Are you looking to green your cleaning routine? To help you get started, here’s everything you need to know about cleaning with bicarbonate of soda – one of the most common natural cleaning product ingredients. From what you can clean with it, how to use it, how to store it, and much more.

Whilst you might associate bicarbonate of soda with baking, did you know that bicarbonate of soda is a must-have green cleaning essential? It’s true. Bicarbonate of soda is a great non-toxic all-rounder at cleaning nearly every nook and cranny of your home.

Here is almost everything you could ever need to know about cleaning with this non-toxic and all-natural multi-tasker:

What Is Bicarbonate of Soda?

First off, you might be wondering what bicarbonate of soda actually is. Bicarbonate of soda is a mineral salt, first discovered in 1801. A food-safe ingredient, in the early 1800s, it was commonly used by fishermen as a preservative, to prevent freshly caught fish from going off. Whilst, in 1846 its usage became widespread in baking, before becoming well known as a cleaning product.

Outside of the UK, bicarbonate of soda is known as baking soda or sodium bicarbonate. So if you are confused by reading green cleaning recipes from other countries, then don’t worry. It’s just plain old bicarbonate of soda that they are referring to.

Is It The Same As Baking Powder?

Bicarbonate of soda is not the same as baking powder. Bicarbonate of soda is a single ingredient salt. Whilst baking powder does contain some bicarbonate of soda, it also contains cream of tartar, plus cornflour or rice flour. As baking powder is specifically mixed to aid with baking then it isn’t suitable to clean your home with.

Why Is Bicarbonate of Soda Good For Cleaning?

Bicarbonate of soda is chemically a base. Bases react with oils and fats and dissolve them. This means that bicarbonate of soda will tickle dirt, grease, oil, and fats around the home with ease.

As bicarbonate of soda is also a salt, it has mild abrasive properties. This means it provides a gentle scrubbing action, without leaving any scratches behind.

What’s more, bicarbonate of soda can tackle bad smells by neutralising or reducing bad odours around your home. From your fridge to your carpet or rug, to your shoes, and everywhere in-between. This is because the bicarbonate of soda reacts with the acidic molecules responsible for bad odours, and neutralises them.

All in all, it’s pretty impressive work from just one cardboard box!

What Can You Clean?

Bicarbonate of soda is a natural cleaning superhero. As such, it can be used in a variety of applications around your home:

Add a scoop to your laundry to help keep whites white.

To help deodorise stinky fridges, wardrobes or drawers simply add some bicarbonate of soda to a bowl. Place the bowl in the offending area, to help neutralise bad odours. For best effects, mix it every week, and replace the bicarbonate of soda every 3 months.

To deodorise stinky shoes, carpets or rugs, simply sprinkle some bicarbonate of soda directly into the inside of your shoes, or onto your carpet or rug. Leave it to sit for around an hour, then vacuum up the powder.

To deodorise food storage containers that have taken on a pungent smell, simply wipe them with a clean damp sponge sprinkled with bicarbonate of soda.

Likewise, to clean greasy, dirty, or oily surfaces in your kitchen, again, take a wet cloth and sprinkle some bicarbonate of soda on it. You can then wipe down your worktop, sink, microwave, cooker hood, and even your utensils.

These are just some of the applications for bicarbonate of soda. For more uses, see my book on making your own natural cleaning products – Fresh Clean Home.

Is There Anything You Shouldn’t Clean?

Whilst bicarbonate of soda can be used to clean many items and surfaces around your home, there are a few places where you should use alternative products:


Whilst bicarbonate of soda is a mild abrasive, it can still scratch or damage glass or mirrors. Cornflour is an even milder abrasive, better suited for cleaning glass.


Using bicarbonate of soda to clean aluminium surfaces, such as aluminium pans, can cause the aluminium to oxidise. This means the surface may eventually turn brown, after repeated cleaning. If you do accidentally use bicarbonate of soda on aluminium surfaces, rinse it off straight after cleaning to help avoid oxidisation.

Quartz, Marble, Granite or Other Natural Stone

Avoid using bicarbonate of soda on any natural stone surfaces, including quartz, marble, and granite. Over time, repeated bicarbonate of soda use can cause damage to the sealant, and eventually leave scratches on the stone.


Similar to stone, bicarbonate of soda can damage the finish or sealant on wood furniture. Repeated use will eventually cause a dull finish on your furniture.

Antique Silver

Cleaning your best antique silver with bicarbonate of soda isn’t recommended. This is because bicarbonate of soda can be too abrasive. As such, with repeated use, your silverware can eventually lose its patina and tarnish.

Gold Plated Utensils or Dishes

As gold is a very soft metal, bicarbonate of soda is too abrasive to clean these items. Prolonged use will scratch and ruin the finish on gold plating. Eventually, it will cause the plating to wear off.

Can You Use Bicarbonate of Soda and Vinegar To Clean?

You should never mix bicarbonate of soda with vinegar to make a cleaning solution. This is because when you mix the two, they react to form water, carbon dioxide, and salt. In other words, you are cleaning with nothing more than weak salty water. There are many more effective ways to clean your home!

If you want to know more, here is a full article on why you shouldn’t mix vinegar and bicarbonate of soda.

There is a lot of confusion around bicarbonate of soda and vinegar. You do see so many articles or suggestions online to mix the two when cleaning. It just shows, that even with natural cleaning, we still need to understand just a little about the science behind the products we use in our homes, and why we use them. I’m making it my aim to clear up any misunderstandings and make green cleaning easy for everyone!

Is Bicarbonate of Soda Eco-Friendly?

Bicarbonate of soda is made from soda ash. To produce soda ash, the naturally occurring minerals nahcolite and trona are mined from the ground, and these are then refined into soda ash. As well as bicarbonate of soda, soda ash is also used to make other products that we depend upon. This includes products such as food, pharmaceuticals, soap, detergents, glass, paper, and more.

Having to mine the raw materials does sound problematic. However, whilst trona and nahcolite are non-renewable resources, they are not fossil fuels. This means their usage does not emit greenhouse gases.

Most of the bicarbonate of soda that we find in the UK is mined in Turkey or Wyoming. Here vast reserves of naturally deposited trona are found.  It’s also estimated we have thousands of years before the world’s supply of trona dries up.

Opencast mining doesn’t tend to be used to extract the raw materials. Instead, water is injected into the ground. This then returns the saturated water to the surface, and the raw materials can be extracted by evaporating the water.

Can’t It Be Made Synthetically?

Soda Ash can be made synthetically, through a method called the Solvay Process. You would think that making it synthetically would be more environmentally friendly than mining soda ash. However, in actual fact, it is a more costly and energy and water-intensive production process than mining. The process also requires limestone mined from quarries, so it does not eliminate the need for mining. It seems far better to extract trona directly from the source.

All products have an impact. However, given that soda ash is used ubiquitously in many products that we depend on then it will be extracted from the ground anyway. Bicarbonate of soda is also so effective at cleaning our homes. As one box can replace a myriad of toxic cleaning products, I personally consider it eco-friendlier than any conventional cleaning product. Of course, do make your own judgment on this.

Where Can You Buy It?

Bicarbonate of soda can be bought in the baking aisle in any supermarket. However, it’s far cheaper to give the plastic tubs in the supermarket a miss and head to your nearest hardware store. Here you should be able to pick up a cardboard box of bicarbonate of soda for cleaning with and still have change from £2.

Needing to buy bicarbonate of soda in larger quantities? Or don’t have a hardware shop near you? Then do look at my guide on where to buy bicarbonate of soda for cleaning.
