Looking to green your cleaning routine? To help you get started, here’s everything you need to know about cleaning with bicarbonate of soda. From what you can and can’t 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 it’s actually a must-have green cleaning essential? It’s true. Bicarbonate of soda is a great non-toxic all-rounder for making almost every nook and cranny of your home sparkle.
Before you get started with your new eco-cleaning BFF, here’s everything you could ever need to know (and more!) about using it:
Everything You Need To Know About Cleaning With Bicarbonate Of Soda
Let’s roll up our sleeves, pop on our rubber gloves, and dig in!
What Is Bicarbonate Of Soda?
First off, you might be wondering what bicarbonate of soda actually is.
Bicarbonate of soda is a food-safe mineral salt, first discovered in 1801. In the early 1800s, it was commonly used by fishermen as a preservative to prevent freshly caught fish from going off.
Whilst fishermen got to keep bicarbonate of soda all to themselves for quite some time, eventually, some curious people started to explore other uses of this salt. In 1846, people started using it in baking, before – thankfully for us – being used as a cleaning product a few years later.
Is It The Same As Baking Powder?
It’s a common misunderstanding, but 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, it isn’t suitable to clean your home with. It has a very delicate composition, which means it’s simply not up to any cleaning jobs. Find out more in my full explainer on why you can’t use baking powder to clean with.
What About Baking Soda?
If you come across any green cleaning recipes online or in books, you might see baking soda listed as a key ingredient.
This can get confusing for anyone in the UK. However, whenever you see baking soda listed as an ingredient, don’t worry. It’s just plain old bicarbonate of soda that they are referring to. This is because bicarbonate of soda is the same thing as baking soda.
Baking soda – and sometimes sodium bicarbonate – are terms commonly used in America. In the UK and in places like Australia and New Zealand, the terms bicarbonate of soda or bicarb are used.
Why It’s So Good For Cleaning
What makes bicarbonate of soda so good for cleaning all comes down to chemistry.
Don’t worry, I’ll save you from a full-on chemistry lesson here. All you need to know is that bicarbonate of soda is chemically a base.
Bases react with oils and fats and dissolve them. This means that bicarbonate of soda will tackle dirt, grease, oil, and fats around the home with ease.
What’s more, bicarbonate of soda can tackle bad smells by neutralising or reducing bad odours around your home. Your fridge, carpet, rug, shoes, and everywhere in between can all benefit from bicarbonate of soda’s amazing deodorising properties.
Is it wizardry? No, it’s chemistry again! How it works is that the bicarbonate of soda reacts with the acidic molecules responsible for bad odours and neutralises them. It’s known as an acid-base reaction, in which neutralisation is almost always the outcome.
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.
All in all, it’s pretty impressive work from just one cardboard box!
Things You Can Clean With Bicarbonate Of Soda
Bicarbonate of soda is a natural cleaning superhero. As such, it can be used in a variety of applications around your home. Here are just a few of my favourite uses:
In The Kitchen
- 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 give it a fragrance boost, try adding a few drops of your favourite essential oil.
- 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.
- To clean a ceramic sink, sprinkle a little bicarbonate of soda into the sink. Take a damp cloth or sponge and gently scrub the sink to remove any dirt and stains. Test in an inconspicuous area of the sink first to make sure it won’t cause any damage.
In The Laundry
- Add a scoop to your laundry (around one tablespoon) to help keep whites white. For best results, pop it in the laundry detergent drawer alongside your laundry powder, or add it directly to your drum.
Around The House
- 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 a few hours, then vacuum up the powder. See my full guide to removing bad smells from shoes using bicarbonate of soda for more details.
Things You Should Never Clean With Bicarb
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:
Glass
Whilst bicarbonate of soda is a mild abrasive, it can still scratch or damage glass or mirrors. For a non-toxic alternative for this job, try cornflour. This is an even milder abrasive, better suited for cleaning glass.
Aluminium
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 oxidation.
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.
Wood
Similar to stone, bicarbonate of soda can damage the finish or sealant on wood furniture. Repeated use could eventually cause a dull finish on your furniture, so it is best avoided.
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 of gold plating. Eventually, it will cause the plating to wear off, so it should be avoided at all costs.
Can You Use Bicarbonate of Soda & Vinegar To Clean?
There is a lot of confusion around using bicarbonate of soda and vinegar. However, the truth is that 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. So whilst it’s not harmful to mix the two, there are many more effective ways to clean your home!
You see so many articles or suggestions online to mix the two when cleaning, so I can see why people are misinformed. I think this misinformation shows that even with natural cleaning, we still need to understand 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 to make green cleaning easy and effective for everyone! If you want to know more, here is a full article on why you shouldn’t mix vinegar and bicarbonate of soda.
What About Combining Bicarbonate Of Soda & Lemon?
Given that lemon is a great natural cleaner, you may also be wondering if you can combine bicarbonate of soda and lemon to make a cleaning solution.
Again, given that lemon is acidic and bicarbonate of soda is a base, they will cancel each other out. So make sure you always keep the two apart!
Is Bicarbonate Of Soda Eco-Friendly?
It’s always good to question the provenance of the items we use to clean our homes. So, if you are wondering if bicarbonate of soda is eco-friendly, then that’s a very good question.
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 that we have thousands of years before the world’s supply of trona dries up.
Destructive opencast mining doesn’t tend to be used to extract bicarbonate of soda’s 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 Solvay 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 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 judgement on this.
Where To Buy Bicarbonate Of Soda
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 take a look at my guide on where to buy bicarbonate of soda for cleaning.

I recently saw on “Steph’s Packed Lunch” a suggestion that Bicarbonate of Soda can be used to clean external block paving (mixed with a little water and possibly some cooking salt). Do you believe this would work? and roughly how much Bicarb to Water?
Many Thanks
Malcolm Rogers
Hi Malcolm, I haven’t tried that myself but it sounds like that would work as the salt and bicarb would act as a mild abrasive to remove any dirt. To save your back, you’d need to scrub it with a long-handled hard bristled garden brush. How I would make it would probably to add just enough water to make a paste, and then apply the paste to the slabs before wetting the brush and then scrubbing, and then rinsing clean with a watering can or hose. Do let me know how you get on – I’m very intrigued!
Does mixing lemon juice with bicarb have the same neutralizing effect, and is therfore useless as a cleaner? I come across many posts regarding its use as a cleaner and for health benefits.
Hi Joe, yes, lemon juice is acidic so mixing it with bicarb has the same effect. Lemon juice can be used with vinegar though to make an effective cleaner – when you mix an acid and an acid there generally isn’t a reaction. I’ve got lots of info here in my post on using lemon and vinegar to clean
