A process is described wherein a surface, for example the exterior surface of a vehicle, is contacted with a cleaning composition capable of rendering the surface treated hydrophilic and then rinsed with purified rinse water. Preferably the process also involves a pre-wetting step, wherein the surface is rinsed with water prior to being contacted with the cleaning composition, and/or an additional rinsing step, wherein the surface is rinsed with unpurified water prior to rinsing with the purified rinse water.

L'invention concerne un procédé dans lequel une surface, la surface extérieure d'un véhicule, par exemple, est mise en contact avec une composition de nettoyage capable de rendre la surface traitée hydrophile, puis rincée avec de l'eau de rinçage purifiée. Ce procédé comprend également, de préférence, une étape de pré-mouillage, dans laquelle la surface est rincée avec de l'eau avant d'être mise en contact avec la composition de nettoyage, et/ou une étape de rinçage supplémentaire, dans laquelle la surface est rincée avec de l'eau non purifiée avant le rinçage à l'eau de rinçage purifiée.
