Best Eco-Friendly Liquid Dish Detergent

All dish detergents rely on chemical surfactants that mix oil and water to wash dirt and grease away. Conventional detergents use petroleum-based surfactants. A new generation of eco-friendly detergents takes advantage of vegetable-based ones. To make sure their products perform well, manufacturers of eco-friendly detergents often increase the surfactant concentration. This makes these detergents more expensive than conventional ones, but gives them plenty of cleaning power. And if you're on a save-the-planet kick, they're relatively guilt-free.
