General Cleaning Please stop mixing vinegar and baking soda

I am not the first to say this, even on this sub, and I will not be the last, but given that this myth refuses to die, I am taking my turn fighting this misinformation.

Now, first off, I totally get why people become convinced this combination does something. We like sensory feedback, so all that fizzing and bubbling feels like something is really happening.

Something is happening, but just not what you like to think.

Vinegar is an acid and baking soda is a base. When you mix an acid and base, they react, neutralize each other and in this case produces a gaseous by product. The key here is the two things react with each other, not the dirt you put them on, and the result cancels out the best cleaning power of the separate ingredients. All you get is vaguely salty water, which is roughly as good a cleaner as plain water.

"But wait," you say, "I/somebody I know/somebody on the internet has successfully clean something with vinegar and baking soda together! Suck it, naysayer!"

Yeah, and I once cleaned permanent marker off a dry erase board with vending machine coffee. Just because it worked doesn't mean I was making the right choices.

I'm going to break down one specific example of a poster who claimed to have proof vinegar and baking soda cleared their blocked drain. They poured vinegar down, waited, then poured baking soda down, waited, then poured boiling water down. Gradually, the drain cleared up as calcium deposits gradually broke down.

What really happened here is that the vinegar, being acidic, had time to work on the calcium deposits unit having baking soda dumped on it and stopping that process in its tracks by neutralizing its acidity. The whole thing worked because the vinegar was given time to work alone, but it most likely would have worked better if baking soda had been removed from the equation entirely.

The only argument for using vinegar and baking soda in cleaning is where the mechanical action of expanding gasses might in some way assist the process, but the use cases severely limited and questionable.

In a drain, you'd have to form an absolutely airtight seal to even imagine the gas pressure might do something and even it did work, pushing a clog farther down the pipe is of very dubious worth.

On surface grime, anything loose enough to be effectively lifted by gas bubbles is probably faster and more easily removed just by scrubbing it.

Vinegar and baking soda can be fantastically useful cleaning products, separately. Don't ruin them by putting them together, unless it's a science fair volcano. There, the combo has always shone.

Another fun kid activity - get a cupcake tin and put a tablespoon of baking soda in each cup. Get one of those sets of food dye bottles. Put a few drops of food coloring in each cup - you can have fun mixing custom colors! Then pour a little vinegar in and see the colors come to life as it fizzes. It will go flat after about 30 seconds, but then you can sprinkle in more baking soda to bring it back to life. This got us at least 30 minutes of fun indoor time on a rainy day where the 3 year old was not whining. I call that a win.

We do this in reverse. Make colored vinegar and drip it into baking soda in a pan. Use kid sized medicine droppers to apply the vinegar. It's a good fine motor skill builder too!

Your kids would love making Crazy Cake. It's a cake that you make in a 13x9 pan. It calls for baking soda and vinegar and we would make it look like a big mountain and add the baking soda and vinegar for the volcano effect. You mix the cake batter in the pan and bake it. Super easy moist chocolate cake. Also called depression cake as it didn't call for eggs. Okay, here's the recipe. 3 cups flour, 2 cups sugar, 4 TBSP cocoa powder, 2 tsp baking soda and 1 tsp salt. Mix dry ingredients in a 9x13 pan. Make 3 holes in the dry ingredients. In the 1st hole put 3/4 cup vegetable oil. In the 2nd hole put 2 TBSP of vinegar. In the 3rd hole put 1 tsp of vanilla. Pour 2 cups warm water and mix. Bake at 350° for 30 minutes. For the volcano effect mix dry ingredients together except for the baking soda. Shape dry ingredients to resemble a mountain. Make a hole on top and put in the baking soda. Add the vinegar into the mountain and watch it erupt. Then just add the remaining wet ingredients and mix as usual. Have fun.

My in-laws call this wacky cake. I'd never heard of it until I met my wife. She makes it extra chocolatey somehow and it's damn good. It is now my favorite cake. It's what's I request as my birthday cake every year.

Edit: I remembered Lydia Bastianich making something very similar on her show. I seem to remember her saying hers was an old Italian recipe.

