In the final report the next section would deal with cleaning process design.  It should include references to standard operating procedures and how they were evaluated. Next, include section of data analysis that provides statistical justification for the conclusions reached.  A defined procedure for changing validated processes is necessary.  It should describe approval and review processes required when making specific changes.  Provisions for emergency changes should be made.  There should also be a list of assumptions made, to be reviewed whenever anything is changed (eg..hardest to clean or most toxic).  Include a review of validated processes during the annual product review (APR). Use it as an opportunity to determine whether all the minor changes made, since the previous review do not amount to significant changes that exceed the assumptions made and require a revalidation. Typically a revalidation is required when the cleaner has been changed.  It may be appropriate to continue an old cleaning operation while phasing in a new one.  Monitor the new process to prove that it produces the same validated results as the old one. 

The final section of the final validation report would have the references to any standard methods, journal articles, or government documents.

In selecting an aqueous cleaner for GMP manufacturing, where a cleaning validation is required, consider both the efficacy of the cleaner and the ability of the cleaner manufacturer to support your validation efforts.  What to look for from a cleaner manufacturer:

·        Lot traceability of the cleaners

·        Certificates of Analysis for the cleaners

·        Consistent manufacturing

·        Ingredient disclosures under confidentiality

·        Cooperation with audits and quality questionnaires

·        Ingredient toxicity data

·        Ingredient reactivity information to help determine degradations and interactions

·        Cleaner shelf life information

·        Residue detection method information

·        Residue sampling information

·        Acceptance limits information

·        Recovery information

·        Residue detection methods validation information

·        Assistance with written cleaning procedures
