Superheated Water Cleaning: The Safe and Effective Solution for Stubborn Stains

For property owners and restoration professionals, superheated water cleaning has become a preferred method for tackling stubborn stains, biological growth, and paint removal. This technique, known as DOFF or Thermatech cleaning, offers a gentle yet highly effective approach to surface restoration. This guide explores what superheated water cleaning is, its benefits, and why it is the best solution for sensitive surfaces.

What is Superheated Water Cleaning?

Superheated water cleaning uses high-temperature steam (up to 150°C) at low pressure to break down and remove contaminants. Unlike traditional high-pressure washing, which can damage delicate surfaces, superheated water cleaning works through thermal shock and controlled pressure to loosen grime and coatings without causing harm.

What Can Superheated Water Cleaning Remove?

This method is highly versatile and can remove a range of contaminants, including:

• Algae, moss, and lichen from stone, brick, and cladding
• Graffiti and paint from historic buildings
• Carbon staining and pollution deposits from facades
• Oil, bitumen, and biological growth on external surfaces
• Chewing gum and dirt build up on pavements and public spaces

Key Benefits of Superheated Water Cleaning

1. Safe for Delicate Surfaces
   Unlike abrasive methods, superheated water cleaning does not erode or damage materials such as sandstone, limestone, or timber.
2. Highly Effective Without Chemicals
   Many traditional cleaning techniques rely on harsh chemicals, which can harm the environment. Superheated water cleaning uses only water, making it an eco-friendly choice.
3. Prevents Long-Term Damage
   Moisture trapped beneath surfaces can cause damage over time. Superheated cleaning minimises water absorption, reducing the risk of damp-related issues.
4. Approved for Historic and Conservation Areas
   Organisations such as Historic England and the National Trust approve DOFF and Thermatech cleaning for use on listed buildings and protected sites.
5. Removes Biological Growth at the Root
   The heat kills spores and bacteria, preventing the moss, lichen, and algae regrowth far more effectively than pressure washing.

Why Choose Superheated Water Cleaning Over Other Methods?

While there are several paint and stain removal techniques, superheated water cleaning is ideal for sensitive surfaces where other methods may be too aggressive. Traditional high-pressure washing can cause irreversible damage, while chemical treatments pose environmental risks. Superheated water cleaning balances effectiveness and safety, ensuring optimal results.
