This version of Dawn Ultra works quite well and actually is more concentrated that Dawn Pro and most other versions of Dawn. Many people (as of mid-201) actually prefer this to Dawn Pro. Use 2/3 as much ultra 3x as you would Dawn Pro or Fairy or Dreft or other Dawn products. It also requires some more of your preferred pH adjuster as those other dishwashing liquids.
Important note about substituting for Dawn Pro or Fairy. It actually has greater surfactancy than Dawn Pro (unlike some other Dawn products which claim to be highly concentrate but don't have higher surfactancy). Use 2/3 as much Dawn Ultra 3x as you would Dawn Pro, full-strength Fairy, etc.
