Combining bleach and vinegar (or another acid) releases chlorine gas, which is toxic. While only one poisoning case was recorded by French poison control centres from 2002 to 2013, this number has risen to 203 since the ban on the use of certain herbicides by the general public came into effect in 2019.
Here are some common dangerous combinations to avoid: Bleach + Vinegar = Chlorine gas. This can cause coughing, trouble breathing, burning, and watery eyes. Bleach + Ammonia = Chloramine gas.
Bleach and vinegar mixture produces chlorine gas, which can cause coughing, breathing problems, burning and watery eyes. Bleach and ammonia produce a toxic gas called chloramine. It causes shortness of breath and chest pain. Bleach and rubbing alcohol makes chloroform, which is highly toxic.
Household chlorine bleach can release chlorine gas if it is mixed with certain other cleaning products. Do not mix household cleaners! If chlorine is in the air, people can be exposed through skin or eye contact, or breathing in the chlorine gas.
Any acid mixed with bleach is a big no-no. Potential to make chlorine gas and really hurt yourself. General rule is never mix cleaning products. Just buy anti-mould spray from a supermarket or hardware store.
Vinegar's acidic properties kill most types of mold effectively. Hydrogen Peroxide: For tougher mold, mix three parts water with one part hydrogen peroxide. Spray the solution and allow it to sit for 10-15 minutes before scrubbing. Baking Soda: Dissolve 1 teaspoon of baking soda in 2 cups of water.
Vinegar is generally better for killing mold on porous surfaces because it penetrates roots and prevents regrowth, while bleach is better for non-porous surfaces (like tile) where it kills surface mold but doesn't stop roots and can damage porous materials; however, for large mold issues, professionals are recommended as both have limitations and bleach releases toxic fumes, making vinegar safer.

High-level Exposures
Concentrations of about 400 ppm and beyond are generally fatal over 30 minutes, and at 1,000 ppm and above, fatality ensues within only a few minutes. A spectrum of clinical findings may be present in those exposed to high levels of chlorine.
Vinegar is one such substance that is erroneously purported to have a neutralizing effect on bleach. Instead, vinegar acts on the hypochlorite content of bleach, turning it into hypochlorous acid and other dangerous chemicals. Hypochlorous acid can convert to deadly chlorine gas in a low pH solution.
But eight places you should never use vinegar include:
However, this can occur when heavy rainfall meets blocked drains, and the drainpipes are unable to handle the volume of rainwater due to an outside drain blockage. That's why households are being encouraged to pour vinegar into their drains to help keep them clear.
It can repel spiders. So if creepy crawlies are keeping you inside, this household staple to banish spiders from your porch or patio is undoubtedly worth a try.
Combining bleach and vinegar (or another acid) releases chlorine gas, which is toxic.

If you or someone else ingests concentrated vinegar, or if severe irritation occurs with skin or eye contact, you should immediately contact medical care. If you inhale toxic fumes, go out into fresh air and call emergency services if breathing is severely affected.
Substances that Kill Weeds Permanently
Bleach is highly effective in killing mature weeds, and unlike vinegar, will prevent new weeds from coming back because it remains in the soil.
Acute exposure at high levels causes dyspnea, violent cough, nausea, vomiting, lightheadedness, headache, chest pain, abdominal discomfort, and corneal burns, in addition to the same symptoms of low-level acute exposure. Chronic exposure to chlorine gas can lead to chest pain, cough, sore throat, and hemoptysis.
Chlorine's usefulness was short-lived. Its color and odor made it easy to spot, and since chlorine is water-soluble even soldiers without gas masks could minimize its effect by placing water-soaked - even urine-soaked - rags over their mouths and noses.
When high levels of CO enter your body, it can be deadly after only a few minutes. The most common symptoms of CO poisoning are a headache and shortness of breath.
Seven places you should never use bleach include:
The reasons include, corrosiveness, safety, smell, eco-credentials and real measurable efficacy advantages over bleach, at much lower concentrations."
“Of course, vinegar does eliminate some things, but it's important to note it's not a complete solution to disinfectant. It is only 90% effective against bacteria and around 80 percent effective against viruses and mold or mildew. Bleach, however, eliminates 99.9% of bacteria, viruses, and mold or mildew.
While vinegar can handle small mold problems, large infestations, hidden mold, or recurring growth usually require professional remediation. Prevention is the real long-term solution. Whether you use vinegar or another cleaner, mold will return unless you address the underlying cause: excess moisture.
Symptoms caused by a mold allergy can include:
Bleach Can Worsen Mold Infestation
So once the chlorine evaporates and only the water is left, it will soak into the surface and feed the mold spores underneath it. This will make the infestation worse.
