How to Clean a Grinder Properly (Without Damaging It)

1️⃣ When Should You Clean a Grinder?

Signs your grinder needs cleaning:

• 
  Stiff rotation
  
• 
  Uneven grind
  
• 
  Visible build-up
  
• 
  Difficulty opening chambers
  

Ignoring build-up causes long-term wear.

2️⃣ Routine Cleaning (Quick Maintenance)

For regular upkeep:

• 
  Disassemble the grinder
  
• 
  Tap out loose debris
  
• 
  Use a soft brush to clean teeth and threads
  

This prevents heavy build-up.

3️⃣ Deep Cleaning Metal Grinders

Metal grinders can handle deeper cleaning.

Steps:

• 
  Disassemble completely
  
• 
  Soak metal parts in isopropyl alcohol
  
• 
  Gently brush teeth and threads
  
• 
  Rinse with warm water
  
• 
  Dry thoroughly before reassembly
  

Never reassemble while damp.

4️⃣ Cleaning Acrylic Grinders Safely

Acrylic grinders are more delicate.

Safe method:

• 
  Use warm (not hot) water
  
• 
  Mild soap if needed
  
• 
  Soft brush only
  
• 
  Air-dry completely
  

Avoid alcohol or harsh chemicals.

5️⃣ Cleaning Screens & Chambers

Screens should be brushed gently. Avoid pushing debris through forcefully, which can damage mesh.

6️⃣ What NOT to Do

Avoid:

• 
  Boiling water
  
• 
  Metal tools or knives
  
• 
  Excessive force
  
• 
  Strong solvents on acrylic
  

These shorten grinder lifespan.

7️⃣ Preventing Future Build-Up

• 
  Clean lightly but regularly
  
• 
  Avoid overfilling
  
• 
  Store grinders clean and dry
  

Prevention is easier than deep cleaning.

🔚 Final Thoughts

Cleaning a grinder properly improves performance, extends lifespan and makes rolling more consistent. Gentle, regular maintenance keeps grinders sharp, smooth and reliable without risk of damage.

A clean grinder is a better grinder.
