Washing Soda vs Baking Soda: What's The Difference?

Washing Soda vs Baking Soda: What's The Difference?

Although washing soda and baking soda might sound interchangeable, these two substances have distinct chemical compositions, uses, and effects. From the science behind their structures to their everyday applications in our homes, this guide explores everything you need to know about washing soda vs baking soda. 

Definition of Washing Soda and Baking Soda

Washing soda, scientifically known as sodium carbonate (Na2CO3), is a whiteish powder with larger granules. It's a strong alkaline compound known for its cleaning properties and isn’t suitable for consumption. 

Baking soda, or sodium bicarbonate (NaHCO3), is a fine white powder used in baking and cleaning. It's a weak base that can be used in food preparation and personal care products.

Importance in Household and Industrial Use

Both washing soda and baking soda are essential in various household and industrial applications. 

Washing soda is typically used in glass manufacturing, water treatment, and as a laundry booster

Baking soda is generally used in food preparation, pharmaceuticals, and as a mild cleaning agent. 

Washing Soda vs Baking Soda: Chemical Composition and Physical Differences

The chemical composition and physical appearance of washing soda and baking soda play a vital role in their functionality. This section delves into their chemical makeup, pH levels, and differences in appearance and texture.

Washing Soda (Sodium Carbonate)

Washing soda is a salt of carbonic acid, characterized by a pH of around 11.6. It's used mainly as a laundry booster, and its coarse texture makes it a more abrasive cleaner. It's produced by mining trona and then processing it into a usable form.

Baking Soda (Sodium Bicarbonate)

Baking soda is a salt composed of a sodium cation and a bicarbonate anion, with a pH of around 8. It's widely known as a leavening agent in baking, and its fine, dusty granules dissolve easily in water, making it a mildly abrasive cleaner.

Key Differences in Composition

The main difference between washing soda and baking soda lies in their chemical composition and pH levels. Washing soda is more alkaline and abrasive, while baking soda is milder and more versatile. Washing soda's higher pH makes it suitable for heavy-duty cleaning, while baking soda's neutral pH allows for a wide range of applications.

Physical Appearance and Texture

Washing soda has larger, visible granules and a higher density, while baking soda is a fine powder. This difference in texture affects how they dissolve in water and their cleaning effectiveness. 

Washing soda's coarser texture makes it suitable for scrubbing, while baking soda's fineness allows for gentle cleaning.

Washing Soda vs Baking Soda: Common Uses

Washing soda and baking soda are widely used for various purposes, from cleaning to personal care. 

Washing Soda Uses

  • Cleaning: Washing soda is effective in removing grease and stains from ovens, grills, and sinks. It can be mixed with water to create a paste for scrubbing.
  • Laundry: It enhances detergent's effectiveness, balances the pH level of water, and softens fabrics.
  • Water Softening: Washing soda acts as a water softener, making it useful in laundry applications, especially in areas with hard water.

Baking Soda Uses

  • Baking: Baking soda is a common leavening agent in baked goods, reacting with acidic ingredients to release carbon dioxide.
  • Cleaning: It's used for scrubbing and cleaning various surfaces, including kitchen counters and bathroom ceilings.
  • Personal Care: Baking soda is found in toothpaste for whitening teeth and can be taken as an antacid to neutralize stomach acid.

Washing Soda vs Baking Soda: Effectiveness and Efficiency

The effectiveness and efficiency of washing soda and baking soda are determined by various factors such as pH levels and abrasiveness. 

Cleaning Performance Comparison

Washing soda is more abrasive and cleans well but can scratch delicate surfaces. Baking soda is milder and takes longer to clean but does not usually damage surfaces. The choice between the two depends on the surface material and the type of dirt or stain.

Environmental Impact

Both washing soda and baking soda are considered environmentally friendly. They’re natural substances that don't harm the environment, unlike many commercial cleaners that contain harsh chemicals.


Washing soda and baking soda are affordable and offer a cost-effective solution for various cleaning needs. They can replace multiple commercial products, reducing both costs and environmental impact.

Washing Soda vs Baking Soda: Safety and Precautions

Safety is paramount when using washing soda and baking soda, but they have different handling and safety guidelines. Let’s take a closer look. 

Handling Washing Soda

Washing soda isn’t edible and can damage the eyes and skin. Gloves should always be worn when cleaning with it, and it should be kept out of reach of children and pets.

Handling Baking Soda

Baking soda is edible but shouldn’t be inhaled. It's mild enough to be used without gloves but can irritate the eyes. Care should be taken when using it in large quantities or for extended periods.

Storage Recommendations

Both substances should be stored in airtight containers to maintain their effectiveness. Washing soda, in particular, can soak up moisture if not stored properly, leading to clumping and reduced effectiveness.

FAQ About Washing Soda vs Baking Soda

Can I Substitute Washing Soda for Baking Soda?

No, washing soda shouldn’t be substituted for baking soda in recipes or personal care products due to its caustic nature and higher pH. It can cause harm if ingested or applied to the skin.

Where Can I Buy Washing Soda and Baking Soda?

Both can be purchased at grocery stores or online. Washing soda is typically found in the laundry section, while baking soda is found in the baking aisle. Specialty stores may also carry them in bulk.

Can You Use Washing Soda in HE Washing Machines?

Yes, washing soda is suitable for HE washing machines. It should be used in smaller quantities due to the lower water usage in these machines. Following the manufacturer's guidelines ensures proper usage.
