How to Make Homemade Baking Soda to Make Your Whole Home Shine | July 16, 2025

Do you have a dull sink, a dirty bathtub or a dull hob? No need to run to the supermarket or spend a fortune on household products with hard-to-decipher compositions. What if we told you that a simple mix of ingredients you already have in your cupboards can make all the difference? Better yet: we reveal the whole truth about the so-called “homemade baking soda”… and a very convincing alternative!
Homemade baking soda: myth or reality?
It’s a question that comes up a lot: can you make baking soda yourself, with salt, baking powder and a little vinegar? The answer, bluntly: no, it is impossible to produce real baking soda from these ingredients. But… There is a clever little diversion!

The baking powder used in baking already contains a small amount of baking soda, combined with a dry acid (often cream of tartar). When water is added or heated, a reaction occurs with the release of carbon dioxide in the form of bubbles. This is what makes cakes moist… or who can, as you will see, clean a faucet thoroughly!

Why is salt not used to make baking soda?

Salt, that good old sodium chloride, doesn’t really belong in this homemade recipe. It does not react chemically to produce bicarbonate. On the other hand, its slightly abrasive texture is perfect for scrubbing without scratching. In other words: he does not “create” anything, but he brings a very useful hand!
The really clever trick: create an effervescent cleansing foam
That’s where white vinegar comes in! Mixed with baking powder or baking soda, it triggers a natural effervescent reaction that loosens dirt, grease and even traces of limescale.
