The present invention provides an apparatus for surface cleaning, in which a first liquid, which includes an oxidizing agent, and a second liquid, which includes a builder or a chelating agent, are initially maintained separately. The apparatus is constructed to facilitate delivery of these two liquids such that they are combined to form an admixture during delivery to a surface to be treated. Either or both of the first and second liquids include a pH-adjusting agent, which is present in an amount such that when the liquids are so delivered, the resulting admixture is maintained at a pH sufficient for cleaning efficacy and stability of the oxidizing agent. The present invention also provides a composition produced by a process of maintaining the two above- mentioned liquids separately and forming an admixture thereof during delivery to a surface to be treated.
Cette invention a trait à un appareil de nettoyage de surfaces contenant un premier liquide, comprenant un agent oxydant, ainsi qu'un second liquide, comprenant un adjuvant ou un agent de chélation, ces liquides restant, à l'origine, séparés. L'appareil est conçu pour faciliter la sortie de ces deux liquides en les combinant de manière à constituer un mélange au moment de les répandre sur la surface à traiter. L'un de ces liquides, sinon les deux, renferme un agent d'ajustement de pH, présent sous une quantité telle qu'au moment de la sortie des liquides, le mélange obtenu conserve un pH suffisant pour garantir tant l'efficacité du nettoyage que la stabilité de l'agent oxydant. Cette invention porte également sur une composition obtenue grâce à un procédé maintenant séparés les deux liquides susmentionnés et ne les laissant se mêler qu'au moment où ils vont se répandre sur la surface à traiter.
