- Zuecos de pantalla (no colección de kief)
- Hilos palo y tira
- eventualmente se apodera de
con qué frecuencia limpiar
Limpieza rápida del cepillo:
- Después de cada 5-10 usos
- toma 2 minutos
- Evita la acumulación pesada
Limpieza profunda (congelación + alcohol):
- Usuarios diarios: Cada 2-4 semanas
- Usuarios semanales: Cada 2-3 meses
- Usuarios ocasionales: Cada 4-6 meses
Firma que necesita limpieza: Cuando el giro se vuelve difícil o la pantalla se ve obstruida
lo que necesitas
Para limpieza básica:
- cepillo de dientes o cepillo rígido
- palillo o póquer
- toallas de papel
Para limpieza profunda:
- 90%+ alcohol isopropílico
- Tarro o recipiente (vaso)
- Bolsas de congelador
- Brush
- Hot water
- Towels
Optional:
- Q-Tips para trabajos detallados
- Limpiadores de tuberías para roscas
Paso a paso: Método de limpieza profunda
Paso 1: desmontar completamente
Desmontar cada pieza:
- Cámara de molienda superior
- Cámara inferior (si es de 3 o 4 piezas)
- Pantalla (si está presente)
- Receptor de Kief (si 4 piezas)
Diseñar todas las piezas - easier to track and clean individually
Paso 2: Guarda tu kief primero
Paso crítico:
- Raspa cuidadosamente el kief de la cámara de captura
- Ahorre en un contenedor separado
- ¡No pierdas tricomas potentes!
Usa raspador de kief that came with grinder or small spoon
Paso 3: Congela durante 20-30 minutos
Por qué funciona la congelación:
- El frío hace que la resina sea frágil (no pegajosa)
- Los trozos se rompen fácilmente
- Reduce el lavado necesario
How:
- Ponga todas las piezas de molinillo en una bolsa para congelar
- Congelar 20-30 minutos (no más - innecesario)
- La flor de cannabis puede permanecer a temperatura ambiente
Paso 4: Cepille y grite la resina congelada
Retire del congelador inmediatamente:
Brushing:
- Use cepillo de dientes rígido en los dientes
- cámaras de fregado
- Cepille la pantalla suavemente (no dañe)
Tapping:
- Golpee las piezas sobre la basura/papel
- Los trozos de resina congelada se caen
- Mucho más fácil que raspar la resina pegajosa
Esto elimina el 60-70% de la acumulación without solvents
Paso 5: Remojo de alcohol isopropílico
Elección de alcohol:
- 90-99% isopropilo: Mejor, más rápido
- 70%: Funciona pero más lento
- Below 70%: No usar (demasiada agua)
Soaking:
1. Coloque todas las piezas en un frasco/contenedor
2. Cubra completamente con alcohol isopropílico
3. Remoje 20-30 minutos mínimo
4. Acumulación obstinada: remojo 1-2 horas
que pasa: El alcohol disuelve la resina/el residuo de THC
Paso 6: Frote bajo el agua caliente
Después de remojar:
1. quitar las piezas del alcohol
2. Frote cada pieza con cepillo bajo agua corriente caliente
3. Presta atención a:
- Between teeth
- Threads
- Screen holes
- Corners and crevices
La resina debe enjuagarse fácilmente after alcohol soak
Step 7: Dry Completely
CRITICAL - must be 100% dry:
Drying options:
- Towel dry thoroughly
- Air dry for 30 minutes
- Use hair dryer on low (careful - hot metal)
Why complete drying matters:
- Moisture + cheap metal = rust
- Alcohol residue tastes bad
- Wet grinder gums up immediately
Step 8: Reassemble
Once fully dry:
- Put grinder back together
- Should turn smoothly
- Looks brand new
- Grinds like new
Test: Load small amount and grind - should be effortless
Quick Cleaning Method (5 Minutes)
When you don't have time for deep clean:
1. Disassemble grinder
2. Brush out loose material with toothbrush
3. Use toothpick for stuck bits
4. Wipe down with damp cloth
5. Dry and reassemble
This maintains grinder between deep cleans
Alternative Method: Boiling Water
For food-safe grinders only (quality metal):
1. Boil water in pot
2. Drop grinder pieces in (5-10 minutes)
3. Remove and brush under cold water
4. Dry thoroughly
Pros: No chemicals, effective
Cons: Can damage cheap grinders, hot to handle, can strip anodization
Screen Cleaning (4-Piece Grinders)
The screen clogs first:
Prevention:
- Brush screen after every few grinds
- Tap grinder to knock kief through
- Don't press cannabis into screen
Deep clean clogged screen:
1. Freeze grinder
2. Brush frozen screen vigorously
3. Use toothpick for stubborn holes
4. Alcohol soak if still clogged
Nuclear option: Replace screen (some grinders have replaceable screens)
