Interaction of disinfectant residues on cleanroom substrates

This study will determine the levels of disinfectant residues on stainless steel surfaces after simulated manual cleaning activities. Additionally, this study will determine if chemical interactions between different chemical agents, representative of commonly used cleanroom disinfectant technologies, subsequently applied to the same surfaces exist, and to what degree these interactions impact sporicidal performance of an oxidizing biocide against Bacillus subtilis.
