Urnex Liquid Dezcal 1 L – Liquid descaler

Urnex Liquid Dezcal 1 L – liquid descaler for coffee equipment

Urnex Liquid Dezcal is a liquid descaling agent for compatible coffee and espresso machines, where limescale and mineral deposits can accumulate over time in parts that come into contact with hot water.

The product is ready for easy dosing and can be used, among other things, for descaling hot water tanks, boilers, and other compatible parts of coffee equipment.

The bottle contains 1 liter, making it suitable for those who descale regularly or have multiple machines.

Why should a coffee machine be descaled?

When water is heated repeatedly, minerals from the water can form limescale deposits inside the machine.

How quickly this happens depends, among other things, on:

• the hardness of the water
• how much the machine is used
• the construction of the machine
• whether a water filter is used
• the manufacturer's maintenance instructions

Regular descaling helps to remove these mineral deposits from the parts of the machine that the manufacturer allows to be descaled.

How to dose Liquid Dezcal in a coffee machine

For descaling directly in a compatible machine, Urnex specifies:

Approx. 30 ml of Liquid Dezcal per 1 liter of water tank capacity.

Example:

• 1-liter water tank → approx. 30 ml of Dezcal
• 1.5-liter water tank → approx. 45 ml of Dezcal
• 2-liter water tank → approx. 60 ml of Dezcal

Then always follow the coffee machine's own procedure for descaling and rinsing.

Machines may have different descaling programs, and therefore the machine manufacturer's instructions should always be followed along with the dosing instructions for Dezcal.

Descaling commercial boilers

For commercial descaling, where a boiler has been removed from the machine before treatment, Urnex specifies a solution of:

1 part Liquid Dezcal to 10 parts warm water.

This method is intended for professional maintenance of equipment where the boiler is descaled separately.

Do not use this mixture as a standard dosage directly in the coffee machine's water tank.

Descaling and cleaning are not the same

Descaling primarily removes mineral and limescale deposits from the machine's water system.

Coffee oils and coffee residues, on the other hand, require a cleaning agent developed specifically for that purpose.

If you have an espresso machine, there may therefore be a need for several types of maintenance:

• descaling of the water system
• cleaning of the brew group
• cleaning of the portafilter and filter baskets
• cleaning of the coffee grinder
• cleaning of the milk system

You can find the various products in our selection of cleaning agents for coffee equipment.

Can Liquid Dezcal be used in all coffee machines?

Not necessarily.

Always check the manufacturer's instructions for your specific machine before using an external descaling agent.

Some coffee machines have specific descaling programs or requirements for the products that may be used.

If the manufacturer specifies a certain procedure, this should always be followed.

How often should the coffee machine be descaled?

There is no single interval that suits all coffee machines.

The need depends especially on the water hardness and how much the machine is used.

A machine that is used a lot in an area with hard water will typically have a greater need for descaling than a machine that is used less or uses filtered/softer water.

Therefore, follow the machine manufacturer's recommended maintenance interval first and foremost.

A water filter can reduce the limescale load

A compatible water filter can, in some machines, reduce the amount of minerals that end up in the machine's water system.

However, this does not necessarily mean that descaling will never be necessary.

Always follow the machine manufacturer's recommendations for both water filters and descaling.

Always rinse thoroughly after descaling

After descaling, the machine must be rinsed thoroughly with clean water according to the manufacturer's instructions.

This ensures that the descaling solution is removed from the machine's water system before you brew coffee again.
