RK, what are you trying to remove? What are you trying to remove it from? And, what type of equipment do you have?
Generically, I suggest a saponifier, related to other aqueous chemistries, is associated with: -- higher PH -- need for effective chemical isolation from wash to rinse -- need to rinse really well -- higher temperatures and energy/$ -- wash bath turn-over --possible oxidation/discoloration/foaming concerns
A saponifier related to semi-aqueous and solvent chemistries has compelling advantages. If not needed, a saponifier related to water only has strong disadvantages. That said, with low standoff components and more challenging end-use demands, manufacturers are seeing the advantages of a cleaning chemistry out weigh the associated disadvantages.
Hope this is useful information.
