A dirty grinder is a vibe-killer. It messes up your grind, ruins airflow, and starts tasting like yesterday’s bad decisions. Here’s the TBBC-approved guide to cleaning and caring for your grinder so it stays smooth, sharp, and sesh-ready.

Why cleaning your grinder matters

  • Better grind consistency: Clean teeth = fluffy, even herb
  • Smoother rolls & bowls: Less clogging, better airflow
  • Better taste: Old residue = stale flavor
  • Longer life: Less wear, less sticking, fewer broken parts

What type of grinder do you have?

Different materials need different love:

What you’ll need

  • Soft brush or old toothbrush
  • Cotton buds (Q-tips)
  • Microfiber cloth
  • Toothpick or wooden skewe
  • Zip-lock bag or container
  • Warm water + mild dish soap (for non-wood)
  • Isopropyl alcohol (70%+) (for metal; use carefully)

Quick clean (5 minutes) — weekly routine

  1. Empty it out: Tap gently to remove loose bits.
  2. Brush it down: Use a soft brush on teeth, screen, and edges.
  3. Detail the corners: Use a toothpick/skewer for stuck residue
  4. Wipe & reassemble: Microfiber cloth, then put it back together.

Deep clean (15–25 minutes) — monthly routine

For metal grinders

  1. Disassemble fully: Lid, chamber, screen, catcher.
  2. Soak (optional): Warm soapy water for 10 minutes.
  3. Alcohol clean: Use isopropyl on a cloth/Q-tip for sticky resin.
  4. Scrub gently: Teeth + threads + screen.
  5. Rinse & dry completely: Air dry before reassembling.

For acrylic grinders

  1. Skip alcohol: It can damage acrylic.
  2. Warm soapy wipe: Use a cloth, not a long soak.
  3. Brush gently: Avoid harsh scrubbing.
  4. Dry fully: Moisture is the enemy.

For wooden grinders

  1. No soaking, no alcohol.
  2. Dry brush only: Use a soft brush to remove residue.
  3. Barely damp wipe (if needed): Then dry immediately.
  4. Keep it conditioned: If your wood finish allows, a tiny bit of food-safe mineral oil on the outside (not inside) keeps it looking fresh.

Screen care (kief catcher grinders)

  • Brush lightly—screens can bend.
  • If clogged, use a Q-tip with a tiny amount of alcohol (metal only), then dry.
  • Don’t poke aggressively; you’ll tear the mesh.

TBBC pro tips (so your grinder stays buttery)

  • Freeze trick (metal only): Pop the grinder in the freezer for 20–30 minutes, then tap/brush—resin flakes off easier.
  • Don’t over-tighten: Cross-threading kills grinders.
  • Keep it dry: Moist herb = sticky teeth.
  • Use a tray: Less mess, less grit, less wasted goodness.

Common mistakes to avoid

  • Using alcohol on acrylic or wood
  • Soaking wooden grinders
  • Scraping with metal tools (damages teeth/screen)
  • Reassembling while damp (hello rust/mold)

Stoner Summary

Clean grinder = clean sesh. Do the quick clean weekly, deep clean monthly, and your grinder will keep serving fluffy, even grinds with zero drama.
