Dishwasher detergent buying guide

Imagine your toughest pile of dishes--maybe a few hours after a big family meal, plates covered in sticky cranberry sauce, pots coated in grease and stuck-on mashed potatoes. That's nothing compared to the torture test we create for dishwasher detergents. First there's the gnarly mix of peanut butter, egg yolk, and other sticky foods that we smear on dishware. Pans get a coating of baked-on mac and cheese. It ain't pretty, but it is effective at figuring out which detergents are truly up to the challenge. And our latest tests had a few surprises.For starters, the market continues to move toward single-dose detergents, those familiar pods and pacs that you conveniently pop into the dishwasher detergent. Most of our top-performing detergents now comes in this formulation. Another new development: some store brands are starting to rival the name-brand competition. That's good news since store brands typically sell for much less, which means the cost of doing dishes could go way down­ without compromising on cleaning power--though only if use the detergents and your dishwasher properly.
