Why Bleach and Other Cleaners don’t Mix


Bleach is a controversial cleaner when it comes to household use. With the impact it can have on our health and the environment, individuals have tried to decrease the amount of bleach they use. But here’s the thing, as long as you use it correctly there’s no reason to use it less. If you use bleach–or are thinking about using it–this blog covers a few things to keep in mind.

Killer combinations

Used separately, these cleaners are safe and effective to use around your home. But if mixed with bleach, either deliberately or accidentally, they create toxic and potentially fatal products.

  1.  Bleach and Ammonia – This combination is one of the most well-known no-nos. It’s also the reason why most people recommend not mixing bleach with other cleaners. Most cleaners contain ammonia, which when combined with bleach, produces chloramine gas. Exposure to chloramine gas can cause burning or stinging in your eyes, nose, and respiratory system. In more extreme cases, it can also cause internal organ damage.
  2.  Bleach and Vinegar – Vinegar on its own makes a great cleaning agent, but when mixed with bleach results can be disastrous. This combination produces chlorine gas, which in high amounts can be deadly. Chlorine gas can also cause coughing, irritation of mucus membranes, and if it comes in contact with the skin, chemical burns.
  3.  Bleach and Rubbing Alcohol – This combination can create many deadly substances including chloroform, hydrochloric acid, and chloroacetone. Each of these can cause chemical burns, lead to internal organ damage, and even knock a person out.

Serious Symptoms

Exposure to any of these toxic gases produced from mixing chemicals can cause many symptoms ranging from skin irritation to unconsciousness and even death.  If you’ve been exposed, you may experience the following symptoms:

  •       Burning, reddening, or blistering skin.
  •       Burning sensation in the eyes, nose, and throat.
  •       Chest tightness or difficulty breathing
  •       Nausea and vomiting

How to use Bleach the Right Way

It’s important to note that bleach is not a cleaner; it’s labeled as a disinfectant. Meaning surfaces should be cleaned first, then disinfected with bleach if needed. Bleach should always be stored in a cool, dark place, kept away from children, and used with gloves and eye protection if there’s a risk of contact exposure or splashing.

On its own this is a substance not to be trifled with, which is why it needs to be diluted. A bleach to water ratio of 1:99 is suitable for general household use, while a ratio of 1:50 is recommended for surfaces contaminated with bodily fluids (i.e. vomit, urine, blood etc.). When diluting, remember to use cold water only! Using hot or boiling water will cause the active ingredients to break down and lose their effectiveness.
