The possibility of ''clean milk''-dairy produced without the need for cows-has been championed by several charities, companies, and individuals. One can ask how those critical of the contemporary dairy industry, including especially vegans and others sympathetic to animal rights, should respond to this prospect. In this paper, I explore three kinds of challenges that such people may have to clean milk: first, that producing clean milk fails to respect animals; second, that humans should not consume dairy products; and third, that the creation of clean milk would affirm human superiority over cows. None of these challenges, I argue, gives us reason to reject clean milk. I thus conclude that the prospect is one that animal activists should both welcome and embrace.
