A rub test to prove hygienically clean surfaces.
Validated and tried and tested.
For quick recognition of whether not only food residues have been carefully removed in the course of cleaning and disinfection,
but also thoroughly and properly rinsed.
The Clean Card detects all protein-containing soiling such as e.g. allergen proteins and surfactants from cleaning agent or disinfectant residues on optically clean surfaces - important especially for all objects and surfaces that come into contact with food, but also in other areas
where there should be no more residues on clean surfaces.
