Use dry, whole peppercorns and dry salt crystals (e.g., sea salt or kosher salt, medium-to-coarse size ~2-5 mm). Avoid wet or damp salts and extra-fine table salt. For a deeper dive, see our complete guide to choosing and using electric grinders.

Dry, hard, similar-size spices (e.g., allspice, coriander) and dry grains (e.g., rice) generally work well. Avoid oily, sticky, or soft items (e.g., sesame, flax, fresh herbs). Not designed for coffee beans, nuts, or seeds. Learn more about why freshly ground spices make a difference.

No. Coffee beans are too large and too oily for a pepper grinder and would damage the mechanism over time. Our ceramic burrs are designed for salt, pepper, dry whole spices, and dry grains. For coffee, use a dedicated coffee grinder.

Yes. Turn the adjustment dial/knob (usually on the top or base) toward coarse or fine until you get the grind you like.

Battery life depends on grind size and frequency but typically lasts for many cooking sessions (often weeks to months of home use) per charge. See how this compares in our electric vs. manual grinder comparison.

• Empty any remaining salt/pepper.
• Run briefly on coarse to clear the burrs, then power off.
• Brush the burrs and chamber. Wipe the exterior with a damp cloth.
• Do not submerge the motor housing or let water enter the charging port.

For a step-by-step walkthrough, see our complete cleaning guide.

Twist off the jar, pour in dry salt crystals or whole peppercorns, then reattach firmly. Avoid overfilling and leave a little headroom.

No. Hand rinse the spice chamber and brush the ceramic burrs. Do not submerge the motorized top or use the dishwasher.

About 1-2 hours with a standard 5V USB-C charger. An indicator light will show charging/charged status.

Ceramic burrs stay sharp far longer than steel ones and typically outlast the rest of the grinder. Under normal home use, you should never need to replace them. They are also non-reactive, so they will not rust or affect the flavor of your spices. Our complete grinder guide covers burr care in more detail.

Salt is naturally corrosive, but Vivosparks grinders use ceramic burrs and food-safe stainless steel specifically chosen to resist salt corrosion. The key is to use dry salt. Damp or wet salt accelerates corrosion and can jam the mechanism. Always store your grinder upright with the cap on to keep moisture out. See our cleaning guide for maintenance tips that extend the life of your grinder.

Focus on ceramic burrs (they stay sharp longer and resist corrosion), USB-C rechargeable power (no battery swaps), an LED near the grinding chute for visibility, and a tight-fitting hopper that keeps moisture out. A solid grinder should feel sturdy, adjust smoothly, and disassemble easily for cleaning. Read our in-depth expert guide for a full breakdown.

You can, but flavor will carry over between refills. If you switch, deep clean between refills and run a teaspoon of fresh peppercorns through to clear lingering flavors. A two-unit set is the simpler approach since each grinder stays dedicated. Our grinder set comes as a pair for exactly this reason.

• Charge for at least 15 minutes, then try again.
• Make sure parts are seated correctly and not cross-threaded.
• Try loosening the coarseness slightly. Over-tightening can stall the burrs.
• If it still will not run, contact support with a short video.

• Empty the chamber and check for oversized or damp crystals.
• Set to coarse, run briefly upside down to clear the burrs.
• Brush the burrs clean and refill with dry salt/pepper.

Empty the hopper, brush the burrs, and clear the chute with a wooden toothpick. Humidity can cake salt. Switch to dry crystals labeled "for grinders" and store refills in a sealed container. Our cleaning guide has more unclogging tips.

You will hear a normal motor hum while grinding. A squeal or harsh sound usually means the grind is set too fine or there is a jam. Loosen the dial and clear the chamber.

Yes. Food-contact parts use food-safe materials including industrial-grade alumina ceramic burrs and stainless steel where appropriate. Outer components use BPA-free materials. Always clean and fully dry parts before refilling.

No. Our grinders use industrial-grade alumina ceramic burrs, not plastic. Ceramic is harder than steel, corrosion-proof, FDA food-safe, and does not shed microplastics into your food. The grinding surfaces that contact your salt, pepper, and dry spices are ceramic.
