The inventors of the present disclosure recognized that, surprisingly, the antimicrobial treatments used on cellulosic sponges do not work in hydrophilic polyurethane sponges. As such, the inventors of the present disclosure discovered a need for an antimicrobial treatment for use on hydrophilic polyurethane foam sponges. The present inventors invented one antimicrobial composition for use on hydrophilic polyurethane foam sponges including an acetate salt solution humectant. The present inventors invented another antimicrobial composition for use on hydrophilic polyurethane foam sponges including a non-halogen humectant comprising a salt solution having a pH between about 3 and 10 and a water activity of less than 0.9 at 25 DEG C.
