DOFF vs. TORC Cleaning: Which Stone Cleaning Method is Best for Your Leicester Property?
When it comes to stone and masonry restoration in Leicester, Skill Stone offers expert cleaning solutions using the most effective techniques available: DOFF and TORC cleaning. Both methods are widely used for cleaning historic buildings, monuments, and delicate surfaces, but they differ significantly in their approach. This makes each one better suited for specific cleaning challenges.
In this article, we will compare the two cleaning methods, their benefits, best applications, and when to use each one.
What is DOFF Cleaning?
DOFF cleaning is a high-temperature, low-pressure steam cleaning system designed to gently remove organic growth, dirt, and paint from stone and brick surfaces. The system heats water up to 150°C and applies it as steam, effectively breaking down surface contaminants without damaging the substrate.
Key Benefits:
- Safe for Delicate Surfaces: Ideal for cleaning Leicester’s historic buildings, statues, and stone carvings.
- Environmentally Friendly: Uses only water, eliminating the need for harsh chemicals.
- Effective Against Organic Growth: Removes moss, algae, fungi, and lichen by killing spores to prevent regrowth.
- Graffiti and Paint Removal: Efficiently removes graffiti, oil-based paints, and surface coatings without leaving residue.
- Minimal Surface Damage: Unlike pressure washing, DOFF cleaning avoids erosion and surface abrasion.
Best Uses:
-
Heritage building restoration in Leicester
-
Graffiti removal
-
Paint stripping
-
Biological growth removal (moss, algae, fungi)
-
Stone and brick surface cleaning
What is TORC Cleaning?
TORC cleaning is a specialised system that uses a gentle vortex of low-pressure air, water, and fine mineral abrasives to remove deep-seated dirt, carbon staining, and pollutants from stone and brickwork. This method is particularly effective for tackling stubborn stains and industrial pollution buildup in Leicester’s urban areas.
Key Benefits:
-
Ideal for Heavy Staining: Effective at removing carbon deposits, soot, and smoke damage.
-
Non-Damaging to Historic Stonework: Uses a fine abrasive to clean without causing erosion.
-
Chemical-Free Cleaning: Uses natural minerals and water, making it safe for the environment.
-
Works on Intricate Architectural Details: Suitable for cleaning carved stone and delicate masonry features.
-
Restores Original Stone Appearance: Revitalises aged stone surfaces without causing discolouration.
Best Uses:
-
Historic building and listed structure restoration in Leicester
-
Removal of carbon staining and industrial pollution
-
Cleaning of war memorials and sculptures
-
Restoration of heavily stained stone and brickwork
DOFF vs. TORC Cleaning: A Side-by-Side Comparison
| Feature | DOFF Cleaning | TORC Cleaning |
|---|---|---|
| Cleaning Method | Superheated steam at low pressure | Swirling mix of air, water, and mineral abrasive |
| Best for Removing | Organic growth, graffiti, paint | Carbon staining, industrial pollutants, deep-seated dirt |
| Suitable for | Stone, brick, and masonry | Historic stonework, intricate carvings |
| Environmental Impact | Uses only water | Uses water and a fine mineral abrasive |
| Surface Damage Risk | Low | Very low, but requires professional handling |
| Recommended for | Heritage buildings, general surface cleaning | Heavily stained stone and pollution removal |
Which Cleaning Method Should You Choose?
Choosing between the two depends on the nature of the surface contamination and the material being cleaned:
-
Use DOFF Cleaning if: You need to remove organic matter such as moss, algae, lichen, or graffiti without damaging delicate surfaces.
-
Use TORC Cleaning if: You are dealing with stubborn carbon staining, industrial pollution, or deep-seated dirt that requires a more intensive cleaning process.
-
Combination Approach: In some cases, both methods may be used together to achieve optimal results, especially on large restoration projects in Leicester.
Conclusion
Both cleaning options are excellent solutions for stone restoration, but they serve different purposes. DOFF cleaning is ideal for biological growth and surface contaminants, while TORC cleaning excels at removing deep-set stains and pollutants. By understanding their differences, property owners and restoration specialists in Leicester can choose the right method for their cleaning needs.
