Today's high hygiene standards and increased ecological awareness demand alternatives to the chlorine-alkaline foam cleaners, applied in heavily soiled areas. The newly introduced foam cleaning system uses oxidative cleaning components for the removal of extensive soilage without causing the waste water pollution associated with chlorinated alkaline cleaners. Besides the cleaning efficiency, the system also has a sanitizing effect. In combination with an optimum adapted application technology, development efforts resulted in a foam cleaning system, which decreases cleaning- as well as waste water-costs with economical product and consumption. The system offers additional benefits through a broad material compatibility and high safety standards for the operating staff.
