The 2013 tests from Consumer Reports list Wisk Deep Clean as the best detergent, while Good Housekeeping's 2012 test names Ultra Tide as the best. The runner-ups in each test were Costco's Kirkland Signature and Gain Dazzle & Shine, respectively.
The Consumer Reports' rankings consider price, toughness and safety. The Good Housekeeping rankings look at the best detergents in particular categories. For example, Good Housekeeping lists Tide Plus as the best liquid detergent, Ultra Tide Coldwater as the best cold water powder detergent, Gain Original as the best cold water liquid detergent and Target's Up & Up 2X HE as the best value detergent.
