Cleaning and Disinfection Process (CDP)

Cleaning and Disinfection does not imply that all surfaces will be 100% free of coronavirus and therefore it will be described as a Cleaning and Disinfection Process (CDP). This process is an actual strategic process to significantly reduce the hazard and exposure from a surface or environment and it is important that the client and all parties understand this reality. The cleaning process is often the first step and is the act of removing soils, debris or residue from a surface before the application of a disinfectant. Some surfaces may require more cleaning that others and should be evaluated prior to the process during the preliminary assessment.

Cleaning and the use of "cleaners" often requires the application of a detergent, soap, surfactant or similar product designed to loosen or help remove the biological residue or soil from a surface, but is not designed to destroy the virus by itself. Some surfaces might require slight pressure or agitation to the surface to perform proper cleaning effectiveness. If using a liquid/wet cleaning agent, the surfaces will need to be dried prior to applying a disinfectant. Cleaning products need to be compatible and designed for the surfaces they are applied to and used in accordance with the master label and Safety Data Sheet (SDS).

The application of a disinfectant is the process of destroying, making the viral pathogen inactive or eliminating its infectious properties. There are over 250 approved disinfectants listed on the EPA website for emerging viral pathogens and human coronavirus (SARS-CoV-2. The disinfecting process follows the cleaning process, and should include the use of an EPA-registered disinfectants listed on List N (See
