4. Bleach + vinegar
The combination sounds like it’d be a powerful disinfectant, but the two should never be mixed. Together, they produce chlorine gas, which even at low levels, can cause coughing, breathing problems, and burning, watery eyes.

5. Bleach + ammonia
Bleach and ammonia produces a toxic gas called chloramine. “It causes the same symptoms as bleach and vinegar — along with shortness of breath and chest pain.” says Forte. Many glass and window cleaners contain ammonia, so never mix those with bleach.
6. Compound Henna Hair Dye + Hydrogen Peroxide
Ok, it’s not a cleaning product, but some people still use it. Most henna hair dyes that purport to color hair any color other than red contains metallic salts. These hair dyes are called compound henna hair dyes. Dyeing your hair with any permanent dye containing hydrogen peroxide up to a year or two after using a compound henna product could result in an adverse reaction, so always test hair dye on a hair sample taken from your hairbrush before applying.
When hydrogen peroxide comes into contact with metalloids or metal salts, a violent explosion could occur. A chemical reaction could result in foul odor and smoke, which could burn your scalp. A damaged scalp could lead to increased absorption of the nasty chemicals already present in most permanent hair dyes.
7. Bleach + rubbing alcohol
Unless you’re trying to kidnap somebody (yeah, it’s that serious) then never mix these two. Ever heard of chloroform? That’s the stuff kidnappers in the movies put on rags to knock out their victims? Although it might not actually make you pass out, this combination can be irritating and toxic.
Here’s some things to always remember:
Make it a rule to never mix bleach with anything but plain water.
Make sure that you do not mix bleach with any other cleaning agent except water. That is the best and the safest way to use it. Even two cleaners from different brands should not be mixed. There could be some harmful reaction happening upon mixing which could cause you troubles later on. Upon mixing any two cleaning products without appropriate knowledge of their ingredients can cause problems such as:
– Coughing
– Shortness of breath
– Pain in chest
– Wheezing
– Nausea
– Watery eyes
– Irritation to throat, eyes and skin
– Runny nose
Before mixing any two ingredients make sure you read the manufacturer’s instructions carefully. And do not transfer such cleaners into any other container so that you have the product related information handy with you as and when needed.
