Take a little brush and have at it. I have like three from old electric razor blades and hair trimmers. I brush it all onto a glass table that was just cleaned and then scrape it all up and smoke.
If it's metal, you can just drop it in a cup of isopropyl. Shake it around for a minute, take it out and rinse it off well, pour the isopropyl on a plate, let it evaporate completely, and scrape up the kief that's left over. You can actually clean your whole grinder this way and smoke the goodies from it.
i have a small but heavy duty ( small ) bristles wire brush works great ! or you can make it simple - ISO... lol
You can use either a toothbrush (please for the sake of all things unholy don't use your current one), or you can put a small coin in the grinder (on top of the screen) and shake it around a bit. The weight and friction should knock most of the kief loose from the screen. You can also let it soak in ISO and then let it evaporate, and you'll still be left will of the remaining kief Happy toking! Sent from my iPhone using Grasscity Forum
