How To Clean Your Metal Grinder

Author Michael Fangmeyer

One of the most common annoyances in the Cannabis Community is a dirty/sticky grinder. We cannot stand when it gets tough to grind and pieces of leftover herb stick up a grinder and make it near impossible to grind and enjoy quality cannabis. However, there are quick and simple ways to revive your grinder and even make use of the leftover material without wasting! 

Use our complete grinder cleaning guide to save yourself time and money! 

 

Signs You Should Clean Your Weed Grinder 

When you should clean your grinder is mostly dependent on how much you use your grinder and how you use it to prepare your herb. 

If you grind more heavily and like a more finely ground herb for topping bowls and packing small pieces, you may need to clean your grinder as often as once a week. 

If you prefer a more loosely ground herb that is more suitable for rolling up joints (it burns more evenly this way) then you may want to clean your grinder every month or so. 

Essentially, if your grinder is making small squeaking noises and has small hard bits of ground up herb stuck to the interior, it needs a good cleaning. 

The Grynder by Stache has an innovative design that is meant to reduce the build-up of kief and small pieces of herb while maintaining the quality of the herb. Check out the assorted colors and styles HERE. 

 

Saving the Kief from the Cleaning Process 

Before you can salvage the kief, put the dirty grinder in the freezer for 15 to 30 minutes. It will make cannabis trichomes brittle and easier to scrape free. Once the grinder is sufficiently chilled/frozen, disassemble the pieces and brush the pieces clean while catching the falling kief somewhere it can be collected and used later. We recommend using a toothpick or toothbrush/pipe cleaner to clean the pieces and avoid damaging the grinder. Collecting onto a rolling tray or similar surface is also recommended. 

 

Solutions for Different Grinder Types 

The appropriate cleaning method to use depends on the type of grinder. Acrylic grinders and Plastic grinders are only safe to clean with warm water and vinegar baking soda blends. Acrylic grinders will melt, and Plastic grinders will deform if the water is too hot. Hard brushes can also damage Acrylic and Plastic models. 

Metal grinders can be cleaned using isopropyl alcohol (rubbing alcohol) and coarse salt or plain boiling hot water. The following steps apply only to metal grinders: 

 

5 Steps to Clean Your Metal Grinders 

  1. Before immersing pieces of the grinder into isopropyl alcohol, take a minute or two to give the pieces a thorough hot water wash and then dry them properly. (This should help reduce the amount of necessary isopropyl alcohol.) 
  2. Fill a container or bag with isopropyl alcohol and coarse salt. We recommend a zip-lock or plastic bag that is easily disposed of. Place the pieces that need cleaning into the bag. 
  3. Shake the bag every 10 minutes or so to make sure the pieces are fully soaked and covered. 
  4. Depending on the level of buildup on the pieces, you may need to soak the pieces from anywhere between 20 minutes to over an hour. 
  5. If there is still plant matter/kief remaining, use a brush and/or paper towel to clean the areas until you are satisfied with the results.  

WARNING: Do not smoke or consume any material soaked in isopropyl alcohol.
