This system allows to clean every surface without any kind of damage for the substrate.
Water
Compressed air
A mix of inorganic salts
A protective varnish
The mixture of air, water and salts optimize the final result of the process. The mechanical action is obtained by an impact between solid and liquid particles (water and salts) mixed in a low pressure air flux.

Furthermore water helps dissolving the salts, with a direct cleaning action on the threatened surface itself.
These particular process could also be combinied with protective threatments and make possible to:
Avoid paint gripping used for graffiti
Protect the surface from atmospherical agents
Guarantee long lasting properties
