Cleaning is defined as removal of contaminants. Disinfectants are a type of cleaning agents known to inactivate microorganisms. The efficacy of a disinfectant itself can be tested using a suspension test. The disinfectant at its working strength is challenged with a suspension containing a known titer of a microorganism. For testing the disinfectant in the actual cleaning process, the efficacy of a disinfectant on a contaminated surface can be tested using the surface sampling method. Surfaces, as used by the client, are spiked with bacterial load and subsequently exposed to the disinfection process. Using both methods, the reduction of the microbial load is determined.
The products to be tested are the disinfectants used in the cleaning procedures of the client. For example:
