Short answer: A split microfibre picks up dirt better because a suction-like, capillary effect arises between the split threads. Water and dirt are pulled deep into the core of the cloth instead of being pushed ahead. That is why water alone is enough, and the cloth also releases the dirt easily again when you rinse it out.
When cleaning, we often think of putting in force or of the product we use. The difference is somewhere else though: in the build-up of the thread itself.
Why do ordinary cloths leave dirt behind?
Cotton cloths and standard microfibers from the supermarket often just move the dirt around. They push bacteria and grease residue ahead of them instead of absorbing them. That is exactly where the familiar streaks on glass and the dull haze on high gloss furniture come from.

Absorbing instead of pushing ahead
A cloth is not a rag but an instrument: it determines how water and surface react to each other. Take a look at the iZi-Clean Wonder Cloth in the 12-piece pack.
What makes the splitting of the fibre so special?
The fibres of the iZi-Clean Wonder Cloth are split, which gives a very high density per square centimetre. That delivers three things:
- Capillary effect: the combination of polyester and polyamide creates a suction-like force. Water and dirt are pulled deep into the core of the cloth.
- No chemical necessity: the fine fibres penetrate into the microscopic pores of a surface. Water alone is enough for a hygienic result.
- Self-cleaning capacity: despite the absorption capacity, the cloth releases the dirt easily again when you rinse it out, so bacteria do not settle in it.
So why do you no longer need a cleaning product?
Because the dirt is removed physically instead of being dissolved chemically. That saves you a cupboard full of bottles and it saves residue on your surfaces. You can read how that works in practice on the page about streak-free cleaning.

Water is enough
Fewer products in the house means lower costs, fewer smells and less residue on your furniture. You will find all the variants in the Wonder Cloths collection.
What does that mean for the lifespan of your cloth?
Cloths that keep their structure keep giving the same result for years. Because you do not need any chemicals with them, that is immediately a lighter load on your interior and on the environment.
Where do you see the difference fastest?
On windows, mirrors and stainless steel. Those are the surfaces where every wipe shows up straight away. For mirrors, the method is set out on the page about cleaning mirrors streak-free.
