Guide to Cleaning Your Grinder

As a Maryland medical marijuana patient, it’s important to educate yourself on the health and safety of caring for your marijuana equipment and tools. This includes learning to properly clean and store your cannabis products, such as a grinder. Depending on the amount of daily/weekly use, a grinder should be thoroughly cleaned every one to two months. The more frequently you use your grinder, the more build-ups you will have on the surface. There are a number of reasons to keep your grinder clean, as this prevents you from getting ill, ensures high quality function, and helps keep a long lifespan. In this guide to cleaning your grinder, the experts at Mary and Main will go through the steps of knowing when to clean your grinder and the proper way to do so.

Gather Your Grinder Cleaning Items

  • Toothpicks
  • Toothbrush
  • Isopropyl alcohol
  • Large container
  • Cotton Ball
  • Clean towel

Step One: Rid the Grinder of Kief

It is common for excess marijuana to be left in the grinder. Take time cleaning off the kief from the sides and teeth of the grinder before beginning the alcohol treatment. Toothpicks are an easy tool to use to loosen small cannabis particles. Be sure to do this over a paper plate to catch the leftovers!

Step Two: Gently Clean the Screen

When dissembling your grinder, you will see a screen that will appear dirty after heavy use. Gently scrub a clean, dry toothbrush over the screen to clear the area of loose fragments. It’s important to not overly scrub, as this screen is fragile and can easily be torn.

Step Three: Fill Large Container With Isopropyl Alcohol

Lastly, you will want to soak the grinder in isopropyl alcohol to disinfect and completely clean each piece. Submerge each piece of the grinder into the container for 25 minutes. Once time is up, gently rub a cotton ball over the pieces to pick up any leftover residue. Once each piece is clean, run under hot water then place on a clean towel to air dry.
