How to Clean a Pepper Mill

Why Pepper Mills Need Regular Cleaning

Pepper mills accumulate pepper dust, oils, and residue in the grinding mechanism over time. Old pepper oils go rancid and affect the flavor of freshly ground pepper. The grinding burrs can also clog with fine pepper dust, reducing grinding efficiency. Regular cleaning keeps your pepper mill grinding smoothly and producing fresh-tasting pepper.

What You'll Need

• Small brush or pastry brush
• Dry cloth or paper towels
• Microfiber cloth
• Mild dish soap (for the exterior only)
• Warm water (minimal)

The Most Important Rule: Keep It Dry

Never submerge a pepper mill in water or run it under the tap. Moisture causes peppercorns to swell and jam the mechanism, and can damage wooden mills. All interior cleaning must be done dry.

Step-by-Step Cleaning

1. Empty all remaining peppercorns from the mill
2. Use a small brush or pastry brush to sweep out pepper dust and residue from the interior chamber
3. Brush the grinding burrs thoroughly — this is where most buildup occurs
4. Wipe the interior with a dry cloth or paper towel
5. Grind a small amount of dry white rice through the mill — the rice absorbs oils and cleans the burrs as it grinds
6. Discard the ground rice
7. Brush out any remaining rice dust
8. Refill with fresh peppercorns

Cleaning the Exterior

For the Home EC stainless steel pepper grinder and similar stainless steel mills, wipe the exterior with a damp cloth and mild dish soap. Dry immediately with a microfiber cloth. For wooden mills, wipe with a barely damp cloth and dry immediately — never use wet cloths on wood.

Cleaning the Glass Body

If your pepper mill has a glass body, wipe with a damp cloth and dry with a microfiber cloth to prevent water spots.

How Often to Clean

• Light cleaning (brush out dust): every 1–2 months
• Rice cleaning of burrs: every 3–6 months
• Full empty and clean: when refilling with fresh peppercorns

Final Thoughts

Pepper mill cleaning is quick and dry — a brush and the rice method handle everything. Never use water inside the mill. Regular cleaning keeps the burrs sharp, the mechanism smooth, and your pepper tasting fresh.
