last to rinse

Q. What does “detergent is the last to leave the equipment surface” after rinsing mean? This seems like a broad statement, can it be supported by literature/documentation?
A. The only source of “detergent last to rinse” that I am aware of is based on the physical behavior of surface active agents and the interchangeable use of the word detergent and surfactant in common usage. More properly you should say the surfactant is the last to rinse. Learn More about Surfactant.
