Quick Answer
Most grinding problems come down to resin buildup gumming up the teeth, an overpacked chamber, or material that’s too wet or too dry for clean shredding. Disassemble and clean the teeth first — that fixes the majority of cases before you consider the grinder faulty.
A grinder that used to work fine and suddenly feels stuck or produces an uneven grind almost always has a maintenance cause, not a mechanical defect. Work through these in order.
Resin Buildup on the Teeth
Sticky resin coats the teeth over time, dulling their cutting edge and making them push material around instead of shredding it. Disassemble the grinder and scrub the teeth with a small brush and isopropyl alcohol, then let it dry fully before reassembling.
Overpacking the Chamber
Cramming too much material in at once prevents the teeth from moving freely against each other, causing the top to stick or turn with resistance. Grind in smaller batches — it’s faster overall since each batch grinds cleanly instead of jamming.
Material Moisture Level
Herb that’s too dry crumbles into dust instead of an even grind, while herb that’s too moist gums up the teeth and screen. If grinding consistently produces one of these results, the issue is likely the material’s moisture level, not the grinder itself.
Worn or Damaged Teeth
If cleaning doesn’t restore performance, inspect the teeth for visible wear or damage — over years of use, teeth can dull to the point where no amount of cleaning restores a clean cut, and at that point replacement is the practical fix.
Grinder Troubleshooting Guide
| Symptom | Likely Cause | Fix |
|---|---|---|
| Sticky, hard to turn | Resin buildup | Disassemble, clean with alcohol |
| Uneven, chunky grind | Overpacked chamber | Grind smaller batches |
| Turns to dust | Material too dry | Adjust storage humidity |
| Gums up quickly | Material too moist | Let herb dry slightly before grinding |

Frequently Asked Questions
How often should a grinder be cleaned?
Every few weeks of regular use, or sooner if you notice resistance or a gummy feel when turning.
Can I use water to clean a metal grinder?
Isopropyl alcohol is more effective at dissolving resin than water alone; a hot water soak followed by a brush works as a milder alternative.
Why does my grinder suddenly feel loose instead of stuck?
Loose, wobbly turning usually points to worn or stripped magnets or threading rather than a cleaning issue, which typically means replacement.
Is it normal for a grinder to get harder to turn over time even with cleaning?
Some resistance increase is normal as teeth pick up microscopic residue, but a well-maintained grinder shouldn’t degrade significantly if cleaned regularly.
Final Thoughts
Before assuming a grinder is broken, disassemble and clean it thoroughly — resin buildup and overpacking cause the overwhelming majority of grinding problems, and both are free, five-minute fixes.
