I don’t remember precisely what properties we scored it on, but we had cooked a very messy/crusty/greasy meal of some sort, and afterward we washed the pans with two or three leading dish soaps. I think Joy was the third. Anyway, Palmolive seemed to perform the best overall at cutting through grease and grime in fewer passes. I know there were other aspects to it, but it was just too long ago to recall. I never forgot how impressed I was with Palmolive, though. And it’s green!
