In our offer you will only find detergents of reputable manufacturers which have been proven and used for years by our customers. Among them, the products of the Austrian company THONHAUSER (with the colour change technology) deserve a special attention. The substances used in them react to microbiological impurities present in the cleaned beverage system by changing the color of the cleaning solution from originally purple to green. The installation is cleaned until the colour of the cleaning solution returns to its original purple color.
