Baking soda vs baking powder: Which cleans better?

When it comes to household cleaning, the ongoing discussion of baking soda vs baking powder for cleaning is a classic dilemma. These kitchen staples are not only known as baking essentials but also as cleaning agents with distinct capabilities.

But is baking soda the same as baking powder? Despite their similar names and appearance, the answer is actually no. This similarity often leads to confusion, especially when it comes to choosing them for cleaning purposes.

This guide aims to clarify the distinction and compare baking powder vs baking soda for cleaning. Whether fighting stubborn kitchen grime or aiming for a pristine bathroom, choosing the appropriate substance can significantly impact your cleaning results.

What is baking soda?

Baking soda, scientifically known as sodium bicarbonate, is a versatile compound renowned for its leavening abilities in baking and its potency as a cleaning agent. Its natural alkaline properties make it excellent for neutralising acids and breaking down proteins, which is why it’s so effective in removing stubborn stains and odours.

Baking soda requires an acidic component to activate its leavening effects for baking purposes. However, it stands alone as a powerful cleaning tool without the need for additional acidic agents.

What is baking powder?

Baking powder is a complete leavening agent that combines baking soda with one or more acid salts, such as cream of tartar, and often a moisture absorber like cornstarch. It contains both the alkali and acid necessary for leavening, allowing it to produce carbon dioxide gas when moistened and then heated and causing dough or batter to rise on its own. 

In cleaning, though, baking powder’s built-in acidic properties limit its effectiveness. But, even if it’s not as potent in heavy-duty cleaning tasks, you can still use it for light cleaning applications. Especially in instances where minor abrasiveness and slight acidity are beneficial.

Baking powder vs baking soda for cleaning: Which is better?

Both baking powder and baking soda have their own unique strengths when it comes to cleaning. Baking soda’s alkaline nature makes it a powerful degreaser and deodoriser while baking powder’s built-in acids make it useful for light scrubbing and freshening tasks.

Ultimately, the difference between baking soda and baking powder for cleaning depends on the specific task at hand and a lot of other factors. Here’s a rundown of how each performs when house cleaning and more.

In terms of pH level

It’s common knowledge to use baking soda or bicarbonate of soda for cleaning. With its high pH level of around 9, it exhibits strong alkaline properties. This makes the alkaline baking soda effective in breaking down organic compounds and grease. It also makes it easier to clean tough stains and odours.

On the other hand, baking powder has a lower pH than baking soda due to its acidic components. Its pH level can vary depending on the specific acids used in its formulation, but generally, it hovers slightly above neutral.

This reduced alkalinity makes baking powder less aggressive than baking soda. This is why it’s usable in gentler cleaning tasks where a balanced pH is beneficial to avoid damage to sensitive surfaces.

In terms of reactivity

Baking powder is a mixture of baking soda and an acid, which is usually cream of tartar. This acid ingredient reacts with the baking soda to produce carbon dioxide bubbles when activated by moisture and heat. This, in turn, creates air pockets in baked goods and makes them 'rise'.

But can you use baking powder to clean? Well, yes, the same reaction can be utilised for cleaning purposes as well. The bubbling action helps loosen tough stains or grime on surfaces and acts as a mild abrasive when mixed with some water.

However, baking soda by itself is highly reactive. It serves as an all-purpose cleaning agent without the need for any acid component and often be used in many ways when cleaning a house. 

In terms of odour control

Another distinction between baking soda and baking powder is their ability to control odours. Baking soda has long been used as a natural deodoriser because it can absorb and neutralise unpleasant smells.

Meanwhile, baking powder doesn’t have this capability as it lacks a strong alkaline component. Its main function is to make baked goods rise, and it does not have any significant impact on odours. 

In terms of safety

Another critical difference between baking soda and baking powder is their safety. 

Baking soda is a straightforward and harmless ingredient that has been used in cooking and cleaning for decades. This is not to say that you can’t add too much baking soda. If taken in large quantities, it can cause stomach upset and electrolyte imbalances. However, when used in appropriate amounts for deodorising purposes, baking soda is entirely safe to use.

On the other hand, some types of baking powder may contain aluminium compounds, which can be harmful when ingested in large quantities. It’s essential to check the label and ensure the baking powder you’re using is aluminium-free. 

In terms of cleaning application

While both baking soda and baking powder have cleaning capabilities, they vary in their application methods. Here are the differences between cleaning with baking powder vs baking soda.

Baking soda can be used on its own as a scrub or mixed with water to create a paste that is suitable for multiple surfaces and stains. It’s also gentle enough to use on delicate items without damaging them.

It’s different when you use baking powder as a cleaner since it needs to be combined with other substances, such as water, first. 

But does baking powder remove stains? The short answer is yes, but it requires mixing baking powder with water. It’s also not recommended for use on delicate surfaces as it can be abrasive.

For instance, if you’re cleaning light fixtures, it would be a better option to sprinkle baking soda as it won’t scratch the delicate surface. But for tougher stains on kitchen countertops, a mixture of baking powder and vinegar may be more effective. 

In terms of availability and cost

Another factor to consider when deciding between baking soda and baking powder is their availability and cost.

Baking soda is widely available in most grocery stores and can be purchased at a low cost. On average, a 100-g pack will be sold from $1 to $2.45, and a 1-kg bag will range from $4 to $8. It’s also a versatile ingredient that can be used for various purposes, which makes it a cost-effective option.

In comparison, baking powder may be more challenging to find in certain areas and typically costs more than baking soda. 100-g packs can cost anywhere from $2 to $5, and 1-kg bags can sell for $8 to $20.
