How to Clean a Grinder Screen

Weed grinders are one of the primary tools for every cannabis user. They come in a plethora of forms, sizes, and materials, and some of them won’t only slice your cannabis buds into little pieces but will also help to set apart the kief from the rest of the cannabis plant matter. This is possible thanks to a system of chambers that is separated by filters or grinder screens. 

If you are a regular consumer and use your grinder a lot, you will see how sticky trichomes and resin that cover cannabis flowers accumulate and get stuck both to the walls of the grinder as well as the grinder screens. This can be a very annoying thing, especially if your grinder screens are not removable since they can get completely clogged. Luckily for you, we have discovered a couple of methods that will help learn how to clean your grinder screen and leave it as good as new.

There are actually just a few methods to efficiently clean your grinder screens:

One of the easiest and most reliable methods you can use to clean your grinder screen is putting your whole grinder into the freezer for about 15 to 20 minutes. As the kief and resin are almost exclusively fat matter, this will make the kief clogged to the grid or surface of the grinder screen get hard by the cold.

After your grinder is cold, all you have to do is smack it into a hard surface so that the kief stuck to the grinder screen comes off it, and voilà! You will have your grinder screen way cleaner than before. However, depending on how clogged your grinder is, this method's efficiency may vary. So, if your grinder screen was really really dirty, you may still have some kief stuck to your grinder screen surface. But don't worry, if you're trying to get your grinder screen to factory cleanliness, the next method will be perfect for you.

For this method, you will need to get some rubbing alcohol. The rest is actually very easy. After leaving your grinder soaking in rubbing alcohol overnight, all the trichomes that are clogged to the screen should lose off a bit. Then, pass the grinder screen through a hot water rinse to melt down the rest of the trichomes stuck to the screen’s grid and wash them out. You can use a toothbrush to remove the remains of trichomes left.

After this, we recommend leaving the grinder outside for at least a few hours to let the air out the remaining alcohol that may remain in the grinder screen. Now your grinder should look completely new and ready to use again.

If you have an extremely clogged grinder, we recommend you to combine these two methods so you can first separate the remaining kief from the screen and then finish the cleaning process of your grinder screen by doing a deep cleaning with the rubbing alcohol process. After following these steps, you should end up with a completely clean grinder screen ready to collect your kief once again.
