Lemon And Bleach

Even combining something as harmless as a lemon with bleach can be harmful. That’s all thanks to lemon’s makeup, which is acidic. The combination of these two can result in a toxic, harmful gas. It’s better to leave these two separately, and if you’re tempted to clean, choose one (Purdy and Figg).

Oven Cleaner And Ammonia

As we’ve already learned, it’s never safe to combine ammonia with any other household chemicals. It can create toxic fumes, and if you accidentally breathe it in without wearing the proper protective equipment, the combination can be extremely toxic to your health. This is exactly the case with oven cleaners and ammonia. Don’t even think about putting the two chemicals near each other! (Fabulessly Frugal).

Glass Cleaner And Bleach

Even if your windows are looking dirty and foggy, that doesn’t mean you should grab both the glass cleaner and bleach. Never combine these two, all because of their chemicals. Glass cleaner contains ammonia, and as we’ve learned ammonia and bleach together is a huge no-no. The combination is called sodium hypochlorite, which produces chloramine vapor, a highly toxic substance. Side effects from this are choking, coughing, sinus congestion, and shortness of breath (ABC27).

Baking Soda And Vinegar

While the byproducts of baking soda and vinegar aren’t necessarily harmful, since it’s only water, sodium acetate, and carbon dioxide, it’s not safe, either. According to Vy Dong Ph.D., a professor at the University of California, when combining the two “carbon dioxide is a gas, and having this reaction occur in a sealed container can cause a small explosion as carbon dioxide tries to escape.” You might have your very own erupting volcano in your home (Insider).
