🌿 Quick Clean (After Every Use)
Tools Needed:
- Small brush (toothbrush or included brush)
- Clean cloth or paper towel
- Empty all chambers - Remove all ground material completely
- Brush teeth and chambers - Use brush to remove stuck particles
- Wipe threads - Clean cloth around threading to prevent buildup
- Tap out debris - Gently tap grinder to release loose particles
Keep a small brush with your grinder for immediate cleaning. This 30-second routine prevents major buildup.
🧼 Deep Clean (Weekly/Bi-Weekly)
Tools Needed:
- Isopropyl alcohol 70%+
- Small container or bowl
- Toothbrush or cleaning brush
- Cotton swabs/Q-tips
- Warm water
- Clean towels
- Disassemble completely - Separate all grinder parts
- Collect kief - Save any kief from 4-piece grinders before cleaning
- Soak in alcohol - Submerge metal parts in alcohol for 20-30 minutes
- Scrub gently - Use toothbrush to remove stubborn buildup, especially on teeth
- Clean threads carefully - Use cotton swabs dipped in alcohol for threading
- Rinse thoroughly - Rinse all parts with warm water to remove alcohol
- Dry completely - Pat dry with towel and air dry for 30 minutes minimum
- Reassemble - Put grinder back together only when fully dry
Never reassemble your grinder while parts are still wet. Moisture can cause corrosion and affect performance.
Place grinder parts in a ziplock bag with alcohol and shake vigorously for faster cleaning. This method works especially well for stubborn buildup.
🔧 Monthly Deep Maintenance
- Complete deep clean - Follow all weekly deep clean steps
- Inspect for damage - Check teeth for dulling or breakage
- Clean screen thoroughly (4-piece) - Soak screen separately, brush gently
- Test performance - Grind small amount to ensure smooth operation
For clogged screens, place in freezer for 10 minutes, then tap gently. Frozen particles break free easier.
❌ Common Cleaning Mistakes
Using the dishwasher
Never use dishwashers. High heat and harsh detergents damage grinders. Always hand-clean.
Boiling grinder parts
Boiling can warp metal and damage anodizing. Stick to alcohol soaking instead.
Using harsh chemicals
Bleach, acetone, and harsh cleaners damage grinders. Use only isopropyl alcohol and warm water.
Scrubbing screens aggressively
Harsh scrubbing tears mesh screens. Use gentle brushing and soaking instead.
Not drying completely
Moisture causes rust and corrosion. Always air dry for at least 30 minutes after cleaning.
Wrong size for usage frequency
Smaller grinders are easier to clean but require more frequent cleaning. See our grinder size guide to match size with your maintenance commitment.
🔍 Troubleshooting Common Issues
Sticky or Tight Threads
Solution: Deep clean with alcohol focus on threads. Apply tiny amount of food-grade lubricant. Work threads several times to distribute evenly.
Clogged Screen (4-Piece)
Solution: Freeze for 10 minutes, tap gently. Soak in alcohol overnight. Use soft brush to clear holes. Replace screen if severely damaged.
Unpleasant Odor
Solution: Complete deep clean with alcohol. Leave disassembled to air out overnight. Odors indicate buildup of old material.
Poor Grinding Performance
Solution: Clean thoroughly to remove buildup dulling teeth. Inspect for damaged teeth. May need replacement if teeth are worn down. If problems persist despite cleaning, review your grinding technique.
