Since I do alot of dish washing at home, I come to try out many different dishwashing soap.  And I have come to the conclusion that Palmolive is one of the best if not the best.  It cuts grease from pots and pans and after washing, I feel my dishes and pans very clean.  With other detergents, I feel I have to use a larger amount of soap and work harder to get the grease/stains off.  It's the only brand I would buy.
