Gentle Cleaning with Vacuum Blasting
No high pressure, no water, and no chemicals
Monuments and historic building façades are unique witnesses of their time. Ornaments, natural stone, historic plaster, and stucco reflect the history of centuries. Yet environmental influences such as exhaust fumes, soot, dust, salt deposits, algae growth, and bird droppings can make even magnificent façades appear grey and neglected over time.
When the former brilliance is hidden beneath a layer of dirt, façade cleaning for heritage-protected buildings can be worthwhile—provided it is carried out using a technique that protects the material. This is exactly where a dry cleaning method without high pressure, water, or chemicals proves ideal, as it does not attack or damage the surface.
Why is façade cleaning of historic monuments so demanding?
For heritage-protected buildings, protecting the material and preserving value are top priorities. Aggressive or unsuitable methods can cause damage:
- High pressure can open pores, chip edges, or roughen surfaces.
- Water can penetrate deeply, mobilize salts, and promote staining or moisture problems.
- Chemicals can cause discoloration and attack sensitive materials.
For this reason, controlled and material-friendly cleaning is the best choice—especially for natural stone, historic plaster, and façades with delicate architectural details.
Surface-gentle façade cleaning for heritage buildings
with vacuum blasting technology
Tornado ACS cleaning technology offers all the advantages needed for careful monument cleaning. The vacuum blasting process works with negative pressure: dirt and deposits are loosened and simultaneously extracted. This ensures a particularly clean and controlled cleaning process—without unnecessary stress on the façade or the environment.
