Best Dish Soaps & Detergents

Dish soap is the most-used cleaning product in the house, and the differences between the top brands are larger than people assume. The three categories are hand-wash liquid (Dawn, Seventh Generation, Method), automatic dishwasher detergent (pods, powder, or gel), and specialty soaps (for cast iron, fragile glassware, or stainless). Hand-wash performance comes down to surfactant density; cheap generic soaps dilute with water, and you end up using three times as much to cut the same grease.

Dawn Ultra sets the bar for grease-cutting and Seventh Generation matches it without synthetic dyes and fragrances. For automatic dishwashers, pods outperform powder and gel by a wide margin; built-in enzymes, rinse aid, and prewash bead all in one unit. The biggest dishwasher mistake is buying pods without an enzyme component; they can't break down protein (eggs, cheese, dried-on oatmeal) and leave glasses streaky.

We tested each soap under identical conditions: 30-piece greasy-pan wash-up, 12-load dishwasher cycle with mixed soiled dishes, and a 24-hour dried-on test. Rankings weigh grease-cutting power, scent (and whether that scent lingers on dishes), skin feel, packaging, and whether the formulation is septic-safe for homes on well water.
