The Basics of pH
Green cleaning works because it’s based on simple chemisty, i.e. the pH scale. pH is a measure of how acidic or basic (alkaline) a solution is. Each whole number difference on the 0-14 scale represents a tenfold change. Highly acidic and basic ingredients can irritate the skin in concentrated forms!
Low pH (0-7) = Acidic
A solution having a pH that is lower than 7 is acidic. Acidic cleaners attack and dissolve alkaline soils, like mineral deposits or rust, breaking them down and making them easier to remove. E.g. vinegar, citrus or anything that would have a sour or bitter taste.
High pH (7-14) = Basic (alkaline)
A solution with a pH that is higher than 7 is basic. Alkaline cleans attack fatty and oily soils breaking them into component parts that are easier to remove from the surface or fabric.
