This is one of our most popular coffee grinder cleaners and is the world's first and only product designed specifically for cleaning coffee grinders. Launched in June of 2005, GRINDZ is an all-natural, food-safe, gluten-free, organic and flavor neutral combination presented in coffee bean-shaped tablets. Grindz quickly and effectively removes stale coffee residue and flavored coffee odors from the internal burrs and casings of coffee grinders. It requires no grinder disassembly: simply run the product through the machine just like coffee.
