An aqueous composition for the reduction or elimination of unpleasant odors from surfaces containing such odors comprises a perfume, a surfactant/solubilizer, a solvent/drying aid, an odor absorber, and, preferably, a buffer to maintain the desired pH. The solution contains minimal or no volatile organic compounds. Due to the specific nature of the combination of the surfactant/solubilizer and the solvent/drying aid, the use of fragrances previously too hydrophobic for use in an aqueous solution is possible, providing a large variety of efficient odor counteractants not previously available. The composition may optionally comprise additional components, such as preservatives, antimicrobials, anti-static compositions, anti-wrinkling agents, insect control agents, moth repellents, UV protectants, water-proofing agents, and textile treatment agents. The aqueous solution may be applied to a variety of surfaces, in sufficient quantity to wet the surface, preferably by spraying.
