Bicarbonate of soda is one of the simplest, most affordable ways to clean your home naturally — and chances are you already have some in the cupboard.
It’s gentle, versatile and surprisingly effective for everyday cleaning jobs around the home without needing lots of separate products.
If you’re trying to create a lower tox home without overwhelm, bicarbonate of soda is one of the best places to start.
In this guide, we’ll cover:
- what bicarbonate of soda actually does
- simple DIY cleaning recipes
- where it works best
- what not to mix it with
- easy ways to use it in a realistic busy home
What Is Bicarbonate of Soda?
Bicarbonate of soda (also called baking soda) is a naturally occurring alkaline powder.
For cleaning, it works because it:
- helps lift grease and grime
- gently scrubs surfaces without scratching
- absorbs odours
- helps break down build-up
It’s especially useful for:
- sinks
- ovens
- pans
- mattresses
- bins
- fridges
- grout
- laundry
- deodorising carpets and upholstery
And unlike many conventional cleaners, it doesn’t leave behind strong chemical smells.
1. Everyday Sink Cleaning Paste
One of the easiest ways to use bicarbonate of soda is as a simple cleaning paste.
You’ll need:
- 3 tablespoons bicarbonate of soda
- small splash of water
Mix into a thick paste.
Use on:
- stainless steel sinks
- ceramic sinks
- taps
- baths
- shower trays
Apply with a cloth or sponge, gently scrub, then rinse away.
For tougher marks, leave for 5–10 minutes before wiping clean.
2. Burnt Pan Cleaner
This is one of the most popular low tox cleaning swaps because it genuinely works well.
Method:
Sprinkle bicarbonate of soda generously over the bottom of the pan.
Add:
- a small amount of warm water
- or a splash of washing up liquid for extra grease cutting
Leave for 15–30 minutes, then scrub gently.
For stubborn burnt-on residue:
- add hot water
- simmer briefly
- allow to cool
- then scrub again
3. Mattress & Carpet Freshener
Bicarbonate of soda is brilliant for absorbing smells naturally.
How to use:
Sprinkle lightly over:
- mattresses
- carpets
- rugs
- sofas
Leave for at least 30 minutes (longer if possible), then vacuum thoroughly.
Helpful for:
- pet smells
- musty rooms
- children’s mattresses
- general freshening between deep cleans
You can also add a few drops of essential oil to the powder beforehand if you enjoy a subtle natural scent.
4. Fridge & Bin Deodoriser
Place a small open jar of bicarbonate of soda:
- in the fridge
- at the bottom of bins
- near shoes
- in utility cupboards
It helps absorb odours naturally rather than masking them.
Replace every few weeks.
5. Simple Oven Cleaning Paste
A bicarbonate paste works well for everyday oven maintenance.
Mix:
½ cup bicarbonate of soda
enough water to form a spreadable paste
Spread onto greasy areas and leave overnight if needed.
Wipe away with warm water and a cloth.
For heavier grease, you may need:
- repeat applications
- a scraper
- or an oxygen bleach based cleaner for tougher jobs
6. Laundry Boosting
Bicarbonate of soda can help:
- soften odours
- freshen laundry
- support detergent performance
Try adding:
1–2 tablespoons into the drum with laundry
Especially useful for:
- gym wear
- pet bedding
- towels
- musty fabrics
What Not to Mix With Bicarbonate of Soda
A common misconception is that mixing bicarbonate of soda with vinegar creates a stronger cleaner.
In reality, they mostly neutralise each other.
The fizz can help loosen dirt temporarily, but after the reaction you’re largely left with salt water.
That’s why bicarbonate of soda usually works best:
- on its own
- with water
- or alongside a small amount of washing up liquid
For acidic cleaning jobs like limescale, Citric acid is often more effective.
Is Bicarbonate of Soda Safe for All Surfaces?
It’s gentle compared to many abrasive cleaners, but always use caution on:
- delicate stone
- polished surfaces
- aluminium
- specialist coatings
Test first if unsure.
A Simple Place to Start
If you’re feeling overwhelmed by “perfect” eco cleaning advice, start here:
You do not need:
- dozens of products
- complicated routines
- or a fully plastic-free home overnight
Often the simplest swaps are the ones that stick.
Bicarbonate of soda is affordable, versatile and genuinely useful for everyday family life — especially when paired with a few gentle essentials that make cleaning easier.
