Why Do Disinfectant Residues Matter

Historically, cleaning has been the “residual contaminant” removal step and disinfection has followed, often at times leaving the disinfectant on the surfaces indefinitely. Legacy cleanroom environments were often following the old adage that “visible disinfectant residues on the surface are a preventative measure.” But this rationale may be changing. The authors have seen a prolonged and increased concern from regulators over residues left from disinfectants post-application. 

Current industry thinking, along with recent compliance mandates, is that any residual chemical is a potential chemical or particulate contaminant to a process and possibly to product. This renewed focus has led a change from legacy thinking to a consideration of how to assess and address disinfectant residues, including an evaluation of what properties other than efficacy, such as residue profile, should be considered for cleaning and disinfectant products.
