What is Ph Neutral? Ph Neutral is when a chemical has a Ph reading of 7, which is halfway on the PH scale; products with a Ph lower than 7 are acidic and great for use in bathrooms, and a Ph more significant than 7 are alkaline and used with in open area floor cleaning. Ph-neutral detergents are safe on most washable surfaces and can be as effective as non-neutral chemicals for floor cleaning, dishwashing, car washing and all-around general cleaning.
