Baking Soda and Vinegar: Cleaning Myths & Safety Risks
Few kitchen staples spark as much debate as baking soda and vinegar. One is a mild base, the other a weak acid—and when combined, they fizz with promise. But behind the viral cleaning hacks and wellness claims lies a chemistry lesson that often gets overlooked. Here’s what the science and the experts actually say about this popular pair.
Chemical reaction time: Instant fizz when mixed ·
Primary gas produced: Carbon dioxide (CO₂) ·
Common household uses: Cleaning, deodorizing, drain unclogging ·
Vinegar pH level: 2–3 (acidic) ·
Baking soda pH level: 8–9 (alkaline)

Six facts about the baking soda and vinegar chemistry, one pattern: the mixture neutralizes itself, leaving a nearly neutral solution that does little more than fizz.
The table below lays out the key chemical properties that explain why this combination underperforms as a cleaner.
| Property | Value |
|---|---|
| pH of vinegar | 2–3 |
| pH of baking soda solution | 8–9 (1 teaspoon in 1 cup water) |
| Resulting solution pH after mixing | Neutral (~7) – ineffective for cleaning |
| Carbon dioxide volume per reaction | Approximately 0.5 liters per gram of baking soda |
| Time to fizz after mixing | Less than 5 seconds, peaks at 10–15 seconds |
| Common cleaner alternatives | White vinegar alone, hydrogen peroxide, enzymatic drain cleaners |
Can you mix baking soda and vinegar to clean with?
Yes, you can mix them, but the result isn’t the powerhouse cleaner many online tutorials promise. The fizz you see comes from carbon dioxide gas released when the acid and base react. That bubbling action can help lift loose dirt, but because the two substances neutralize each other, the cleaning ability of both is greatly reduced. Brendid home-science blog explains that the reaction produces water and sodium acetate, a salt that has no detergent properties. Without surfactants, the mixture cannot effectively carry away grease and oil the way a dedicated cleaner can.
The fizz gives the illusion of action, but what you’re really seeing is two cleaning agents canceling each other out. For light deodorizing, it’s fine. For actual grime, you’ll need something else.
What should you not clean with baking soda?
- Glass and mirrors – Baking soda is abrasive and can scratch these surfaces.
- Aluminum cookware – The mixture can react with aluminum, causing discoloration.
- Marble and natural stone – The acid in vinegar can etch and dull the finish.
- Waxed surfaces – The abrasive powder can strip wax.
- Hardwood floors – Moisture from the mixture can warp wood and dull finishes.
Martha Stewart’s home-care team specifically warns against using baking soda on non-stick pans, gold-leafed ceramic, and marble. AA Plumbing SA licensed plumbing service adds that repeated baking soda use can leave residue that actually traps more debris over time.
How long can I leave baking soda and vinegar in the drain?
If you do use the mixture for a slow drain, Liquid-Plumr commercial drain cleaner brand recommends a specific sequence: pour boiling water first, then add baking soda and a water-vinegar solution, wait 5 to 10 minutes, and finish with another round of boiling water. The fizzing peaks within 15 seconds and stops after a few minutes—leaving it longer doesn’t increase cleaning power because the reaction is over.
Most plumbers advise against leaving the mixture in the drain beyond that short window. The pressure from confined gas, while mild, can stress older pipes or rubber gaskets. AA Plumbing SA licensed plumbing service notes that the mixture does not dissolve hair or grease—two of the most common clog culprits—so even a 30-minute soak won’t fix a blocked drain.
Step-by-step guide (if you still want to try)
- Boil a kettle of water and pour half down the drain.
- Add ½ cup baking soda directly into the drain.
- Mix 1 cup white vinegar with 1 cup hot water and pour it in.
- Cover the drain opening loosely—wait 5 to 10 minutes (the fizzing will stop after about 30 seconds).
- Flush with the remaining boiling water.
Liquid-Plumr commercial drain cleaner brand says this method is best for light odor control and minor gunk, not for full blockages.
The pattern: this mixture is a gentle home remedy, not a drain cleaner. For anything beyond mild odors, reach for a product designed to dissolve organic matter.
What do plumbers say about baking soda and vinegar?
Plumbers are nearly unanimous: save the baking soda and vinegar for science fair volcanoes, not your pipes. AA Plumbing SA licensed plumbing service explains that the fizz travels upward in an open drain instead of applying pressure where the clog is. The mixture does not scrub pipe walls or break down the sticky buildup inside them. In fact, the residue from repeated use can accumulate and make clogs worse over time.