Common Cleaning Mistakes
Mistake: Using Water Only
Problem: Water doesn't dissolve resin (oil-based)
Solution: Must use alcohol or boiling water. Cold/warm water just makes mess.
Mistake: Not Drying Completely
Problem: Rust, immediate re-gunking
Solution: Dry thoroughly, let air dry extra 15 minutes to be safe
Mistake: Losing Kief Down Drain
Problem: Rinsing kief away while cleaning
Solution: Save kief FIRST before any cleaning
Mistake: Using Soap
Problem: Soap residue tastes terrible, hard to rinse completely
Solution: Alcohol only (or boiling water). Never use soap.
Maintenance Tips
Tip 1: Don't Over-Pack
Grinding too much at once = faster buildup
Tip 2: Brush After Every 5-10 Grinds
2-minute maintenance prevents heavy buildup
Tip 3: Store Empty
Don't leave ground flower in grinder overnight - creates sticky mess
Tip 4: Quality Matters
Good grinders (Santa Cruz, Space Case) have anodized finishes that resist sticking
Tip 5: Coin Trick
Add small coin to collection chamber - knocks kief through screen during use
What About the Resin?
Grinder resin contains:
- THC (yes)
- Plant material
- Metal particles
- Dust and debris
Should you save it?
Arguments for:
- Contains THC
- Can be smoked in desperate times
- Some people collect it
Arguments against:
- Contains metal particles (unhealthy)
- Harsh, tastes bad
- Kief from kief catcher is way better
- Not worth health risk
Recommendation: Discard resin, save kief
Cleaning Different Grinder Materials
Aluminum Grinders (Most Common):
Safe methods:
- Freezing ✅
- Isopropyl alcohol ✅
- Boiling water ✅ (quality ones)
- Brushing ✅
Avoid: Steel wool (scratches), harsh chemicals
Titanium Grinders:
Very durable - all methods safe
Anodized Grinders:
Be gentle:
- Avoid abrasives (scratches protective coating)
- Boiling can strip anodization
- Stick to freezing + alcohol
Troubleshooting
Problem: Threads Stripped/Cross-Threaded
Cause: Forcing grinder when dirty/misaligned
Fix: Clean threads thoroughly with brush, align carefully when reassembling
Problem: Screen Permanently Clogged
Cause: Years of buildup, poor quality screen
Solution:
- Extended alcohol soak (overnight)
- Ultrasonic cleaner (if available)
- Replace screen
- Buy new grinder
Problem: Grinder Still Sticky After Cleaning
Causes:
- Didn't dry completely (alcohol residue)
- Low-quality alcohol (too much water)
- Cheap grinder (poor coating)
Solution: Re-clean with 90%+ alcohol, dry longer, consider upgrade
How to Clean Specific Grinder Parts
Teeth:
Most important - where grinding happens
- Brush between every tooth
- Use toothpick for crevices
- Alcohol soak crucial
Threads:
Easy to neglect, critical for function
- Brush threads carefully
- Use Q-tip for deep threads
- Clean buildup causes seizing
Screen:
Most delicate part
- Brush gently (don't damage holes)
- Alcohol soak helps most
- Careful with toothpick (don't tear screen)
Kief Catcher:
Easiest to clean (smooth chamber)
- Save kief first!
- Simple wipe usually enough
- Alcohol for stuck-on kief
This guide is for educational purposes. Cannabis laws vary by jurisdiction.
Step 1: Disassemble completely

Take apart all pieces - top, bottom, screen (if 4-piece), kief catcher. Separate every component for thorough cleaning.
Step 2: Save your kief

Carefully collect and save any kief from catcher chamber before cleaning. Don't waste potent trichomes down the drain!
Step 3: Freeze for 20 minutes

Place all grinder pieces in freezer for 20-30 minutes. Cold makes resin brittle and easier to remove.
Step 4: Brush and tap

Remove from freezer. Use toothbrush or stiff brush to scrub teeth and chambers. Tap pieces to knock out frozen resin chunks.
Step 5: Isopropyl alcohol soak

Submerge all pieces in 90%+ isopropyl alcohol. Let soak 20-30 minutes. Stubborn buildup may need 1-2 hours.
Step 6: Scrub and rinse

Remove from alcohol. Scrub with brush under hot water. All resin should come off easily now. Clean screen carefully.
Step 7: Dry completely

Dry all pieces thoroughly with towel or air dry. Any moisture will cause rust on cheaper grinders. Must be 100% dry.
Step 8: Reassemble

Put grinder back together once fully dry. Should turn smoothly and look brand new.
