The Environmental Benefits of Torc and DOFF Cleaning Techniques

When it comes to building restoration and surface cleaning, few methods are as effective and environmentally responsible as Torc and DOFF cleaning. At A Plus, we proudly use these systems to restore everything from heritage-listed buildings to contemporary properties, all while keeping sustainability at the core of our approach.

In this blog, we explore the environmental benefits of Torc and DOFF systems, and why they are the go-to choice for conscientious property owners and conservation teams alike.

What Are Torc and DOFF Cleaning Systems?

Before diving into the eco benefits, it helps to understand what these systems are.

• Torc cleaning uses a low-pressure swirl of fine granulate, water, and air to gently remove carbon staining, algae, paint, and biological growth. It is particularly suited to delicate stonework and historic facades.
• DOFF cleaning involves superheated water (up to 150°C) delivered at low pressure. This steam-based system is powerful enough to remove moss, algae, and graffiti – but gentle enough to avoid damaging substrates.

Both systems are approved by English Heritage and widely used on Grade I and II listed buildings, monuments, and church buildings.

Eco-Friendly Cleaning: Why It Matters

At A Plus, we believe building maintenance should not come at the cost of the environment. Unlike traditional pressure washing or chemical-heavy methods, Torc and DOFF offer significant eco advantages:

1. Minimal Water Use

While both systems use water, they do so very efficiently. DOFF uses low-volume steam rather than gallons of high-pressure water. Torc, meanwhile, uses a fine mist blended with inert granulates, keeping water consumption to a minimum.

Why this matters: Less water means reduced environmental impact and lower costs – ideal during periods of drought or in areas with water restrictions.

2. No Harmful Chemicals

Most traditional exterior cleaning relies on harsh biocides, bleaches, or acidic solutions. Torc and DOFF cleaning often need no added chemicals at all. When a treatment is required (such as for stubborn biological staining), we use eco-friendly, biodegradable products.

Why this matters: No chemical runoff into drains, soil, or watercourses – protecting wildlife and reducing pollution.

3. Protects the Building Fabric

These systems clean without eroding, scouring, or damaging the substrate. That means longer life for bricks, stonework, and renders – reducing the need for repair or replacement.

Why this matters: Lower carbon footprint over time due to fewer materials being needed and less waste being generated.

4. Quiet, Low-Impact Operation

Torc and DOFF systems produce less noise pollution than abrasive blasting or industrial pressure washing. This is especially important in residential or urban areas where noise disruption must be minimised.

Ideal for Historical and Modern Properties

One of the reasons conservation professionals trust Torc and DOFF is their ability to clean sensitively without damaging irreplaceable surfaces. From centuries-old sandstone to modern render and cladding, these systems adjust to suit the material.

At A Plus, we have used these methods across Hampshire and the South Coast on:

• War memorials
• Church buildings
• Town halls
• Modern rendered homes
• Commercial façades

Our experienced team always surveys each site and recommends the most appropriate, least invasive approach.

Certified and Trusted

We are trained in safe and effective use of both systems, and our operatives follow all relevant health and safety protocols. Our work is carried out in accordance with environmental best practice, and we ensure waste is properly collected, treated, or reused wherever possible.

A Greener Future for Building Maintenance

As the UK moves towards stricter environmental standards in the built environment, choosing sustainable cleaning practices is no longer optional – it is essential. Whether you manage a council property portfolio or a single heritage home, DOFF and Torc cleaning from A Plus helps you stay ahead of the curve.
