The Dangers of Mixing Cleaning Chemicals

The Coronavirus pandemic has caused massive demand for popular, common household cleaning chemicals such as disinfectants (common quaternary ammonium compounds) including Benzalkonium Chloride aka Coles Disinfectant.

This has resulted in widespread shortages of these and other disinfectant products. So it is perhaps no surprise that many people are turning to alternative cleaning products, and perhaps even mixing their own concoctions.

When using a combination of cleaning chemicals or mixing them together however, some common household chemicals produce dangerous reactions, such as the creation of toxic gases.

How to Avoid Dangerous Chemical Reactions

Always use chemicals according to the label. Check the Safety Data Sheets before using a combination of cleaning products.

Never Mix These Chemicals!

Bleach + Vinegar (or Lemon Juice)

Creates Chlorine Gas, which is toxic and irritating to the respiratory system and eyes.

Bleach + Ammonia

Creates Chloramine, a toxic gas which can cause chest pain and shortness of breath.

Bleach + Rubbing Alcohol (or Alcohol in any form including Isopropyl Alcohol and Ethanol)

Creates Chloroform which is highly toxic.

Hydrogen Peroxide + Vinegar

Creates Peroxyacetic acid which while being a more powerful disinfectant, is highly corrosive.
