Cleaning validation is undertaken to demonstrate that a cleaning and disinfection programme has been designed to meet the objective of the clean and that that when undertaken correctly, meets these objectives.  It is thus proof, based on physical testing, that the designed cleaning and disinfection programme works. In the context of ISO 9000-2000, this process is named qualification. Validation is used in a much broader sense e.g. for validation of cleaning.

Cleaning verification is the demonstration that on subsequent cleaning occasions, the cleaning and disinfection programme met its objectives.  Cleaning verification is usually by microbiological testing for a total viable count (TVC) or absence of a specific pathogen (e.g. Listeria monocytogenes) or allergens.

A virucide is an agent (physical or chemical) that deactivates or destroys viruses.
