Cleaning Chemicals Don’t Mix

Searching for alternative cleaning products? Not everything can be safely combined! Here are a few dangerous combinations to avoid.

  • Bleach & Vinegar
    • Can produce chlorine gas, which even at low levels, can cause coughing, breathing problems, and burning, watery eyes.
  • Baking Soda & Vinegar
    • When you combine these ingredients, you mix an acid and a base, leaving you with an ineffective supply of saltwater and carbon dioxide gas.
    • Vinegar causes baking soda to foam up; if stored in a closed container, the mixture can explode.
  • Bleach & Ammonia
    • Can produce a toxic gas called chloramine, which can cause coughing, shortness of breath, chest pain and burning, watery eyes.
    • Many glass and window cleaners contain ammonia, so never mix those with bleach.
  • Hydrogen Peroxide & Vinegar
    • Produces peracetic acid, which is potentially toxic and can irritate the skin, eyes, and respiratory system.
    • It is okay to use the products in alternating mists, wiping down surfaces between sprays. Do not mix in the same container.
  • Bleach & Rubbing Alchohol
    • Produces chloroform, which can be irritating and highly toxic.
  • Drain Cleaners
    • Drain cleaners have a number of strong cleaning chemicals in them, and each brand is different. They should never be mixed, if one does not work, call a plumber.
