Method of cleaning a hard surface (e.g. floor) in order to remove a complex soil comprises contacting the surface with a first cleaning composition which has a non-neutral pH and then contacting the surface with a second cleaning composition which has a complementary non-neutral pH to that of the first cleaning composition. (The term "complementary" refers to acidic or alkaline as appropriate). Mechanical force may be employed during the application of either or both of the cleaning compositions.
Cette invention concerne un procédé de nettoyage d'une surface dure (d'un sol, par exemple) et d'élimination de salissures tenaces, lequel procédé comprend plusieurs étapes. La surface est tout d'abord mise en contact avec une première composition nettoyante ayant un pH non neutre, puis avec une seconde composition nettoyante ayant un pH non neutre complémentaire de celui de la première composition nettoyante, le terme "complémentaire" signifiant acide ou alcalin selon le cas. Une force mécanique peut être employée lors de l'application de l'une ou des deux compositions nettoyantes.
