The data used to determine the success of a cleaning validation is built upon both the effective evaluation of the manufacturing plant and the robustness of the validated analytical method. In order to ensure the safety of the consumer, there must be a high degree of confidence in the analytical results in order verify the absence of residues at the prescribed limits on the various equipment surfaces. This white paper discusses the over-arching strategy for performing a successful cleaning validation, with detail on some of the key factors to consider at both the manufacturing and analytical stages, highlighting many common pitfalls to avoid.
