The simplest and often the most necessary method: we treat exactly the surfaces people touch.
Surface disinfection is a two-stage process, and both stages are compulsory. Skip one and the other does not work — that is not a formality, it is how the method works.
Step one — mechanical cleaning. We remove dirt, grease and dust so the product can physically make contact with the surface itself.
Step two — treatment with contact time. We apply the product and leave it on the surface for as long as it needs, and only then wipe it off if required.
Unlike fogging and ozone, this method is selective: we treat exactly the surfaces that matter rather than the whole room uniformly. In practice most of the attention goes to contact surfaces — the places people touch most often.
This is the most commonly skipped part and the main reason "disinfection" sometimes produces no result. The mechanism is simple and physical.
That is exactly why in professional practice cleaning and disinfection are two steps, not alternatives. Cleaning removes dirt; disinfection reduces the number of micro-organisms on an already clean surface. Combined "clean and disinfect" products in a single bottle only work if the surface is already reasonably clean.
The second most common reason a treatment does not work: the product is wiped off too soon. Disinfection is not an instant reaction — the active substance needs time to break down the cell structures of micro-organisms. This time is stated for each product and varies considerably between products.
If the surface is wiped straight after application, all that has happened is the mechanical removal of dirt with a damp cloth. The active substance has been bought, applied and wiped away without having time to do what it was paid for.
A product sprayed on and wiped straight off is a product thrown away.
Materials have to be taken into account here. Untreated timber, natural stone, some varnished and oiled finishes and soft plastics react differently to different products, so before treatment we establish what we are dealing with and, where necessary, choose a different product or a different method.
There is an honest limit too: surface treatment does not reach anything that is not a surface. It does not work in textiles, soft furniture filling, gaps or ventilation ducts — those need ozone treatment or cold fogging.
The value of the method depends on whether the right surfaces are treated. In practice attention usually goes to large, visible planes — tables and floors — even though those are exactly what people touch least.
One more thing almost everybody misses: separating the zones. If the same cloth goes from the toilet to the kitchen, the treatment not only fails to work but actively transfers contamination. In practice this is handled with separate cloths and a set order of work — from the cleanest zone to the dirtiest, never the other way round.
| Mistake | Why it is a problem |
|---|---|
| Disinfecting a dirty surface | The product never reaches what is under the layer of dirt |
| Wiping the product off straight away | The contact time is not observed — the treatment does not work |
| Using one cloth for every room | Transfers contamination from one surface to another |
| Treating only the visible surfaces | Switches, handles and handrails are often missed |
| Spraying onto the cloth, not the surface | The amount of product on the surface becomes unpredictable |
| Mixing different products | Can reduce effectiveness or produce harmful gases |
One more mistake that does not fit in the table but matters: how often the treatment happens. Surface disinfection acts on what is on the surface at the moment of treatment. As soon as it is touched, it is a contact surface again. So in places with heavy footfall a one-off treatment achieves little — what works there is a regular schedule.
For flats, from €55 depending on the number of rooms. For commercial premises, €0.70 to €1.20/m². For regular treatment on a schedule we prepare a separate quote — see Regular disinfection.
Cleaning removes dirt. Disinfection reduces the number of micro-organisms on a surface. Disinfection without cleaning first does not work, so in practice they are two steps rather than alternatives.
The treatment acts on what is on the surface at the moment of treatment. As soon as the surface is touched it becomes a contact surface again — which is why regular scheduled treatment makes sense in places with heavy footfall.
Yes, surface treatment allows that, unlike fogging and ozone treatment. In practice we often do it before or after working hours, so as not to disturb anyone and to give the product time to work.