Chemical drain cleaners aren’t perfect either. Top Notch Plumbing LLC commercial plumbing company warns that these products can generate intense heat that cracks toilets, softens PVC piping, and corrodes older metal pipes. They also release toxic fumes and can cause skin burns. But for sheer unclogging power, most plumbers recommend enzymatic cleaners or a mechanical auger over the homemade fizz.
If you have a slow drain, the baking soda and vinegar trick is a weak first step. Plumbers see it as a maintenance habit for mild odors—not a solution for real clogs. For homeowners, the safer bet is a enzymatic cleaner or calling a pro.
Why this matters: relying on baking soda and vinegar for drains can waste time and lead to bigger blockages. The residue left behind by the mixture can combine with grease and soap to form stubborn deposits that only a snake or auger can remove.
What are the drawbacks of using vinegar and baking soda for cleaning?
The biggest drawback is that the reaction neutralizes both ingredients, leaving mostly salty water. Brendid home-science blog points out that without an active acid or base, the mixture has limited ability to disinfect or cut through grease. Vinegar alone (pH 2–3) is a better disinfectant; baking soda alone is a fine abrasive. Together, they fizz briefly and then become ineffective.
Additional downsides include the risk of staining or etching certain surfaces (marble, hardwood, aluminum) and the fact that the mixture does not kill mold or bacteria at a level that meets safety standards. For heavy cleaning tasks, this duo underperforms compared to specialized products.
The catch: the fizzing reaction is fun to watch, but it’s a chemical dead end. For most household jobs, using vinegar or baking soda separately—or switching to a purpose-built cleaner—will deliver better results.
What does baking soda and vinegar do for your body?
Drinking baking soda and vinegar is a trend that medical experts strongly advise against. When ingested, the reaction can cause stomach upset, belching, and in larger amounts, metabolic alkalosis—a dangerous condition where the blood becomes too alkaline. Top Notch Plumbing LLC commercial plumbing company warns about chemical exposure; the same principle applies to internal consumption of reactive mixtures.
Does baking soda and apple cider vinegar help erectile dysfunction?
There is no reliable scientific evidence linking baking soda or apple cider vinegar to improved erectile function. The idea appears to come from anecdotal social-media posts that confuse harmless household ingredients with medical treatments. In short: the claimed benefit is unproven and likely placebo.
Is a teaspoon of baking soda every day good for you?
No. Consuming baking soda daily can disrupt your body’s acid-base balance, leading to nausea, muscle twitching, and more serious complications like stomach rupture. The medical consensus is clear: avoid regular ingestion of baking soda unless specifically prescribed by a doctor. Top Notch Plumbing LLC commercial plumbing company emphasizes the corrosive potential of such mixtures—inside the body, that risk is even greater.
Is vinegar and baking soda safe to drink every day?
No. While small amounts of vinegar are generally safe in cooking, combining it with baking soda creates a gas-producing reaction in your stomach that can cause bloating, pain, and in severe cases, damage to the esophageal lining. Drinking this mixture daily is not recommended by any health authority.
The trade-off: the internet may tout these ingredients as health tonics, but the biological reality is that they are a base and an acid that react to form an inert salt. Your body already regulates pH tightly—it doesn’t need kitchen chemicals to do the job.
Does baking soda help with weight loss?
Claims that baking soda boosts metabolism or burns fat are not supported by scientific evidence. Some proponents argue that it reduces stomach acid or alters body pH to promote fat loss, but these assertions contradict basic physiology. The body maintains a steady pH in the blood regardless of what you eat. Short-term water weight loss is possible due to the diuretic effect of high sodium intake, but this is neither healthy nor sustainable. Health authorities uniformly advise against using baking soda as a weight-loss aid.
The pattern: every “quick fix” that involves baking soda internally falls apart under scrutiny. The real consequence of following such advice is wasted money and potential harm to your digestive system.

Frequently asked questions
Can baking soda and vinegar whiten clothes?
Some people add the mixture to laundry to brighten whites, but the reaction neutralizes and produces only carbon dioxide. It offers minimal whitening compared to oxygen bleach or hydrogen peroxide.
Does baking soda and vinegar kill mold?
No. The mixture does not have enough acidity or alkalinity to kill mold spores. White vinegar alone (undiluted) can kill some surface molds, but baking soda added makes it less effective.
Is it safe to mix baking soda and vinegar in a washing machine?
Occasional small amounts are safe, but the fizz can interfere with water flow and the residue may build up in internal mechanisms over time. Use each separately for better results.
What happens if you mix baking soda and vinegar in a closed container?
The carbon dioxide gas builds pressure and can cause the container to burst. Brendid home-science blog specifically warns against mixing in a closed container due to explosion risk.
Can baking soda and vinegar remove rust?
The combination is not effective for rust removal. Vinegar alone can dissolve light rust, but adding baking soda neutralizes the acid and stops the process.
Does baking soda and vinegar unclog a toilet?
Plumbers do not recommend it. The mixture produces fizz that escapes without clearing the clog, and the pressure can damage toilet components if confined.
How often can you use baking soda and vinegar in a sink drain?
Occasionally (once every few weeks) for odor control is fine. More frequent use may leave residue that contributes to buildup.
For anyone tempted by a viral cleaning hack, the science is clear: baking soda and vinegar neutralize each other, leaving you with salty water and a false sense of accomplishment. For homeowners with a slow drain, the choice is simple—use an enzymatic cleaner or a plumber’s snake, or learn to live with the fizz and call it deodorizing. The real cleaning power lies in using each ingredient alone, where it belongs.
