Why Bicarb and Vinegar Aren’t for Everything
🌱 DIY Green Cleaning Basics
By Analisa from Under Your Sink
One of the most common things I hear when people start talking about green cleaning is:
“I already use bicarb and vinegar for everything.”
This is the point where I quietly cringe - not because bicarb and vinegar aren’t useful (they are), but because they’re often being asked to do jobs they were never meant to do, and used in a way that takes away what little effectiveness they have.
Bicarbonate of soda (bicarb) and vinegar are two very handy ingredients.
They’re just not a complete cleaning system and they don’t work better when mixed together.
Understanding what each one actually does (and doesn’t do) is one of the simplest ways to clean more effectively without filling your cupboard with bottles.
Why bicarb and vinegar get treated like a cure-all
Bicarb and vinegar are easy to find, inexpensive, and familiar. Because they work well for certain jobs, it’s easy to assume they can be stretched to cover everything - dishes, laundry, bathrooms, floors, and more.
In practice, most people are using them for a handful of obvious jobs and mixing them together because it “looks like it’s working”.
Using fewer ingredients doesn’t mean forcing the same two to do every job. It means understanding what each ingredient is actually good at.
Bicarb: useful for odours and gentle scrubbing
Bicarb is best known for dealing with odours and providing gentle abrasion.
It’s commonly used around the home for things like:
- deodorising shoes
- freshening bin
- absorbing fridge smells
- light scrubbing where you don’t want to scratch
Used this way, bicarb is simple, forgiving, and effective.
Where people often run into trouble is expecting it to:
- replace dishwashing products
- handle laundry on its own
- clean floors properly
- deal with heavy grease
Those jobs usually need something that works differently.
Vinegar: useful for descaling and glass
Vinegar is most useful where mineral build-up and residue are the problem.
It’s commonly used for:
- cleaning windows and glass
- dealing with water marks
- descaling taps and kettles
- removing soap residue
This is where vinegar shines.
Where it tends to fall short is when it’s expected to:
- cut grease by itself
- clean heavily soiled surfaces
- replace a proper cleaner in laundry or dishwashing
Again, it’s a helpful ingredient - just not a solution for everything.
Why mixing bicarb and vinegar doesn’t help
When bicarb and vinegar are mixed, they react with each other. The fizz looks impressive, which is why this combination has become so popular.
The problem is that once the fizz settles, there’s very little cleaning ability left.
That’s why mixing bicarb and vinegar often feels satisfying but doesn’t deliver the results people expect. Each ingredient works better when it’s used on its own, for the job it’s suited to.
Why this matters
Once you understand what bicarb and vinegar actually do, you start to notice something.
A lot of cleaning products are doing the same basic jobs - dealing with odours, residue, grease, or build-up - just packaged as different solutions.
That shift in thinking is what changed everything under my own sinks.
Instead of relying on lots of products, I focused on understanding a small number of ingredients and using them well. And that’s when cleaning started to make a lot more sense.
Bicarb and vinegar are part of that picture - just not the whole picture.
Take it at your own pace
Green cleaning isn’t about replacing everything overnight. It’s about building understanding and using ingredients where they actually make sense.
If you’re already using bicarb and vinegar, you’re not doing it “wrong” - there’s just more value to be gained by knowing their limits as well as their strengths.
And if you’re ever unsure what to use for a specific cleaning job, I’m always happy to help.
This is about confidence, not perfection.
