The invention relates to a method for cleaning surfaces of polyolefin-based materials soiled with food, particularly dairy products. More specifically, the invention relates to a method for cleaning materials based on one or more halogenated or non-halogenated polyolefins and soiled with food, particularly dairy products, which method is particularly safe for the environment, but also for the soiled polyolefin-based material with minimal wear and tear. According to the invention, the soiled material is brought into contact with an aqueous composition based on alkane sulfonic acids having between 1 and 4 carbon atoms.
La présente invention concerne un procédé de nettoyage de matériaux à base de polyoléfine(s) halogénées(s) ou non souillés par des denrées alimentaires, notamment des produits laitiers, particulièrement respectueux pour l'environnement mais aussi pour le matériel souillé à base de polyoléfine dont l'usure et la dégradation sont minimales. Ce procédé consiste en la mise en contact du matériel souillé avec une composition aqueuse à base d'acide(s) alcane sulfonique(s) ayant de 1 à 4 atomes de carbone.
