These grinder cleaning tablets are made from natural, biodegradable, and gluten-free ingredients, designed to clean burrs and casings by removing residue and coffee particles. They efficiently remove coffee oils and grind particles without the need to disassemble the grinder. However, they should not be used with integrated grinders in superautomatic machines (for which SuperGrindz is recommended). The tablets are formulated from all-natural, plant-based ingredients, free from phosphates, and all ingredients are food-safe. Available in a 430 g jar.
