You’re standing at the sink, staring at a lasagna pan that looks like a scorched-earth battlefield. Soap isn't doing it. You’ve scrubbed until your forearm hurts, and that crusty, orange cheese ring isn't budging an inch. It's frustrating. Most people just reach for more chemical-heavy degreasers or, worse, throw the pan away in a fit of rage. But honestly, the answer has been sitting in a little orange box in your pantry for about 150 years. Using baking soda for cleaning dishes isn't some "vintage" trick your grandma used because she had nothing else; it's literally chemistry in action.
Sodium bicarbonate is a mild alkali. When it hits water, it creates a solution that can dissolve grease and neutralize those acidic food smells that linger on plastic Tupperware. It’s cheap. It’s safe. It works.
The Science of Why This Stuff Actually Works
Let’s get nerdy for a second. Baking soda is a physical abrasive, but a gentle one. Think of it like a microscopic sandpaper that dissolves before it can actually ruin your expensive finishes. According to material scientists, baking soda has a Mohs hardness scale rating of about 2.5. For context, your stainless steel sink is around a 5 or 6. This means you can scrub away without worrying about deep scratches, which is why it's the gold standard for delicate surfaces.
It’s also an amphoteric substance. That’s a fancy way of saying it can react as either an acid or a base. If your leftover chili is acidic, the baking soda neutralizes it. If you’ve got something basic, it does the same. Most stuck-on food is acidic, so the alkaline nature of the soda breaks down the proteins and fats. It’s basically a molecular crowbar.
Dealing with the Nightmare: Burnt Pots and Pans
We've all done it. You walk away from the stove for "one minute" and come back to a blackened mess. If you try to scrape that off dry, you'll destroy the pan. Instead, try the simmer method. Fill the pot with an inch or two of water, toss in a generous half-cup of baking soda, and bring it to a boil.
The heat speeds up the reaction. You’ll see the black bits start to flake off and float to the top like little charred icebergs. Once the water cools down, you can usually just wipe the rest away with a sponge. No sweating required. For those really stubborn, polymerized oil stains on the bottom of sheet pans? Make a thick paste. Mix the soda with just a few drops of water until it looks like frosting. Slather it on. Leave it overnight. By morning, the oxygen in the mixture has worked its way under the grease.

Plastic Containers and the "Stink" Factor
Plastic is porous. You might think it’s solid, but on a microscopic level, it’s like a sponge for smells. This is why your Tupperware still smells like onions three washes later. Dish soap is great at removing surface oil, but it doesn't always reach into the pores of the plastic to neutralize the odors.
Baking soda is different. Because it’s a natural deodorizer, it pulls the scent out. I usually suggest a "soak and sit" approach here. Fill the container with warm water and two tablespoons of soda. Let it hang out for an hour. If the stain is also an issue—like that classic tomato sauce orange tint—add a squeeze of lemon. The citric acid provides a bit of a bleaching effect without the toxicity of actual bleach.
Silverware and Fine China: Be Careful
Now, here is where some "experts" get it wrong. You’ll see people online telling you to clean everything with baking soda. Don't do that.
If you have antique silver, be cautious. There’s a popular trick involving aluminum foil, hot water, and baking soda to remove tarnish. It’s an electrochemical reaction that transfers the sulfur from the silver to the foil. It works amazingly well, but it can also strip away the "patina" or the deliberate oxidation in the crevices of ornate patterns that gives silver its character. If you want your silver to look brand new and shiny like a mirror, go for it. If you want to keep that antique "depth," stick to a dedicated silver polish.
And gold-rimmed plates? Keep the soda away. The abrasive nature, however mild, can slowly thin out the gold leaf over time. Use it for the grit, not the glitz.

The Myth of the Vinegar Volcano
We need to address the "Volcano" in the room. You’ve seen the TikToks. People pour baking soda into a drain or a greasy pan, then dump vinegar on top. It fizzes. It looks like it’s doing a lot of work.
In reality? You’re mostly making salty water and CO2 gas.
The fizzing can help physically dislodge some loose debris, which is why it’s okay for a slow drain, but for actual grease removal on dishes, the two ingredients actually cancel each other out. Baking soda is a base. Vinegar is an acid. When you mix them, they move toward a neutral pH. You’re better off using them sequentially. Use the baking soda paste to scrub the grease, rinse it, and then use vinegar if you want to remove hard water spots or add shine. Using them together is just theater.
Practical Steps for Your Kitchen Routine
If you want to actually start using baking soda for cleaning dishes effectively, stop keeping it in that annoying cardboard box. It gets soggy. It clumps. It’s a mess.
- Transfer to a Shaker: Buy a stainless steel or plastic spice shaker. Fill it with baking soda and keep it right next to your dish soap. When you hit a greasy pan, just shake some on like you’re seasoning a steak.
- The "Pre-Soak" Bucket: If you’re hosting a big dinner, fill a basin with warm water and half a cup of soda. Toss the silverware in as people finish eating. It prevents the food from drying and hardening, making the actual cleanup 10x faster later that night.
- Coffee and Tea Stains: Mugs get those brown rings that soap can't touch. Sprinkle a little soda on a damp cloth and rub. The stains disappear in seconds. It’s much safer than using a scrubby pad that might scratch the glaze of your favorite mug.
- Cleaning the Sponge: Your sponge is a bacteria factory. While you should replace them often, you can extend the life of a smelly sponge by soaking it in a strong baking soda solution (4 tablespoons per quart of water). It kills the odors and helps break down the gunk trapped in the fibers.
Why This Matters for Your Health
Most commercial dish soaps and "heavy-duty" cleaners contain surfactants like SLS or fragrances that can irritate sensitive skin. If you have eczema or just find that your hands get incredibly dry after doing the dishes, switching to a more natural abrasive like baking soda can be a lifesaver. It’s non-toxic. If a little bit stays on the plate, it won't hurt you. You can’t say the same for some of the industrial-strength degreasers found under the sink.

Also, consider the environmental impact. Every time you rinse those blue and purple chemical gels down the drain, they end up in the water system. Sodium bicarbonate occurs naturally. It’s biodegradable. It doesn't disrupt aquatic life. It's one of the few instances where the "green" option is actually cheaper and more effective than the chemical one.
Troubleshooting Common Issues
Sometimes the soda leaves a white, chalky residue. This happens if you use too much or don't rinse thoroughly. If your dishes feel "gritty" after drying, just do a quick rinse with a 50/50 water and vinegar mix. The vinegar will dissolve any remaining bicarbonate particles and leave the surface squeaky clean.
Another thing: don't use it on aluminum. Baking soda can cause aluminum to oxidize and turn a dark, dull grey. It won't necessarily "break" the pan, but it will make it look terrible. Stick to stainless steel, cast iron (if you're careful and re-oil after), ceramic, and glass.
What to Do Next
Start small. Don't go throwing out all your dish soap today. Tomorrow morning, when you have that ring of dried coffee in your mug or a greasy frying pan from bacon, reach for the baking soda instead of the heavy-duty scrubber. Shake a light layer over the damp surface, let it sit for just three minutes, and then wipe it with a standard sponge. You’ll notice the grease "clumps" together and lifts off rather than just smearing around the pan.
Once you see how much easier it makes the "impossible" stains, move a permanent supply to your sink area. It’s the easiest upgrade you can make to your cleaning routine that pays for itself in about two days.
