

If you need a scraper, you can get a pack for free with any purchase from our website!

The safety pin/needle can also come in handy here, as they can be carefully poked through any holes in the grinder that are clogged with kief or resin.

3. Using Rubbing Alcohol or Cleaner

Once you have removed the useable kief from your grinder, it’s time to do the deep clean.

Start by filling up a small container with rubbing alcohol or specialty cleaner. You’ll want to make sure that you have enough in the container to fully submerge each piece of your grinder.  

Place your grinder and grinder screen in the alcohol and let it sit overnight. This will help to loosen up the trichomes that could not be removed manually. If your grinder really doesn’t want to let go of its herb, you may want to take a clean, damp toothbrush to it.

4. Rinse and Repeat

Once you have removed any residue from your grinder, it’s time to rinse. 

Run your grinder under warm water, making sure to rinse off any remaining kief and alcohol. Then, leave your grinder to dry for a few hours. This will ensure that any remaining alcohol has time to evaporate.

What is Kief?

So you’ve cleaned your grinder, but now you have a container full of powdery and sticky herb residue. What do you do with this?

Do not throw it away! 

No, seriously. Do not throw it away!

Kief, sometimes referred to as “keef” or “dust,” is a highly concentrated collection of loose trichomes from your cannabis flower. These sparkly, resinous bits of herb pack a punch. In fact, it contains a much higher concentration of THC and other psychoactive cannabinoids than normal flower.

There are many uses for kief. Between being vaporized, smoked, or added to flower as a “seasoning” of sorts, it can elevate your smoking experience. Be careful, though, as kief is very strong. You should only use a small amount.

Don’t Grind Your Gears, Grind Your Herbs!

Smoking cannabis is meant to be relaxing. Clean your grinder screen and don't let a clogged grinder get in the way of that!
