Disclosed are methods, compositions and articles suitable for controlling the undesirable ammonia odor produced by excreted or secreted body fluids, e.g., urine and/or sweat, and residues thereof. Such methods, compositions and articles utilize certain urease inhibitor complexes formed from a divalent metal ion and a polyanionic, preferably amine-based, chelating agent to prevent or minimize the urease-promoted degradation of urea (found in the body fluids) to malodorous ammonia.
