Keeping your herb grinder clean not only extends its life but also improves performance and taste. Over time, sticky residue and fine particles can build up, making your grinder hard to twist and less effective. In this guide, we’ll show you how to clean a grinder quickly and safely—whether it's a 4-piece zinc alloy grinder or a simple 2-layer design.

Why Should You Clean Your Grinder?

A dirty grinder can:

Affect the quality of your herbs
Cause parts to jam or wear down
Attract bacteria or mold in humid conditionsRoutine grinder maintenance ensures smoother grinding and keeps everything sanitary.

What You’ll Need

Before you begin, gather the following:

Isopropyl alcohol (at least 90%)
A soft toothbrush or small brush
A container or bowl
Cotton swabs or a microfiber cloth
Freezer (optional, for sticky residue)

Step-by-Step: How to Clean Your Grinder

Step 1: Disassemble the GrinderTake apart your grinder into its separate layers—lid, grinding chamber, mesh screen, and bottom kief catcher (if it's a 4-piece grinder).

Step 2: Freeze for Easier Scraping (Optional)Place the parts in the freezer for 20–30 minutes. This hardens sticky plant material, making it easier to remove.

Step 3: Brush Out Loose ResidueUse a brush to remove particles stuck in the teeth, corners, or screen. Be gentle with the mesh screen to avoid damage.

Step 4: Soak in AlcoholSoak metal parts in isopropyl alcohol for 10–15 minutes. This dissolves sticky residue and kills germs. For grinders with wood or acrylic parts, avoid soaking—just wipe down with a damp cloth.

Step 5: Rinse and Dry ThoroughlyRinse with warm water and let all parts air dry completely. Avoid using paper towels that may leave behind lint.

Maintenance Tips to Keep Your Grinder in Top Shape

Clean your grinder every 2–4 weeks, depending on usage.

Store it in a dry place with the lid on.
Use a grinder brush regularly to prevent buildup.
