What Happens If You Mix Dish Soap and Baking Soda?

Dish soap and baking soda creating foamy bubbles

Introduction: a curious kitchen-counter experiment

Put two humble household staples together—dish soap and baking soda—and you get a combination that shows up in cleaning hacks, stain remedies, and a few daring TikTok videos. The pair looks like the start of a small kitchen lab, but what really happens when they meet?

This post takes the guesswork out of the experiment. We’ll peek at the gentle chemistry, the useful cleaning tricks, and the small list of surfaces where you should think twice before scrubbing.

The short answer

Mixing dish soap and baking soda doesn’t produce dramatic chemistry. There’s no big fizz, no toxic gas—just a mildly alkaline, soapy paste that’s both abrasive and good at cutting grease.

In other words: it’s a clever, mostly safe cleaning combo—but not a magic potion. The real power comes from texture (scrubbing), mild alkalinity, and the grease-busting surfactants in the soap.

What’s happening, scientifically

Baking soda: more than a rising agent

Baking soda is sodium bicarbonate (NaHCO3). In water it dissolves to give a slightly basic solution, which makes it helpful for neutralizing mild acids and neutral-smelling odors.

Alone it’s a gentle abrasive—useful for scrubbing, but not so harsh that it eats through most finishes.

Dish soap: surfactants and foam

Dish soap is mostly water plus surfactants (the grease-cutting molecules), a little fragrance, and sometimes a mild pH adjuster. The surfactants lower surface tension so grease lifts off surfaces and rinses away.

Dish soap also traps air and forms bubbles easily, which makes a baking-soda-and-soap mix feel foamy even if no gas is produced chemically.

Put them together

When you stir baking soda into dish soap you make a paste where:

  • baking soda provides abrasiveness and mild alkalinity,
  • dish soap supplies grease-cutting surfactants and foaming action,
  • and water (from the soap or added separately) dissolves the bicarbonate so it can do its deodorizing and cleaning work.

There’s usually no chemical reaction that releases gas unless an acid is present. If you want fizz, you need an acid such as vinegar—then you’ll get the classic baking-soda eruption. For a deeper dive into fizzing mixtures that do bubble, see experiments like mixing baking soda with hydrogen peroxide.

Why people use this mix

The combination is popular because it’s practical and forgiving. Here are the common reasons it turns up in cleaning recipes:

  • It makes a gentle but effective scouring paste for pans, sinks, ovens, and grimy surfaces.
  • The soap helps dissolve grease while baking soda scrubs and neutralizes odors.
  • It’s inexpensive, low-toxicity, and uses ingredients most people have at home.

How to use it—safe cleaning recipes

All-purpose scrubbing paste

Make a thick paste with about 2 parts baking soda to 1 part dish soap. Add a splash of water if it’s too dry. Spread on the stain, let it sit 10–20 minutes, then scrub and rinse.

Great for: stainless-steel sinks, grimy oven racks, cast-iron (sparingly), and ceramic stovetops.

Tough grease on pots and pans

Sprinkle baking soda on a scorched pan, add a few drops of dish soap, then pour in hot (not boiling) water. Let the pan soak for 15–30 minutes before scrubbing. The soap loosens grease while the soda helps lift burnt bits.

Bathroom grout and tile

Apply the paste to grout, let it sit 10–15 minutes, then scrub with a toothbrush. The abrasive action lifts grime and the soap carries it away when you rinse.

Spot stain pre-treatment

For fabric stains, try a tiny dab of diluted soap followed by a sprinkle of baking soda. Rub gently, then launder as usual. Test on a hidden seam first—some dyes or delicate fabrics may react poorly.

Limitations and when it won’t help

If you’re dealing with a chemical stain or biological contamination (mold, blood, pet urine), you may need specialized cleaners or a disinfectant. This paste cleans and deodorizes but isn’t a disinfectant the way bleach or alcohol-based cleaners are.

Also, if you need real fizz to lift stubborn residue (like a vinegar reaction), plain dish-soap-and-baking-soda won’t produce strong bubbling on its own. For foamy chemistry tricks, consider mixtures specifically designed to release oxygen or carbon dioxide—there are safe posts about using baking soda with hydrogen peroxide for that bubbly lift.

Safety and surface warnings

The mix is generally safe, but a few caveats are worth keeping in mind before you scrub everything in sight.

Watch delicate surfaces

Abrasives can dull and scratch. Avoid using baking-soda scrubs on polished marble, natural stone, or soft metals like aluminum. On those surfaces, a milder soap-and-water clean is a better bet.

Avoid mixing with strong chemicals

Don’t mix this paste with bleach, ammonia, or acidic cleaners—combining household chemicals can create hazardous gases or reduce cleaning power. If you’re unsure, follow label warnings and keep mixtures simple. For a clear example of a dangerous household pairing, our explanation of why mixing bleach and vinegar is risky is a good read.

Skin, eyes, and pets

The paste is low-toxicity, but avoid prolonged skin contact if you have sensitive skin. Rinse hands after use and keep cleaning mixtures away from curious pets and small children.

Tips for better results

  • Let the paste sit for a while on stubborn stains; time often matters more than elbow grease.
  • Use warm water to help the soap dissolve grease faster, but don’t use boiling water on plastic or delicate finishes.
  • Test on a hidden spot before applying to visible finishes like decorative enamel or painted surfaces.

Alternatives and when to pick them

Sometimes another combination does the job better. For fizzing oxygen lifts and whitening, baking soda plus hydrogen peroxide can outperform plain soap. If your stain is acid-reactive or you need a disinfectant, follow manufacturer recommendations rather than improvising.

If you’re curious about other kitchen-cleaning combos that work (and how they behave), there are friendly posts that explain what happens when two common items meet—like toothpaste and vinegar—and why those mixes can be surprisingly useful.

Quick troubleshooting

  • Paste won’t scrub off grease? Add a touch more dish soap or let it soak longer.
  • Surface looks dull after scrubbing? You may have used an abrasive on a sensitive finish; try a polish recommended for that material.
  • Need true deodorizing power? Baking soda helps, but for strong odors consider a deeper-cleaning routine or specific odor-neutralizing products.

Final thoughts

Mixing dish soap and baking soda is a dependable, low-risk cleaning trick. It’s practical, pleasantly unspectacular, and surprisingly versatile around the kitchen and bathroom.

Think of it as a friendly, everyday tool: not a chemical spectacular, but a quietly useful pair that gets a lot done. If you love small, safe home experiments, there are related posts that explore fizzier mixtures and household chemistry in more detail.
