Ever wondered what happens when you mix Comet and bleach? Spoiler alert: Nothing good. 

In fact, it's more like a recipe for a chemical disaster that could send you straight to the emergency room. 

Most people don't realize that combining these common cleaning products can create toxic gasses that are seriously dangerous.

In this post, I’ll explain why you should NOT mix Comet and bleach, and what to do if you accidentally mix them. Plus, I’ll also answer some FAQs at the end.

Can You Mix Comet And Bleach?

No, you should never mix Comet and bleach—or any cleaning products with bleach and ammonia.

Comet cleaners often contain ammonia or other reactive chemicals, and mixing it with liquid bleach (sodium hypochlorite) can create toxic gasses like chloramine or chlorine gas.

These vapors can seriously irritate your eyes, nose, and lungs and can even cause more severe respiratory issues if inhaled in large amounts.

So, mixing these two can quickly turn a routine cleaning job into a hazardous situation.

Dangers Of Mixing Bleach And Comet

The dangers of mixing Comet and bleach come from the toxic chlorine gas that gets released. 

Chlorine gas is no joke. Inhaling it, even in small amounts, can irritate your throat, nose, and eyes. If you’ve got asthma or other respiratory issues, it could trigger coughing, make it hard to breathe, or even set off an asthma attack. 

Inhaling a lot of it can seriously damage your lungs and airways.

This will lead to a lot of long-term health problems. 

So, you must never mix bleach with any cleaner that contains ammonia, including Comet.

What To Do If You Accidentally Mixed Comet And Bleach

If you've accidentally mixed Comet and bleach, every second counts. 

The toxic gasses released by the mixture can cause severe health problems, so you should act quickly and follow the right procedures. 

Here's a what to do if you've made this mistake:

#1 Do Not Inhale Fumes

The first thing to remember is that you do not want to breathe in any of those fumes.

As soon as you realize you've mixed Comet and bleach, the most important thing is to hold your breath and get away from the area. Chlorine gas and chloramine are really dangerous like I said.

If you're in a small room or closed space, it gets even worse.

So, if you’ve already inhaled some of the fumes, don’t panic—just get out of there and into fresh air as fast as you can.

If you're feeling dizzy, nauseous, or have trouble breathing, don’t hesitate to seek medical attention.

#2 Open All Windows

Once you've held your breath and moved away from the immediate area, the next step is get the fumes out of the house. 

Start by opening up every window and door in the area. Seriously, all of them. You need to get some air moving through the room to help clear out the gas. 

If you can create a cross breeze (open windows on opposite sides of the room), that’ll help speed things up. 

If you're in a room with no windows, or the windows won’t budge, look for other ways to get air circulating—maybe use a door or even a vent. If you’ve got a fan, now’s the time to turn it on and blow the fumes outside. 

But, pro tip: don’t blow the fumes into other rooms or towards people or pets. You want those gasses out of the house, not into other spaces.

#3 Leave The Room

After you’ve got the air moving, don’t stick around trying to clean up the mess just yet. 

Leave the room. Don’t try to fix the situation by neutralizing the mix or scrubbing the floors. You need to get out and avoid more exposure. 

Close the door behind you to keep the gasses from spreading. 

If there are kids or pets in the house, get them out of the area ASAP. The fumes can be especially dangerous for little ones, older people, and anyone with breathing problems. 

Once you're out, stay out until you’re sure the air has cleared.

#4 Clean Up Afterwards

Once the room is safe to re-enter and the air’s cleared out, it’s time to clean up.

But proceed with caution - you definitely don’t want to touch anything without protection. 

Slip on some gloves, a face mask, and carefully dispose of any contaminated cleaning materials, and give the area a thorough cleaning with soap and water. 

Make sure to rinse everything well to get rid of any leftover residue. 

If you're not sure how to safely clean up or you're feeling a bit overwhelmed by the situation, it might be worth calling in a professional cleaning service—especially one that's experienced with hazardous materials. 

Bottom Line

Mixing Comet and bleach is a recipe for disaster. The toxic gasses released by the mixture can cause severe health problems, including respiratory issues and chemical burns.

If you accidentally mix these two substances, follow the steps I outlined above. 

Remember: never mix cleaners unless you're 100% sure it’s safe. 

Stick to the instructions on the labels, and you’ll save yourself a lot of headaches.

FAQs

Does Comet Have Ammonia In It?

Yes, some Comet products do contain ammonia, especially the liquid cleaners. 

However, it depends on the specific product (ones labeled as "with bleach," do not contain ammonia), so it's always a good idea to check the label for the ingredients.

What Can You Mix With Comet Powder?

Comet powder is designed to be used on its own or mixed only with water. You can mix it with some water to create a paste or cleaning solution that’s effective for scrubbing surfaces like sinks, tubs, and countertops.