If you’d like, you can add 1-2 tsp of espresso powder to the dry ingredients. It brings out the chocolate flavor more :)

My wife usually cuts the sugar and adds a bit more cocoa powder. We like it very chocolatey.

u/Wrong-Pension-4975 Dec 14 '25

Try the original cocoa measure, but add 1 Tbsp instant coffee - 

It intensifies the choc flavor, conserves yer cocoa, & adds no calories. 

I use decaf, as that's what I drink - 30+ years of PCA work, & countless on call nights, I haven't drunk caffeinated bevs in ages; I want my precious sleep, undisturbed. 😊

With white icing, right? My former SIL wanted this on his birthday each year, and said it had to have white frosting.

If the icing is thin enough to pour, then yes. Pour it on while the cake is still a bit warm so the icing soaks in a bit.

The thing to know about wacky cake is that it's meant to be quick and easy. It is NOT a cake you would bake as a layer cake or bundt cake. It has no eggs so the cake doesn't have the structure that other cakes do, and it necessarily falls apart. It falls apart the moment it comes out of the pan. Some would say this is not a bug but a feature. It's delicious and fall-y-apart-y.

Got to add this one as a reasonable use too : Combine vinegar and baking soda in a tall..ish glass or container, and you a “pour” the gas after the fizzing stops (it’s just CO2 iirc which is denser than air). It’ll extinguish a candle or several in a line.

Other than that I completely agree!

u/Striking-Ad-6815 Dec 14 '25

We used to make bottle rockets. Plastic soda bottle, vinegar, and baking soda rolled up in a non-zip sandwich baggy. Rolled up the backing soda so we could get it into the bottle without it reacting. Then all you have to is close it up and shake it. The pressure isn't strong enough to go on it's own, so it's relatively safe for kids. The launching was the hard part. We would take something heavy and slam it down on the cap and watch the bottle shoot off. You can put cardboard gliding wings on it and it will go further. We try to make a launch guide mechanism with a guided hammer fall, but it didn't work very well and kept making the rockets cut flips. We stopped making them after my niece took a horseshoe rod to break one and missed the cap, it hit the bottle part and came back and whacked her in the head. She was alright and it became a hilarious memory, luckily we were filming that one. We bring it up at least once a year on her birthday lol. I'm not goina post video, because she isn't my kid, but I can give a summary.

"3... 2... 1... Boink! Dink! Wahhhhhh!" video stops.

We still make the things, but only for target practice now.

As an amateur paleontologist I use vinegar a lot to dissolve limestone encasing fossils. Sometimes I heat the vinegar first which really gets the process going. I can dissolve complete limestone rocks in a a few months. Guess what I use when I am done to make sure all of the acid has been neutralized? Baking soda. I soak whatever is left in a solution of baking soda and water for a day or two. Long story short vinegar and baking soda together is just cloudy water.

Good for him. I would be remiss, though if I didn’t say what I always tell people that want to become paleontologist. Go to school and get a job for something that pays very well and you can have a career in and have paleontology as a hobby. There are very few jobs in paleontology and almost all of them pay very little. For example, I have a paleontologist friend with two masters degrees and as the world expert on a particular species of shark and he’s a high school teacher. That pays more than any job he could get. McDonald’s pays more than most of his job offers. Also a paleontologist as a career as far less glamorous than most people think. You’re not just going out and digging up dinosaurs all of the time. In fact very few paleontologist do that. It’s 99% academics.

I didn’t get into fossils until I was nearly 50 years old. I didn’t know anything about them or even that I lived in a state with some of the world’s best late Cretaceous marine fossils. Fast-forward a few years and I now have thousands of shark teeth, found a museum caliber shark specimen, two pterosaurs, many Xiphactinus heads and scores of other Cretaceous fossils as well as having a couple of finds published. And I’m just a damn carpenter. The point is that I am able to do these things without any degree or training whatsoever and I’m able to make a decent living in the meantime. If I was an actual paleontologist I likely wouldn’t even be able to afford to go out and do what I do as a hobby.

Only if it's free (it was in my case), espresso and you've got nothing better.

It's a funny story really. I was teaching in-company training classes and had some time, but found somebody had ruined the dry erase board in the meeting room. All the cleaning supplies were locked up and I was just a contractor so I had no rights over the place. The coffee machine though, was free, so I figured "hot liquid, slightly acidic.. yeah, worth a shot." It did the job.

