The surface of the evaporator is treated, without a preliminary stage of surface conversion, with a liquid comprising one or more substances capable of conferring, on the resulting coat, properties of adherence to the substrate and film-forming and corrosion-inhibiting and hydrophilic properties and one or more substances capable of conferring, on said coat, antimicrobial properties, the ratio by weight of the substances capable of conferring adherence properties and film-forming, corrosion-inhibiting and hydrophilic properties to the substances capable of conferring antimicrobial properties being less than or equal to 2/100. The coat thus formed is insoluble in water and does not exhibit an odor. Application to air conditioners for vehicles.
