The Durgol Swiss Steamer is a specialized descaling agent designed specifically for the maintenance of steam ovens and steam cookers. This 500 ml solution effectively removes limescale from water tanks, boiler evaporators, and steam heaters, ensuring your appliances continue to operate efficiently. Formulated with a blend of phosphoric and hydrochloric acid in an aqueous base, the liquid is food-safe and engineered to leave no residue behind. It also prevents foam formation during the cleaning process, which makes the descaling task more straightforward. With a shelf life of three years from the date of manufacture, you can keep it on hand for regular maintenance to protect your equipment from mineral buildup.
