CF425CMD Aktivo Coffee Machine Descaler Liquid 425ml, Limescale Remover for Home Coffee Machines

CF425CMD is a 425ml bottle of liquid descaler for coffee machines, from the Aktivo cleaning range. Hard water leaves limescale in the boiler, thermoblock and water lines of a coffee machine, and a regular descale keeps water moving at the right temperature and flow. The dose and method are set out on the label, so follow those together with the descaling steps in your coffee machine manual.

Signs your coffee machine needs descaling

Scale forms wherever water is heated. In a coffee machine that means the boiler or thermoblock, the pump lines and the group head or brew unit. As the layer thickens, the machine takes longer to heat, the coffee comes out cooler or weaker, the flow slows to a dribble and the steam wand loses its punch. Many machines also show a descale light or message after a set number of cycles. Descaling on schedule, and more often in hard water areas, costs far less than replacing a blocked valve or a failed heating element later.

How to descale with a liquid descaler

Read your coffee machine manual first, as some machines have a dedicated descale program and some makers specify their own product. Mix the descaler as the label directs, run it through the water lines and steam wand, then rinse with several full tanks of fresh water so no taste carries into the next coffee. Store the bottle out of reach of children.

Questions about this part

Will this work in my coffee machine?

It is a general liquid descaler for coffee machines. Check your machine manual for any descaler the maker requires or advises against, then follow the label on the bottle for the dose and method.

How often should I descale?

Follow the descale light on your machine or the interval in its manual. Machines used every day in hard water areas generally need descaling more often than those running on soft water.
