The present invention relates to a method for applying a protective layer to vessels or utensils used in the food industry, such as the milk and meat industries, wherein the vessels or utensils are contacted with an aqueous (natural) soap solution and then rinsed with water. The soap solution used is 2-10 ml, preferable 2-5 ml liquid soap per 100 l water, e.g. mains water. Furthermore, the relevant method is advantageously carried out at a temperature of the range of 10.degree.-40 .degree. C. By using a soap layer as protective layer, the use of disinfectants has become superfluous in the food industry so that the attendant problem of discharging or rendering harmless harmful disinfectants foreign to nature has also been solved.
A method for applying a protective layer to vessels or utensils used in the food industry, which protective layer prevents the adherence and/or growth of microorganisms which comprises the steps of contacting the vessels or utensils with an aqueous soap solution without disinfectant comprising from 2-10 ml of liquid soap per 100 l of water, said liquid soap comprising a potassium salt of a saturated or unsaturated C.sub.12-18 fatty acid and rinsing the vessels or utensils with water.
