Keeping your coffee equipment clean is super important, not only for its longevity, but also for the flavour of your coffee. Urnex Cleancaf is a product formulated specifically for the home or small office coffee drinker. It removes coffee oil & residue in conventional filter machines, or any other small coffee equipment. The powder includes blue dye to ensure that when you run it through your machine, you know when it has all been rinsed out and, unlike the vinegar that many people will use, it doesn’t leave behind any unpleasant smells!
