Doff Cleaning is a safe way to clean substrates such as brick and stone without causing harm to the surface being cleaned.
We use high temperature steam to clean of pollution, algae, biological matter and even paint leaving the substrate smooth and more importantly clean.
The doff system just needs a water connection and the super-heated steam effectively removes the contaminant giving buildings a new lease of life.
Torc Cleaning is a system not to dissimilar to dustless blasting but with one main difference we use very fine media and the nozzle we use gives a swirling vortex action covering more surface area at low pressure very gently taking the contaminant from the substrate.
This is a system used a lot in heritage projects because it effectively removes the contaminant without really harming any substrate.
