Urnex Grindz Coffee Grinder Cleaning Tablets - 430g (15.2oz)
Clean Your Grinder Without Taking It Apart
Urnex Grindz is the world's first and only cleaning product designed specifically for coffee grinders. These innovative coffee bean-shaped tablets run through your grinder just like regular beans—removing stale oils, residue, and odors without any disassembly required.
The Problem with Dirty Grinders: Coffee oils build up on burrs and casings over time, turning rancid and making fresh beans taste stale or bitter. Switching between regular, decaf, and flavored beans causes flavor contamination. Traditional cleaning requires complete disassembly—time-consuming and risky.
The Grindz Solution: Simply run these tablets through your grinder like coffee beans. They gently dislodge particles and absorb oils, leaving your grinder fresh and ready for pure-tasting coffee. All-natural, food-safe, and completely effective.

What It Removes
Coffee Oils: Oils from coffee beans accumulate on burrs and turn rancid, causing bitter, off-flavors in fresh coffee.
Stale Residue: Old coffee particles stick to burrs and casings, contaminating every batch with stale taste.
Flavored Coffee Odors: Switching from hazelnut to regular? Vanilla to espresso? Grindz removes lingering flavors completely.
Fine Particles: Grindz dislodges stuck particles that regular brushing can't reach, preventing jamming and maintaining consistent grind size.

Why Grinder Cleaning Matters
Better Tasting Coffee: Rancid oils and stale residue ruin the flavor of fresh beans. A clean grinder means pure coffee taste every time.
Consistent Grind Size: Buildup on burrs affects grind consistency, leading to uneven extraction and poor-tasting espresso or coffee.
Extended Grinder Life: Regular cleaning prevents jamming, reduces wear on burrs, and keeps your grinder running smoothly for years.
No Flavor Contamination: Switch confidently between regular, decaf, and flavored beans without worrying about flavor transfer.
