There is something faintly ridiculous about the modern cleaning cupboard.
One bottle for the kitchen. Another for the bathroom. One for glass. One for mould. One for the floor. One for the dog. One with a lemon on the label, another with a waterfall, and another promising such extraordinary antibacterial devastation you half expect it to require a firearms licence.
Somewhere along the way, cleaning became complicated.
And rather profitable.
The basic sales pitch has been wonderfully effective: every new mess apparently requires a new chemical.
Grease? Buy this.
Shower grime? You’ll need that.
Dog accident? Entirely different bottle.
Kitchen bench? Under no circumstances use the bathroom one, apparently.
Before long, the cupboard under the sink looks less like a useful collection of household products and more like the storeroom of a small laboratory.
We’ve confused “strong smelling” with “clean”
For decades, cleaning brands have taught us that cleanliness has a smell.
Pine. Lemon. Lavender. Ocean breeze.
Quite why an ocean breeze should smell like a recently disinfected public toilet remains one of chemistry’s great mysteries.
But fragrance is largely theatre. A house doesn’t need to smell chemically clean to actually be clean.
And that distinction matters.
Many traditional cleaners are designed not only to clean, but to leave something behind: fragrance, surfactants, coatings or other ingredients that tell your nose a job has been done.
There is another way to think about cleaning.
Instead of asking, “What can we add?”
Ask:
“What do we actually need?”
Enter hydrogen peroxide
Hydrogen peroxide sounds intimidating.
This is mostly because anything ending in peroxide sounds as though it belongs either in a science laboratory or in the hair of a 1980s rock guitarist.
But its chemistry is surprisingly simple.
Hydrogen peroxide is H₂O₂.
Water is H₂O.
That extra oxygen molecule is what makes hydrogen peroxide useful. It is an oxidising agent, meaning it can react with and break down certain organic compounds and microorganisms.
After doing its job, hydrogen peroxide breaks down into water and oxygen.
Which is rather elegant when you think about it.
No tropical rainforest fragrance required.
No lingering perfume to convince you the bench is clean.
Just chemistry doing what chemistry does.
