Improved odor-reducing compositions, and corresponding methods, are disclosed wherein a substrate or area exhibiting undesirable odors is treated with an odor-reducing composition including respective quantities of citric acid and a salt of citric acid. Preferably, the odor-reducing composition in particulate form includes from about 0.1-20% by weight citric acid, at least about 50% by weight of a salt of citric acid (e.g. sodium citrate) and an anti-caking agent. The compositions of the invention may be used to good effect in the treatment of substrates such as human skin, cloth or other absorbents; or in deodorizing areas exhibiting offensive odors.
