How to Clean Your Grinder

Clean your grinder

When buying a portable vaporizer, Australia-wide, it’s essential to make sure that you've got all the tools you need for a quick and easy session; this also means ensuring that all your devices and vape are clean and ready to perform at their best. 

Today we’ll be going over how to clean your grinder, the most essential tool in your session, whether you're using a bong or vaporizer. 

How often Should You Be Cleaning Your Grinder? 

To ensure the best grind of your herbs, with no sticky residue blocking up or impacting its movement, you should ideally be cleaning your grinder regularly. This will ensure that you aren’t consuming any mould or bacteria that may accumulate in your grinder over time. 

If you’re cleaning your grinder regularly, it’ll work better for longer since the plant matter residue won’t cause the blades to make that high-pitched, squealing sound when they rotate. It also means that you’ll be able to collect all that kief properly. 

What You Need

Here's a list of all the equipment you need to clean your grinder: 

  • You’ll need both a stiff and soft-bristled brush to remove all the plant matter from your tool. The best brushes for these would be a paintbrush and toothbrush. 
  • Plate/bowl. Either option works; you just need to ensure that the circumference of your plate or bowl is larger than your grinders chambers. This will ensure that you don’t lose any kief. 
  • Isopropyl Alcohol. You shouldn’t use alcohol to clean your grinder if it's made from plastic or acrylic. If your grinder is made from a metal source, ensure that you’re only using 70-90% isopropyl alcohol.
  • Ziploc Bag. Alternatively, you can use a glass jar; as long as it's large enough to fit your grinder, it’ll work. 
  • You’ll need hot or boiling water. 
  • Choose a soft towel so you don’t scratch your grinders chambers. 

How to Clean Your Grinder


The first step is to disassemble your grinder, making sure to remove all chambers without spilling any leftover plant matter. 

Dump the Residue

Empty any leftover plant matter into a bowl to use another day. Don’t worry about any leftover kief that sticks to the chambers; this’ll be cleaned out soon. 

Into the Freezer

Place each section of your grinder upright into your freezer, leaving it there for at least 30 minutes. The purpose of this step is to make any residue stiff instead of sticky, making them easier to remove later, without wasting any kief. 

Brush and Pick

After about 30 minutes, remove your chambers from the freezer and use your soft-bristled brush to scrape at any plant matter and residue gently. As these pieces loosen, tip them into your bowl or plate. 

It’s essential to make sure that you’re scraping all around the grinder, including the edges, sides and lid. The better you clean these areas, the more kief you’re going to collect. 

Alcohol Rinse

Once you’ve scraped off as much kief as possible, place all your metal chambers into a zip lock bag or glass jar. Fill it with isopropyl alcohol so that the sections are fully submerged. Let them soak for about 20 minutes, swirling them around gently every once in a while. 

If you have an acrylic or plastic grinder, ignore this step and instead pour some boiling water over your chambers before letting it cool and moving on to the next step. 

Brush, Rinse and Dry 

After 20 minutes, open your jar or bag and pour out the alcohol. Then using a hard bristle brush, gently brush your grinder thoroughly. 

All the residue that had built up in your grinder should now come loose. Once you’ve thoroughly brushed every surface, rinse it under hot (not boiling) water, making sure there's no residue leftover. With a clean towel, dry the chambers, the lid, and around the grinding teeth. Now you're ready to start grinding again!
