Disassemble your grinder and place them in the freezer for 30 minutes to an hour. By putting your grinder in the freezer, you are allowing any kief to go from soft and sticky, to hard and brittle. A freezing grinder makes it easier for the substance to break free from the sides and screen. You will then want to remove the parts and tap out each piece over a paper towel or paper plate on a hard surface, this will allow your kief to fall into the chamber . 

Step 2: After Freezing, Cleaning Your Grinder is Easy 

You will next want to take each part of the grinder and hit it against a paper plate or on a hard surface. This will allow your kief to fall into the chamber for collecting. Once you see the amount of kief that you are actually saving, you will be amazed.

Thanks much! Hope it works


Quick question. Does this effect the magnet at all? I ask because I literally washed an old grinder with tap water and Dawn and the cap lost magnetization. I don’t know if there’s an ingredient in the soap or maybe too much iron in the tap water and that’s why this happened but I’m hesitant to do anything to my nice new Kozo grinder.


Was looking around the internet to get the best and most effective way to clean my grinder , DHC didn’t disappoint. This thing feels like I just bought it . 👍
