Use Durgol Universal Descaler to remove limescale from your espresso machine and kettle without damaging materials. Follow these safe steps and spot the common mistakes.
Quick answer
Use Durgol Universal Descaler diluted 1:1 with tap water, run it through your machine, then rinse twice with clean water. Descale every 2–3 months if your water is hard, or when you notice reduced flow or white scale.
Why dilution and rinsing matter more than soaking
Durgol Universal Descaler is formulated to be gentle on materials and food-safe when used as directed. The instructions specify mixing 150 ml of descaler with the same amount of tap water before running it through the machine. Using it undiluted may be too aggressive for some components and wastes product.
Rinsing twice with tap water is not optional. Residual descaler can affect taste and, over time, harm seals. If you skip the second rinse, your next espresso may taste sour or soapy.
When to descale: frequency depends on water hardness
There is no single schedule that fits every household. As a practical rule, descale every 2–3 months if you use hard tap water, or every 4–6 months if your water is soft. If you have a water softener or use filtered water, you can stretch the interval, but still descale at least twice a year.
Pay attention to signals: slower water flow, unusual noises during brewing, or visible white crust around the steam wand or shower screen. These indicate scale buildup and mean it is time to descale, regardless of the calendar.
What Durgol Universal Descaler can and cannot do
This descaler is suitable for coffee machines, kettles, and other household items that need limescale removal. It is not a cleaning agent for coffee oils or milk residue—use a dedicated cleaner for those tasks. Also, do not use it on marble, enamel, or any surface where acid-based products are not recommended. Always check your machine manual for any specific warnings.
Safe descaling steps with Durgol Universal Descaler
- Prepare the machine and solution: Empty the water tank and remove any water filter. Pour 150 ml of Durgol Universal Descaler into the tank, then add 150 ml of tap water. Swirl gently to mix. Never use undiluted descaler; the 1:1 ratio is required for safe cleaning.
- Run the solution through: Place a large container under the group head and steam wand. Start the descaling cycle if your machine has one, or run the pump in short bursts until the tank is empty. Let the solution sit in the boiler for 5–10 minutes before flushing, but do not exceed 15 minutes. Do not let the solution sit for hours; prolonged contact can damage seals.
- Rinse twice with clean water: Fill the tank with fresh tap water and run it all through the machine. Repeat with a second full tank. This removes all traces of descaler. Skipping the second rinse risks leaving acidic residue that affects taste.
- Reassemble and test: Reinstall the water filter if you use one. Pull a shot of espresso and taste it; if it tastes off, run another rinse cycle. Wipe the exterior with a damp cloth. A sour or chemical taste means more rinsing is needed.
