If you have a plastic grinder, go ahead and skip down to the next section titled, “How to Clean a Plastic Weed Grinder.”

If you have a metal or another kind of grinder, stick around for this step. 

Once all of the resin has been removed (and stored safely for later use), submerge the parts of the grinder into a container or ziplock bag of isopropyl alcohol. Be sure that all parts are covered by the alcohol. 

This step will ensure that all residue has been removed. 

You will notice that the liquid in the bag will turn a light brown color. This is just the excess resin floating off the ‘hard to reach’ parts of your grinder, making it cleaner and ready to use again. 

If you do not feel comfortable using isopropyl alcohol, you can purchase solutions designed to clean resin.
