Micro steam is hot, very fine water vapour with a low water content. It dissolves grease, limescale and dirt with heat alone, without any cleaning agent. This page explains how it works, what it can do and what is really proven. Without advertising promises.
Micro steam is hot, very fine water vapour at around 180 °C. It dissolves grease, limescale and dirt with heat alone, without any cleaning agent, and reduces germs through heat (proven: CDC, Sexton 2011).
The technology in numbers
Inside the device, ordinary tap water is heated strongly under pressure. This creates a particularly hot, fine steam with a low water content. The drier the steam, the less residual moisture remains on the surface, and the faster it dries. Professional devices like Thermostar and MediCleanTec reach around 180 °C; according to the manufacturer, the water content in the steam is about 5 to 8 percent, compared with up to 40 percent for simple devices.
“Moist heat destroys microorganisms by irreversibly denaturing their proteins.”

Heat acts on microorganisms by destroying their proteins and enzymes. Among others, the US health authority CDC describes this: moist heat kills microorganisms through the irreversible coagulation and denaturation of their proteins. [Source: CDC]
This has also been measured on surfaces. In a study in the American Journal of Infection Control, saturated steam reduced the number of bacteria on frequently used surfaces by over 90 percent. [Source: Sexton 2011]
What matters is the right expectation: micro steam reduces germs with heat, entirely without chemicals. That is measured, and it is exactly what the machine is built for.
Three ways to get a surface clean. The difference is in the detail.
| Hot micro steam | Hardware-store steam cleaner | Chemical cleaning | |
|---|---|---|---|
| How it works | Heat and fine, low-water steam | Heat and steam | chemical agents |
| Residual moisture | low, fast drying (manufacturer's figure) | higher, wetter | wet |
| Chemicals needed | no, mostly just water | no | yes |
| Residue on the surface | none, water evaporates | none | chemical film possible |
| germ reduction | through heat (studies: over 90% on surfaces) | through heat, mostly lower | depends on the agent |
| Running costs | Water and electricity | Water and electricity | ongoing purchase of agents, packaging |
| Longevity | built to last decades, repairable | often short-lived | not applicable |
One device, one jet, the right attachment. With it you clean very different surfaces, at home and in the business.
The benefit has been studied especially for mattresses and upholstery. A study in Environmental Health Perspectives showed that steam cleaning reduces the house dust mite allergen in carpet, and does so longer lasting than vacuuming alone, up to eight weeks. [Source: Vojta 2001]
For businesses we have described the use by sector:
“Talk is cheap. You only see the difference when the steam works on your own surface.”

Many cleaning agents contain substances that can irritate the skin and airways. Preservatives like Methylisothiazolinon are considered common contact allergens and were named contact allergen of the year in 2013; they are found, among other places, in cleaners. [Source: DermNet] Anyone who cleans without such agents never brings them into the indoor air and onto the surfaces in the first place.
The environment cleans up too. Surfactants and other ingredients reach the waters via wastewater and can harm aquatic organisms, according to the German Umweltbundesamt. [Source: UBA] Microplastics deliberately added to cleaning and care products have been gradually banned in the EU since 2023. [Source: EU Regulation 2023/2055]
In many applications micro steam needs only water. No agent that goes into the wastewater, no empty plastic bottle.
Without cleaning agents there are no fragrances or preservatives.
What cleans with water alone does not pollute the waters.
No restocking, no packaging waste, no microplastics.
We do not gloss over things, we show what is proven:
Moist heat reduces microorganisms (CDC).
CDCSaturated steam reduced the germ count on surfaces by over 90% (Sexton 2011).
Sexton 2011Steam reduces mite allergen longer than vacuuming alone (Vojta 2001).

Frequently asked questions
Yes, in many applications plain tap water is enough. The heat dissolves grease, limescale and dirt, no cleaning agent needed.
No. Micro steam reduces germs through heat, this has been measured in studies. We do not promise germ-freedom or disinfection in the legal sense.
It does without the irritants and fragrances found in many cleaning agents. For mattresses, the reduction of mite allergen has been studied. What makes sense for you, we show at the demonstration.
No. In care, medical practices and food businesses the required, listed disinfection remains in place. Micro steam takes over the thorough cleaning and reduces the use of chemicals in everyday work.
Professional devices produce hotter, finer and lower-water steam. The result dries faster and the device is built for continuous operation and decades, not for a few years.
Not cheap, but good value. You buy it once and use it for decades. We discuss the price openly at the free demonstration.
