Edward has done some preliminary tests using Method Dish Soap in a "standard" guar gum-based juice by substituting Method Dish Soap for Dawn Pro. Initial tests indicate that this detergent works quite well but is somewhat weaker than Dawn Pro.
Initial tests indicate that this detergent is a bit weaker than Dawn Pro (Method at 20:1 had a similar color profile as Dawn Pro at 32:1). So, you need to use something like 1.3 times as much Method as Dawn Pro when substituting. Method is quite sensitive to whatever it is that baking powder or baking soda+citric acid do (which is probably related to pH adjustment). In a test session (2013/09/10), a 20:1 dilution with guar gum did not work at all until baking powder was added at which point the mix performed quite well.
pH sensitivity: Method seems to be sensititive to the solution pH (if the contribution of baking powder is to adjust pH). Use of baking powder or baking soda+citric acid is recommend. Target pH currently unknown. My best guess is somewhere in the 7.0 to 7.6 range. The adjustment makes the juice both more bubble friendly and thins the film (essentially boosting the effectiveness of the surfactant).
