A lubricant composition is provided. The lubricant composition includes a machinery lubricant and an antimicrobially effective amount of an antimicrobial agent. The antimicrobial agent exhibits a partition coefficient between water and the machinery lubricant of between about 0.01 and about 1,000, and the lubricant composition provides at least a two log reduction in bacteria in water in about two weeks or at least a two log reduction in mold and yeast in water in about one month from a concentration of bacteria of between 105 and 106 CFU/ml and a mold and yeast concentration of between about 105 and 106 CFU/ml. Methods for manufacturing and using a lubricant composition are provided. A method for manufacturing a lubricant composition is provided.
