Cleaning Method Groupings

As mentioned in the discussion of utensils and small equipment, it may be appropriate to group
cleaning studies based upon the utilization of a single cleaning method.

The validation of the cleaning procedure may be conducted almost independently of the equipment for which it is used.

As long as the range of equipment configuration and product formulation are used to challenge the cleaning method, this grouping, when scientifically applied, is as appropriate as any of the other grouping philosophies.
