How does WoldoClean clear 2-in-1 liquid descaler work?
The term 2-in-1 cleaning and descaling refers to the care of the internal water circuit in coffee machines and other suitable appliances. The concentrated formulation contains sulfamic acid and citric acid, which loosen and remove limescale and other mineral deposits that gradually build up during regular use.
Product information for the clear 750 ml version also specifically lists a corrosion inhibitor in the formulation. It helps protect delicate internal components and pipework during descaling. The clear solution does not have a colour indicator, so its remaining effectiveness cannot be assessed by watching for a change in colour.
Descaler serves a different purpose from coffee machine cleaning tablets. It is not designed to remove coffee oils or greasy deposits from the brew unit. For thorough machine care, descaling the water circuit and cleaning the brewing system are separate but complementary maintenance steps.
What is the difference between the clear and pink-red WoldoClean descalers?
Both products are concentrated 2-in-1 descalers designed to clean and descale the internal water circuit. Product information for the clear 750 ml version specifically lists a corrosion inhibitor. The pink-red version is distinguished by a practical colour indicator that helps show whether the solution still has a descaling effect.
| Feature | Clear descaler without colour indicator | Pink-red descaler with colour indicator |
|---|---|---|
| 2-in-1 cleaning and descaling | Yes | Yes |
| Colour indicator | No – the clear solution does not change colour to show when its effect has been exhausted | Yes – a colour change shows when the descaling effect has been exhausted |
| Key distinguishing feature | The product information specifically lists a corrosion inhibitor | The colour indicator provides a visual guide to the remaining descaling effect |
| Available sizes | 750 ml | 750 ml and 5 litres |
| Which one should you choose? | Choose this version if you prefer a clear solution without a colour indicator | Choose this version if you want a visible indication of the remaining effect or need the 5-litre size |
Which version is right for you? Choose the clear descaler if you prefer a solution without a colour indicator and a version whose product information specifically lists a corrosion inhibitor. For a visible colour-change indicator, or if you need the larger 5-litre size, view the pink-red WoldoClean liquid descaler with colour indicator.
Important: the term 2-in-1 refers to cleaning and descaling the internal water circuit by loosening mineral build-up and removing limescale. Neither version replaces coffee machine cleaning tablets designed to remove coffee oils and greasy deposits from the brew unit.
What role does the corrosion inhibitor play during descaling?
The corrosion inhibitor is included in the formulation of the clear 750 ml version and helps protect delicate components and internal pipework during descaling. This does not mean that the product is suitable for every material or appliance. Always follow the recommended dilution ratio and the instructions supplied by the appliance manufacturer.
Which coffee machines and appliances can it be used with?
WoldoClean is primarily intended for the regular care of coffee machines. It is suitable for bean-to-cup, manual espresso, capsule and filter coffee machines.

- The descaler manufacturer recommends a contact time of approximately 5 to 10 minutes, unless the appliance instructions specify a different procedure.
- Once descaling is complete, rinse the water tank thoroughly.
- Run one or two full tanks of clean water through the machine, or follow the rinsing programme recommended by the manufacturer.
Dilution and application instructions may differ for other appliances. Always follow the directions provided by the manufacturer of the appliance you are cleaning.
How much does one descaling cycle cost?
Cost per descaling cycle: The 750 ml bottle contains six 125 ml doses. At the current price of €10.29, one descaling cycle costs approximately €1.72.
Coffee machine descaler or cleaning tablets?
Liquid descaler and cleaning tablets tackle two different types of build-up:
- Liquid descaler: removes limescale and mineral deposits from the internal water circuit.
- Cleaning tablets: remove coffee oils, greasy deposits and organic residue from the brew unit.
For thorough bean-to-cup coffee machine care, the two cleaning processes complement one another. You may also wish to view our phosphate-free coffee machine cleaning tablets.

Frequently asked questions about WoldoClean clear 2-in-1 descaler
What is the difference between the clear and pink-red WoldoClean descalers?
Both versions are 2-in-1 descalers. The clear version does not have a colour indicator, and its product information specifically lists a corrosion inhibitor. The pink-red version uses a colour change as a visual guide and is available in both 750 ml and 5-litre sizes.
Does the clear descaler change colour during use?
No. The clear version does not have a colour indicator and therefore does not change colour to indicate whether the solution is still effective.
What does the corrosion inhibitor do?
The corrosion inhibitor helps protect delicate internal components and pipework during descaling. Always use the recommended dilution ratio and follow the instructions supplied by the appliance manufacturer.
What does 2-in-1 cleaning and descaling mean?
It refers to loosening mineral build-up and removing limescale from the internal water circuit in a single maintenance cycle. The product does not replace cleaning tablets designed to remove coffee oils from the brewing system.
Can the descaler be used in coffee machines and other household appliances?
Yes. It is suitable for common types of coffee machine and, subject to the manufacturer’s instructions, may also be used in electric kettles, steam ovens, steam cleaners, steam ironing stations and other suitable appliances. Always check the instructions for the particular appliance before use.
How much descaler should you use for one cycle?
For one standard cycle, use 125 ml of descaler with 500 ml of water, unless the appliance manufacturer specifies a different procedure.
How often should you descale a coffee machine?
The required frequency depends on the hardness of your water, the number of drinks you prepare and the machine’s settings. Follow the machine’s descaling alert or the interval specified by its manufacturer.
Does clear liquid descaler also remove coffee oils?
No. The descaler is intended to remove limescale and mineral deposits. Coffee oils and greasy deposits in the brew unit should be removed using dedicated coffee machine cleaning tablets.

All-purpose has its limits. WoldoClean goes beyond everyday cleaning tablets with dedicated products for coffee machines, robotic mops, ovens and drains. Coffee oils and limescale require different treatments. So do routine drain maintenance and stubborn blockages.
Inside the WoldoClean range
- Cleaning, in tablet form – 40 all-purpose tablets make up to 200 litres of cleaning solution, depending on dilution. Separate dissolvable toilet tablets are formulated for ceramic toilet bowls.
- Two sides of coffee machine care – phosphate-free tablets remove coffee oils from compatible brewing units, while the liquid descaler targets mineral deposits in the water system.
- Floors and tougher surfaces – a concentrated cleaner for compatible robotic mops, diluted at 15 ml per 300 ml of water. For baked-on cooking grease, there's a separate oven and grill cleaner supplied with an application brush.
- Drain care, two ways – an enzyme-based gel for regular maintenance and a more intensive Power cleaner for blocked household drains.
