Abstract:

Methods of treating an inanimate object or inanimate surface which has malodor impression to reduce the malodor impression comprise the step of contacting the inanimate object or inanimate surface with an effective amount of a composition for reducing malodor impression comprising: (a) from about 0. 1% to about 1%, by weight of the composition, of perfume; (b) from about 0. 1% to about 10%, by weight of the composition, of metallic salt; (c) optionally, solubilizing aid; and (d) aqueous carrier. The compositions used in the methods are essentially free of any material that would soil or stain fabric. The inanimate surface treated via the present methods is preferably fabric.
