Learn how to descale your steam generator iron safely and effectively. Our step-by-step guide helps you remove limescale and keep your iron performing at its best.
Quick answer
Descale your steam generator iron every 1-2 months using a dedicated descaler to prevent limescale buildup, maintain steam performance, and extend the life of your appliance.
Why descaling matters for your steam generator iron
Limescale from hard water can clog the internal steam channels and reduce steam output, leaving your clothes less wrinkle-free. Regular descaling keeps the soleplate clean and the steam flow strong.
Using a dedicated descaler is safer than vinegar or lemon juice, which can damage the internal seals and void your warranty. A purpose-made product is formulated to dissolve scale without harming the appliance.
Step-by-step descaling process
- Prepare the iron and descaler solution: Unplug your steam generator iron and let it cool completely. Remove the water tank and empty any remaining water. Mix the descaler according to the instructions on the bottle (usually a 1:1 ratio with water). Never descale a hot iron – the solution can boil and cause burns.
- Fill the water tank with the solution: Pour the mixed descaler solution into the water tank. Replace the tank securely on the iron. Do not overfill – leave some space for the solution to move during the process.
- Run the descaling cycle: Plug in the iron and set it to the highest steam setting. Allow the iron to heat up, then press the steam button repeatedly over a sink or old towel until the tank is empty. This flushes the solution through the internal steam system. Work in a well-ventilated area – the steam may carry mineral particles.
- Rinse the water tank thoroughly: Remove the tank and rinse it with clean water. Fill it with fresh water, replace it, and run a full steam cycle to flush out any remaining descaler residue. Repeat the rinse cycle if you see any white residue on the soleplate.
- Wipe the soleplate and store: Once the iron has cooled, wipe the soleplate with a damp cloth to remove any loosened scale. Empty the water tank and store the iron upright in a dry place. Regular descaling every 1-2 months prevents scale from hardening and becoming harder to remove.
Recommended product for descaling
- Multi Purpose Descaler: Our descaler is odourless, safe for use in kettles and coffee machines, and just one application will destroy the scale that could shorten the life of your appliance. This odourless formula is ideal for steam generator irons because it won't leave a lingering smell on your clothes, and one application effectively removes scale to restore steam performance.
