Coffee Machine Cleaners & Cleaning Tablets: The Complete Urnex UK Guide

Keep your coffee tasting fresh, your machine running efficiently, and your customers coming back.

Whether you’re a barista, a business, or a coffee supplier, the right cleaner makes all the difference.


Why Cleaning Matters

Every cup of coffee leaves something behind — oils, residue, milk proteins, or mineral deposits.
Over time, these build up inside your machine, affecting taste, temperature, and reliability.

Here’s what regular cleaning helps prevent:

  • Oily residue that causes bitterness and blockages

  • Milk build-up that affects frothing and hygiene

  • Limescale that reduces efficiency and damages boilers

Using a proper coffee machine cleaner or cleaning tablet keeps your equipment in top condition — protecting your investment and ensuring every brew tastes as good as the first.