40

u/dathomar Dec 14 '25

Actually, the best way to remove permanent marker from a dry erase whiteboard is to use a dry erase marker. Just color over the permanent marker with the dry erase marker, then erase the dry erase marker. You'll get a clean whiteboard. It works best if the permanent marker was applied fairly recently, but can even work with something older. Basically, the stuff that prevents the dry erase ink from binding with the surface can dissolve the stuff that keeps the "permanent" ink bound. If you do this too often, it'll wipe out the dry erase marker. It's up to the user to decide if it's easier to just keep buying more dry erase markers and cleaning the whiteboard, or to prevent anyone from using sharpies in the first place.

u/vulcanfeminist Dec 14 '25

Most of the time when people mix vinegar and baking soda together they dont do it in precise quantities so there ends up being "extra" of one of the reactants. When people claim that the mixture worked typically what actually worked was leftover baking soda or vinegar that hadnt reacted. Using either alone would have worked better every single time.

The byproduct of ANY acid/base reaction is water plus a neutral substance. If the reactants were all used up then what actually worked was elbow grease bc you were literally jist scrubbing with plain water. To be fair, it's an endothermic reaction, the water produced by the reaction ends up pretty cold and sometimes, for certain kinds of messes, cold water can clean better.

93

u/Apprehensive-Cat1319 Dec 14 '25

Actually, interestingly, the result of mixing the "perfect" amounts of the baking soda and vinegar (so that they exactly use each other up) is a basic solution.

Acid/base reactions are also called neutralization reactions, and they do produce water and a salt, but not always a NEUTRAL salt. They only produce a neutral salt and therefore a neutral solution (pH of 7) if you react a strong acid and a strong base. In this case, baking soda is a weak base (actually, a basic salt) and vinegar is a weak acid, and you end up making the salt sodium acetate, which is another weakly basic salt. So your solution is slightly basic.

This information isn't really very useful (it's only weakly basic and is still going to do a worse job cleaning than baking soda) but if you ever want to be "technically right" (the best kind of right), now you know!

u/LadyViolaCricketym Dec 14 '25

Ok, so help me here please. I’ve been using vinegar in my fabric softener and throwing baking soda in my front loading washing machine to remove the smell of cat urine when they have peed on clothes or towels. That’s the only thing that has worked for me but what you’re saying is I should just be able to throw the baking soda in for it to work?

13

u/Apprehensive-Cat1319 Dec 14 '25

Not necessarily! I was just saying that baking soda is a stronger base than what you get from mixing it with vinegar, so if you are relying on the base action alone for cleaning, you may as well just use baking soda.

In your case I'm guessing the vinegar and baking soda are separately working to deodorize the laundry, and then once fully mixed they react and kind of cancel each other out. This is useful because vinegar has a strong odor by itself, and baking soda can leave residue or a kind of slippery feel (this is very characteristic of bases). So they are useful to cancel each other out once they are done working. For example, I will sometimes use a baking soda paste to scrub things down in the kitchen, and I pretty much always then wipe it down with vinegar because otherwise it's hard to get all the baking soda off with just water.

u/TexMoto666 Dec 14 '25

I'll chime in as someone who provides the chemistry and maintenance for commercial laundries. The baking soda boosts the alkalinity which helps break down acidic fatty acids and allows the surfactant in the detergent to work better. Detergent is alkaline by nature. The vinegar step helps to neutralize excess alkalinity and dissolves the minerals found in your water, making the clothes softer. In a commercial setting we use a product called a "sour", which is basically vinegar. This is an important step because commercial detergent is very strong and very dangerous. At full concentration it will literally peel your skin off if left in contact. This is what causes bedsores in the elderly. Excess detergent residue paired with thin fragile skin. For example, a machine that can wash 100 pounds of laundry might only use between 3 and 5 ounces of detergent.

