Steam cleaning technology is not new. It has been known of for 150 years. Unfortunately it is not generally used.
Over the years the technology has become more and more popular, especially in the United States. It is now becoming more popular in Europe.
Dry steam contains only 5%-6% water so when you use it is very organic. The low moisture vapour makes it possible to use it in places and spaces where there is no waste water drain installation.
The advantage of this technology is that one process is used surface cleaning, disinfecting and removing any odours.
