I have mixed feelings about all this.

I agree that "Dirty" as a word, probably shouldn't be on the label of a food product, and particularly on a milk.
Dirty/Clean was a clever idea. I think we can all get the pun. but it only works on a native English speaker and even then, it's a bit too clever by half.

I also agree with Stockcount in that you don't want a sterile name.

Also, there's plenty of cliche words in names already. Some terms are overused and just sound banal including anything starting with a prefix of eco.... Even my own thought-fart of "Earthy Clean Food" has a good dose of eco-cliche about it.

On a tangent. I thought is was funny hearing Matt in that video recently saying Buntine Protein... I kept hearing, Bunting Proting
