Even though production facility ceilings, walls and floors are not in direct contact with products, the cleaning and disinfecting of these surfaces is an important measure to maintain or restore the desired purity in the production areas and thus to preserve product security.
Because cleaning and disinfection of large cleanroom areas is usually a manual task, simple and systematic workflows are needed to achieve the desired validity of the processes. As a rule of thumb, the less possibility there is for operator error, the more reproducible and safe the process will be. The following article describes the implementation of a simple, valid cleanroom-specific mop disinfection process for GMP areas.
