Baking soda is more than just a baking ingredient—it’s a versatile, eco-friendly powder used in cooking, cleaning, personal care, and even health remedies. From deodorizing your fridge to soothing skin irritation, baking soda proves itself as a household essential with countless everyday applications.
Baking soda, or sodium bicarbonate (NaHCO₃), is a fine white powder with mildly alkaline properties. It dissolves easily in water and reacts gently with acids without causing harm. It’s non-toxic, non-irritating to the skin, and environmentally friendly—making it a staple in homes around the world.
Origins and History of Baking Soda
Baking soda traces its roots back to ancient Egypt, where a naturally occurring compound called natron—containing sodium bicarbonate—was used for cleaning and embalming. In the 18th century, European chemists began isolating and producing purified sodium bicarbonate for household and industrial use.
By the mid-19th century, the first commercial baking soda company in the U.S. emerged under the name Arm & Hammer, a brand still widely recognized today. From there, baking soda spread globally, becoming a trusted ingredient in cooking, cleaning, and health care.
Chemical Properties of Baking Soda
Sodium bicarbonate is odorless, white, and slightly salty. Its key trait is its mild alkalinity. When it reacts with acids—such as citric acid in lemon juice or acetic acid in vinegar—it releases carbon dioxide (CO₂), which is the same reaction that causes baked goods to rise.
Chemical reaction: NaHCO₃ + H⁺ → Na⁺ + CO₂↑ + H₂O
Baking soda also absorbs odors, neutralizes acids, and breaks down grease effectively. With a pH of around 8.3, it’s ideal for balancing acidity in both the body and household environments.
Baking Soda in Cooking
Baking soda is a beloved leavening agent among bakers worldwide. It helps create light, fluffy textures in baked goods by releasing CO₂ when combined with acidic ingredients.
Beyond baking, it serves multiple culinary purposes:
- Tenderizing meat: A light baking soda marinade softens meat and enhances juiciness.
- Cleaning produce: Soaking fruits and vegetables in baking soda water for 10–15 minutes helps remove pesticide residues.
- Balancing acidity: A pinch of baking soda can mellow overly sour soups or sauces.
- Deodorizing hands: Rubbing hands with baking soda paste removes lingering odors from garlic or onions.
Household Cleaning with Baking Soda
In an age of chemical-free living, baking soda has become a go-to cleaning agent. It’s safe, effective, and adaptable across various household zones:
Kitchen
- Cleans greasy stovetops, ovens, and range hoods.
- Forms a paste to scrub burnt pots and pans.
- Neutralizes odors in trash bins and refrigerators.
Bathroom
- Scrubs soap scum and limescale from tubs and tiles.
- Combines with vinegar to unclog and deodorize drains.
Other Areas
- Sprinkled on carpets or mattresses to absorb moisture and odors before vacuuming.

Moreover, baking soda and acetic acid (vinegar) are a popular duo for natural cleaning. Learn how to use acetic acid safely.
Health and Beauty Uses of Baking Soda
For decades, baking soda has been used in personal care thanks to its gentle antibacterial and acid-neutralizing properties.
Oral Care
- Brushing with baking soda paste helps reduce plaque and surface stains.

Baking Soda for the Environment and Pets
This isn’t just good for humans—it’s kind to the planet and safe for animals. It leaves no toxic residue and can replace harsher chemical products.
- Cleans gardening tools and hands after handling fertilizer.
- Sprinkled around plants to deter ants and certain pests.
- Used in litter boxes or pet cages to control odor safely.
Extra Tips for Using Baking Soda
Deodorize refrigerators: Leave an open box inside to absorb odors for months.
Laundry booster: Add half a cup to the wash for softer, fresher-smelling clothes.