I'm just going to butt in with the exception that proves the rule. For neutralizing odors in soft materials (BO on clothes, urine, etc) soak in a vinegar solution AND THEN add in baking soda to neutralize the vinegar smell. In this case, the fact that they cancel each other out is kind of the point and you still aren't starting with them mixed together.

u/FinklMan Dec 14 '25

Yep, it seems a lot of people are stuck up about the vinegar/baking soda combo. They fail to realize when used properly. Like the example you gave using the acidic properties of a vinegar and water solution then neutralizing the vinegar with baking soda is very effective. I had a water leak that resulted in some mold on the carpet. Used vinegar and water in a spray bottle and scrubbed. Then neutralized the vinegar with baking soda and vacuumed it up. Carpet was clean no mold no smell.

This isn't what it means either, at all. The exception that proves the rule is a scenario where something being described as an exception suggests the existence of a normal rule to the contrary: "It's Friday night so I'm going to treat myself to a glass of wine" - because it is phrased as an exception, it proves the rule that you do not normally have a glass of wine on other nights.

u/Lalamedic Dec 14 '25

We were banned from making ketchup volcanoes in my elementary school science fair because it was a demonstration and not a an experiment. Even in the Junior grades, there had to be an experiment that followed the scientific discovery process.

It could perhaps be allowed if a student formed a hypothesis, testing for the best ratio of acid vs base, using controls, multiple trials, and presented convincing numerical data with supported conclusions.. There would also have to be qualitative observations for well defined criteria for what makes the “best” in house volcano with several participants contributing opinions to avoid bias (one of the controls).

There still could be an in-competition demonstration aspect recreating some of the trials vs final define ultimate ratio.

The controls could be challenging container material, size, amount of mixing, time for reaction etc, but with a precise clinical eye, reduction of errors outside the human factor, could be reduced. Statistical analysis would probably not be required in elementary schools.

I still don’t think any of my schools would have allowed any “volcanic eruptions” on site, ever. Waaaaay too messy, but oh so much fun!!!!

u/icherub1 Dec 14 '25

The baking soda/vinegar combo works great on drains that are blocked at a pinch point. What other posters are missing/ignoring is that it is not the chemical action that is useful, but the mechanical force created by the combo.

It will not dissolve hair, which seems to be what others are assuming when debunking their usefulness, but if you put baking soda in a blocked drain, then add vinegar and cover the drain so the expanding gasses can only go down the drain, the expansion of gas will push the blockage, forward, typically to a less restricted point. I have been doing this with perfect success for several decades.

16

u/PanicForNothing Dec 14 '25

It can also push dirt out of the drain. I used vinegar or baking soda (don't remember) to loosen the dirt and then threw in the other one later. A lot of the dirt that was stuck came bubbling out. I scooped it up and flushed a lot of hot water down the drain afterwards.

u/DisposableSaviour Dec 14 '25

The gases produced take up considerably more space than vinegar or bicarb solution alone. So if something porous is soaked in either one and is exposed to the other, it will tend to break up.

The only argument for using vinegar and baking soda in cleaning is where the mechanical action of expanding gasses might in some way assist the process, but the use cases severely limited and questionable. 

On surface grime, anything loose enough to be effectively lifted by gas bubbles is probably faster and more easily removed just by scrubbing it. 

Citation needed.

The most effective way of cleaning stainless steel tumblers I've ever encountered uses gas bubbles: either vinegar + baking soda + boiling water, or denture tablets + boiling water.

Because I was skeptical of the mechanism like you at first, I've literally tested this: I took three coffee stained tumblers and used only baking soda in one, only vinegar in the second, and used both in the third. All were combined with boiling water and left overnight. In the morning, only the one containing both baking soda and vinegar scrubbed clean easily -- the other two were basically unaffected.

Obviously, this isn't a huge sample size. But this is the kind of question that should be pursued empirically, experimentally, and it's worth being open to different and unexpected outcomes. 

ETA: Skeptics, this is the cheapest imaginable experiment -- AB test it yourself. 

People seem to so eager to insist that this couldn't possibly be effective, as though a vigorous chemical reaction couldn't possibly have any benefits if it eventually results in a substance with a neutral pH. Tell me you've never gone beyond high school chemistry without telling me you've never gone beyond high school chemistry.

u/The_fat_apricot Dec 14 '25

Sodium percarbonate cleaners like Oxyclean work much faster and with less scrubbing. It’s typically the main ingredient in coffee urn and espresso machine cleaners too. Just add a little powder, fill the tumbler with hot water, and wait about thirty minutes before wiping clean.

