A word from Denise
They do not. So make yourself one rule and keep it every time: one bottle at a time, rinse with water, then the next. Write that Poison Help number on a piece of tape inside your cabinet door today. I hope you never need it.
Every line in this chart is checked against the health department, CDC, EPA, Poison Control and label sources listed at the bottom.

Can you mix vinegar and bleach? No. Bleach mixed with vinegar, or with any acid, gives off chlorine gas, which burns the eyes, nose, throat and lungs.
Bleach + ammonia
(and anything with ammonia in it, like some glass and window cleaners)
What happens: Chloramine gas
Coughing, shortness of breath, chest pain, wheezing, nausea, watery eyes, irritation of the throat, nose and eyes; pneumonia and fluid in the lungs
Checked against: NJ DOH, WA DOH, EPA, bleach label
Bleach + vinegar
What happens: Chlorine gas (NJ also lists chloramine among the vapors)
Burning, watery eyes, coughing, breathing trouble; at higher levels chest pain, vomiting, pneumonia and fluid in the lungs
Checked against: NJ DOH, WA DOH, Poison Control
Bleach + any acid: lemon juice, toilet bowl cleaners, rust removers, some glass cleaners, dishwasher detergents and rinses, brick and concrete cleaners, mildew stain removers
What happens: Chlorine gas
Burning, watery eyes, coughing, breathing trouble; at higher levels chest pain, vomiting, pneumonia and fluid in the lungs
Checked against: NJ DOH, WA DOH, bleach label
Bleach + rubbing alcohol
What happens: Chloroform and other harmful chemicals
Dizziness, nausea, headaches, loss of consciousness
Checked against: NJ DOH
Bleach + drain cleaner
What happens: Harmful gases
Drain cleaners can contain acids; health departments list them as never to mix with bleach
Checked against: NJ DOH, WA DOH
Bleach + oven cleaner, hydrogen peroxide or some insecticides
What happens: Bleach reacts with these
Health departments list them as never to mix with bleach
Checked against: NJ DOH (oven cleaner), WA DOH
Hydrogen peroxide + vinegar, in one bottle or container
What happens: Peracetic acid
Can irritate and harm the eyes, skin and lungs
Checked against: NJ DOH
Drain cleaner + a second, different drain cleaner
What happens: They can react with each other
Never pour a second drain cleaner on top of the first, even a different brand
Checked against: NJ DOH
OxiClean or other oxygen bleach powder + ammonia, chlorine bleach or other household chemicals
What happens: Not stated on the label
The label says do not mix, and do not store a mixed solution in a closed container
Checked against: OxiClean label
Pool chlorine (tablets or powder) + other cleaning products
What happens: Pool chemicals contain the same kind of chlorine as bleach
Keep them away from other cleaners
Checked against: WA DOH
Baking soda + vinegar
They neutralize each other into water, a salt (sodium acetate) and carbon dioxide gas. The fizz looks busy but leaves you with a weaker cleaner than either one alone. In a closed bottle the gas has nowhere to go, so never cap it.
Checked against: The Conversation (Nathan Kilah, University of Tasmania)
Washing soda + vinegar
Same idea: an acid and a strong alkali cancel each other out. The maker’s safety sheet lists acids as something to keep washing soda away from.
Checked against: Sodium carbonate safety data sheet
You can mix two products without ever opening a jug of ammonia or acid, because a lot of everyday cleaners already have them inside. The Washington State Department of Health lists these.
How you will know: CDC says chlorine gas smells like bleach, and most people notice the smell or the irritation in their eyes, nose and throat first. If a cleaning job suddenly smells sharp, or your eyes and throat start to burn, stop and leave.
A few habits keep an accident like that from ever starting.

Bleach labels ask for them. up&up latex gloves were $3.39 and latex-free $3.89 at Target.com on 11/6/2026.
Bleach labels ask for those too.
The free Kitchen and Laundry Rescue Guide includes this never-mix chart as a one-page printable, plus the Poison Help number in big print.

Here is what is happening in that bucket. Bleach is strong because of the chlorine in it. Put it with an acid like vinegar, and some of that chlorine comes out of the water as a gas you breathe.
Put bleach with ammonia and you get a different gas, chloramine, that hurts your lungs just the same. None of these mixes cleans better than the product alone. They only make the air in the room dangerous.
Baby, this is the page I care about most. Nobody pours bleach into ammonia on purpose. It happens when you are tired and in a hurry: you hit the toilet with one cleaner, then reach for the bleach to finish the job. Or you figure two good cleaners must make one great one.

No. Vinegar is an acid, and bleach mixed with an acid gives off chlorine gas. Use one, rinse with water, and only then use the other.
It makes chloramine gas. The Washington State Department of Health lists coughing, shortness of breath, chest pain, wheezing, nausea and watery eyes, and in bad cases pneumonia and fluid in the lungs.
Leave the room and get to fresh air, then call the Poison Help line, 1-800-222-1222. It is free and confidential, 24 hours a day, 7 days a week. Call 911 if anyone has trouble breathing, has chest pain or passes out.
Not in the same bottle. Together they make peracetic acid, which the New Jersey Department of Health says can harm the eyes, skin and lungs.
No. Health departments say not to mix bleach with acids or other cleaners, and a washer full of water mixes them just as well as a bucket does. Keep vinegar out of the washer altogether, too. Maytag, a washer maker, says its acid can wear down rubber seals and hoses.
