The Crucial Role of Soft Washing in Hospital Exterior Sanitising


The facade of a hospital is more than just an aesthetic consideration; it’s a matter of public health. Traditional pressure washing methods may provide a superficial clean, but SoftWashing ensures a safer and more lasting solution, especially crucial for hospitals.

Why Soft Washing Over Pressure Washing?

While pressure washing has long been the standard in exterior cleaning, it may not be the best solution for hospital exteriors. Think of it as mowing a lawn; what is cut will grow back even faster. Soft Washing, on the other hand, offers a longer-lasting clean, particularly effective on surfaces like render, cedar wood, cladding, and even flat rubber roofs.

The Shortcomings of Pressure Washing

In the UK, pressure washing has been the go-to method for years. However, this approach only trims organic matter, not eliminate it. The material will re-grow, often more aggressively, posing a health hazard and undoing any initial cleaning benefits.

The Science Behind Soft Washing

Soft Washing goes beyond mere surface cleaning. It tackles harmful organic matter at the root, sanitizing spores on the render, wood, and cladding. This method significantly delays regrowth, providing a clean and safe exterior for longer periods.

Reach New Heights Safely

For high-level hospital wall sanitising, Soft Washing employs a controlled stream that reaches up to 37 feet. Telescopic poles, elevated work platforms, and even abseiling provide options for hard-to-reach areas. The sanitizing solution is conveniently pumped from our specialised Soft Washing vans.

What Are We Up Against?

Organic matter manifests in various colors like green, red, blue, and even orange, marring the building’s appearance. These are not just aesthetic issues; many are forms of ancient Cyanobacteria harmful to human health.

Experience You Can Trust

Purple Rhino has an extensive portfolio of successful hospital sanitizing projects across the UK. Institutions such as Wexham Park, Blackburn Hospital, and Stoke Mandeville, among others, have benefited from our specialized sanitizing approach.


When it comes to hospital exterior sanitizing, SoftWashing presents a compelling case. It goes beyond cleaning to deliver lasting sanitization, essential for public health.

Yours sincerely

  • From my initial contact with Purple Rhino to the finish, their work was very professionally carried out. Their team arrived on the arranged date and completed the work to a very high standard. Also, at very short notice, they managed to carry out a large cleaning schedule over a weekend in order for the school to look it’s best for a visit by RIBA judges. This was safely completed while various areas were in use. Definitely a five star service and I would recommend this company.
