“[Mixing] bleach and vinegar—or any acid or acidic product, such as toilet cleaner—[creates] chlorine gas," says David A. Walla, PhD, lead scientist for Defunkify. "This can lead to coughing, breathing problems, burning, and watery eyes."
While cleaning vinegar can be combined with some other cleaners, like dishwashing liquid, never mix cleaning vinegar and chemical cleaners, like chlorine bleach, which, when combined, produce toxic fumes.
So, while you can use baking soda, hydrogen peroxide, and bleach on their own for cleaning purposes, we recommend that you avoid mixing them with vinegar. However, if you have accidentally mixed either of these, it is best to dispose of the mix outside immediately.
To safely and inexpensively clean your toilet bowls, pour a generous glug of vinegar, followed by a heavy sprinkling of baking soda, into the bowl. While the mixture is bubbling up, scrub the bowl (get under the rim, too). Let it soak for 30 minutes and flush. That's it.
Don't mix: Bleach and toilet bowl cleaner
“Some people may add bleach to the [toilet] bowl, but the combination of bleach with the acid from a toilet bowl cleaner releases chlorine gas,” says Marshall. “Even at low levels, it irritates eyes, nose, and throat and causes coughing and breathing problems.
You should never clean with these two ingredients combined. Mixing chlorine bleach, which contains sodium hypochlorite, with any type of acid like vinegar creates chlorine gas, a dangerous chemical that's deadly in high volumes.
Vinegar and baking soda produce that oh-so-familiar chemical reaction that powers through buildup and loosens tough stains. While it might seem like it's chewing its way through grime, it's not powerful enough to damage the porcelain finish of the toilet bowl.
Vinegar will not damage your toilet in any way if it's left in your toilet overnight. In some cases, leaving the vinegar in your toilet overnight is recommended to get the best cleaning results. No matter what material your toilet is made from, the vinegar will not damage your toilet.
Hydrogen Peroxide and Vinegar
While these two chemicals can be used in succession as a cleaning duo, do not mix them together. “Combining these two creates peracetic acid or corrosive acid, an irritant that, in high concentrations, can harm the skin, eyes, throat, nose, and lungs,” says Bock.
Rinsing is not necessary! If you're simply using a vinegar and water solution to wipe and disinfect, you won't need to rinse. However, if there's also plenty of dirt and grime you're wiping away, you may also want to rinse with some extra water.
Combined, baking soda and vinegar can sometimes clear a clogged sink, but in many cases, they can also take care of a toilet clog. However, to avoid a small eruption all over the bathroom floor, you'll want to measure them very carefully.
As a general rule, most natural cleaning experts suggest mixing one part vinegar to one part water. These recommendations typically rely on distilled white vinegar as the cleaning element. If homeowners are using cleaning vinegar, they may want to add a little more water to achieve a similar amount of acetic acid.
The only difference between cleaning vinegar and the distilled white vinegar is their levels of acidity. White vinegar is usually 95 percent water and 5 percent acid. By contrast, cleaning vinegar contains up to six percent acid and is around 20 percent stronger than regular white vinegar.
Pour a half-cup of hydrogen peroxide into the toilet and let it sit for 30 minutes. Use your toilet brush to scrub the stains. Add a sprinkle of baking soda and scrub again if the stains persist. Turn on the water and flush away stains and germs.
Turn off the water to the toilet, flush the toilet to minimize the water in the bowl, and pour in a gallon of vinegar to remove scale and mineral deposits. Leave the vinegar in the toilet for 24-48 hours. This may improve the flushing.
Citric acid
More importantly, it's probably even more effective than vinegar for getting rid of that brown stain in the toilet. Simply pour a kettle of almost boiling water into the bowl, follow up with 250ml of citric acid, and leave it for some hours – preferably overnight. The next day, scrub and flush.
"The biggest don't when it comes to toilet tanks is bleach—do not use bleach or products containing bleach inside the tank, as it can corrode the internal parts of your toilet. If you are aiming to remove tough stains from the tank, I also recommend white vinegar diluted with water."
To remove tough stains, add the baking soda and vinegar mix to your toilet and then allow the solution to sit in the bowl for up to 30 minutes. During that time, the chemical reaction between the sodium bicarbonate and vinegar will work to eat away at those stubborn hard water stains.
No. The two products have different ingredients and, as is true with any cleaner, should never be mixed with another cleaner.
The combination of dish soap and vinegar is highly effective for a few different reasons. They're both excellent at breaking down tough grease and grime, but vinegar alone will simply run off of most surfaces, and dish soap is too thick to use on its own.
A chemical reaction between the vinegar and the baking soda produces bubbles of carbon dioxide gas. The dish detergent in the vinegar helps the bubbles last longer than they would with just vinegar and baking soda.