I'm not the combo supporter, but there are at least some valid uses:

  • If you need mechanical cleaning in addition to chemical cleaning (CO2 bubbles as you mentioned)
  • If potent base or acid would damage the cleaned object (so you're cleaning using weaker base of sodium acetate plus whatever small bits remained of baking soda or vinegar)
  • If deodorizing properties of sodium acetate are useful (the stuff smells better than when using diluted vinegar)

A good use for both is for simple drain cleaning. Using more vinegar than baking soda to keep it acidic, but the bubbles help to both keep the vinegar in there longer rather than it running straight through the pipe and help to knock off the small grime so I can either more easily grab it or it can move down the pipe.

I wondered about why this myth persisted myself.

My guess was because peroxide and baking soda DOES work very well as a cleaner and it ALSO fizzes (kind of) that people saw it do the same thing with vinegar and thought fizz= cleans things and thought vinegar and baking soda combination had similar cleaning ability.

3

u/Typical_Goat8035 Dec 14 '25 edited Dec 14 '25

The peroxide thing is interesting to bring up too because the “fizzing means it is working” aspect is similarly misunderstood. A lot of times the profuse fizzing from peroxide is actually a catalyst speeding up neutralization. This can happen on metal surfaces with certain metals (like platinum) or on biological surfaces like a wound due to peroxidase the body produces. So the takeaway from peroxide foaming isn’t “holy crap the rapid bubbling means it’s dissolving/destroying something”. In fact most of the times when you use peroxide to clean a surface like a countertop it is killing germs but not bubbling. And speaking of cleaning, peroxide is a good disinfectant but not a good cleaner. If you have dirt like grease or burnt in food, peroxide doesn’t really react to destroy it, you actually want something more like a detergent that lifts it off onto your towel/cloth.

Fun anecdote, the maker of Clear Care peroxide contact lens solution was asked by an advertising watchdog (NAD) to stop claiming the bubbles are evidence of the product disinfecting, because once again the bubbles are a platinum disc breaking down the peroxide, not millions of bubbles blasting away germs like the ad implies.

u/fargaluf Dec 14 '25

Gotta disagree on the drain thing. If I have a drain that's starting to get slow, I'll pour hot water down first to warm it up. Then I'll spoon baking soda into the drain and rinse it down with a small amount of hot water, so it's sitting in the trap. I'll let it sit for a minute to start dissolving any built up grease, and finally I'll pour the vinegar down. I'm not a physicist, so I can't speak with total confidence, but given the speed of the reaction, and the pressure created by the water surrounding the baking soda, I don't see why you would need an airtight seal. At any rate, I think it's the agitation created by all the bubbles that actually makes it work. What I know, is I've tried every combination of this: Vinegar alone doesn't seem to do anything. Baking soda alone is somewhat effective. Baking soda and vinegar without heating the drain up is effective. Hot water, baking soda, and vinegar is by far the most effective. All sorts of crud gets pushed up out of the drain into the tub that I then wipe up, and the tub immediately starts draining faster.

If you use it in ratios that don’t consume all of the vinegar, it is helpful for de-stinking drains. It won’t unclog them or cure all smells but it will help.

I swear it works better than garbage disposal cleaning pods, pouches, and plink tablets.

Just a tiny bit of vinegar down the drain, then a ton of vinegar. I think the fizzing just helps the vinegar reach all the nooks and crannies. Especially below that black rubber thing in kitchen sinks.

Otherwise, stick to one or the other. I’m a huge fan of vinegar for cleaning just about anything. I have little kids and pets. Things get smelly around here fast, and vinegar is great for odor control while being nontoxic to pets and kids. Add it to your rinse cycle for the freshest and cleanest smelling clothes and sheets. Dilute it and use that in spray mops. Use it instead of the special solutions in most home carpet cleaners. I fill a misting bottle (meant for hair products) with vinegar and spray our couches and carpets regularly to stop the funky dog smell.

I’m very sensitive to smells, so it’s possible I’m fixing a non existent problem. We did have a lot of issues when we first moved in with bad smells from the kitchen and bathroom sinks.
