If blades break inside your grinder, it’ll leave larger pieces of unground weed.
Sharpening the blades also increases the distance between them, so they may not grind your weed to a consistent size.
Get a metal herb grinder if you can since they’re more durable and last longer than a plastic grinder. Clean your grinder once a week if you use it every day or once a month if you only use it every few days. [2] X Research source
Plastic grinders usually have 2 pieces that both have blades. Some grinders have additional pieces, like a mesh screen and a bottom tray.
You don’t have to freeze your grinder, but it would be helpful if you’re grinding weed. Freezing lets you collect more kief, which is potent residue that falls off of weed as you grind it. You can smoke or use the kief that you clean out of your grinder.
Be gentle with the cotton swab so it doesn’t get caught or stuck in the blades. You don’t need to scrub all the residue off yet since you’ll do a deeper clean later on.
If you use a bag, place your grinder inside carefully so the blades don’t slice through it. Isopropyl alcohol is the best way to clean residue off of a metal grinder, like a SharpStone. If you’re cleaning a plastic or acrylic grinder, put the pieces in gently boiling water for 1 minute instead of using isopropyl alcohol. [7] X Research source
Be extra careful if you’re scrubbing a mesh screen so you don’t accidentally poke a hole through it.
Avoid assembling a metal grinder while it’s still wet since it could cause rust to form.
