The following information is from the OU in response to a reader's question on January 21, 2014.

"The Finish Jet Dry Rinse Agent (these exact words), is certified kosher even when not bearing the OU symbol.
It is generally assumed that dishwashing detergents are not edible entities, and Halachically they do not have a non-kosher status even if they contain non-kosher ingredients, as is often the case. Nonetheless, some Poskim maintain that it has been the established Minhag Yisrael (Jewish custom) to use kosher detergents on plates, pots and utensils as they come in contact with food. An OU on a detergent insures the kosher status of that product. That said, if one used non-certified dishwashing detergent, Bidieved (after the fact), the kosher status of the utensils would not be compromised."
