Operating Instructions
Durgol Universal Descaler is suitable for various household items. Always refer to the appliance manufacturer's instructions for descaling, if available.
General Descaling Process:
- Dilution: For light limescale, dilute Durgol Universal with water (e.g., 1:1 ratio). For heavy limescale, use undiluted.
- Application: Apply the descaler to the affected area or fill the appliance with the solution.
- Soaking Time: Allow the descaler to work for a few minutes. Do not exceed 30 minutes to prevent potential damage to sensitive materials.
- Rinsing: Thoroughly rinse the item or appliance with clean water multiple times to remove all descaler residue.
- Drying: Dry the item completely before use.
Specific Applications:
Coffee Machines (Drip Coffee Makers):

- Pour 1-2 cups (approx. 250-500ml) of Durgol Universal Descaler into the water tank.
- Add an equal amount of water if recommended by the coffee machine manufacturer, or if the limescale buildup is moderate.
- Start the brewing cycle as if making coffee, but without coffee grounds.
- Allow the solution to run through the machine completely.
- After descaling, run 2-3 full cycles with clean water to thoroughly rinse the machine.
Kettles:

- Fill the kettle with enough Durgol Universal Descaler to cover the limescale deposits (e.g., 1-2 cups).
- Do not heat the descaler. Allow it to sit for a few minutes until the limescale dissolves.
- Pour out the solution and rinse the kettle thoroughly with cold water at least three times.
Faucets and Shower Heads:

- For removable parts like shower heads, immerse them in a solution of Durgol Universal Descaler and water.
- For fixed faucets, apply the descaler directly using a cloth or spray bottle.
- Allow to act for a few minutes, then scrub gently if necessary.
- Rinse thoroughly with clean water.
Maintenance
Regular descaling helps maintain the efficiency and lifespan of your appliances. The frequency of descaling depends on the hardness of your water and how often you use the appliance.
- For areas with hard water, descaling every 1-2 months is recommended.
- For areas with soft water, descaling every 3-4 months may suffice.
- Always follow the specific recommendations of your appliance manufacturer.
Troubleshooting
If limescale persists after the first application:
- Heavy Limescale: Repeat the descaling process, possibly using undiluted Durgol Universal Descaler and allowing a slightly longer (but still limited) soaking time.
- Incomplete Rinsing: Ensure thorough rinsing with clean water after descaling to prevent any residue or taste.
- Appliance Malfunction: If the appliance does not function correctly after descaling, consult the appliance's own instruction manual or contact the appliance manufacturer's support.
