Dont Mix


As much as I love cleaning with vinegar, it is important to know that it should not be directly mixed with hydrogen peroxide, baking soda, or Castile soap. When any of these 3 ingredients are mixed with vinegar, they can become irritants or lose their efficiency.

  1. Vinegar + Hydrogen Peroxide = Peracetic Acid, which can be absorbed into the skin and can cause redness, pain, blisters, or skin burns, as well as affecting breathing if inhaled.
  2. Vinegar + Baking Soda = Salt Water. The two are strong cleaners on their own, but the alkalinity of baking soda with the acidity of vinegar ultimately crosses the other out.
  3. Vinegar + Castile Soap = Unsaponafied, Curdled Soap. (source, Lisa Bronner, of Bronner’s Castile Soap)

Other Things You Shouldn’t Mix

  1. Bleach + Vinegar = Toxic Chlorine Gas
  2. Ammonia + Bleach = Toxic Chloramine Vapors
  3. Rubbing Alcohol + Bleach = Chloroform
  4. Hydrogen Peroxide + Vinegar = Parecetic Acid
  5. Baking Soda + Vinegar = Salt water, an Ineffective Cleaning Solution
  6. Vinegar + Hydrogen Peroxide = Peracetic Acid
  7. Vinegar + Castile Soap = Unsaponafied, Curdled Soap
