New bottle That bottle of Dawn Simply Clean (Original Scent, 12.6 fl oz / 375 mL, Non-Concentrated) was part of a short-run packaging design used by Procter Gamble between 2016 and 2018 in the U.S. Here?s the breakdown: The ?Simply Clean? sub-line was introduced as a budget, lighter-formula version of Dawn Ultra and phased out around 2019 when P G consolidated the branding back under ?Dawn Ultra.? The non-concentrated labeling and this exact blue liquid in a rounded 12.6-oz bottle match SKU 037000827894, which appears in P G?s retail listings from late 2016 through 2018. Later bottles (post-2019) dropped the ?Simply Clean? name entirely. So your bottle is likely from circa 2017?2018, part of that discontinued line.
