Built on Soft washing: The Specialist System Behind Blue Whale SWS

At Blue Whale SWS, soft washing isn’t just part of what we do – it’s the foundation of our business. From day one, we’ve invested in high-performance, American-made soft wash systems, built directly into our vans, and we’ve never looked back.

This professional-grade setup, combined with deionized water, is what sets us apart in the exterior cleaning world – delivering safe, reliable, and long-lasting results across Doncaster and surrounding areas.


What Makes Our System Different?

Our soft wash system was designed specifically for exterior cleaning professionals. Sourced from the U.S. – where soft washing is the go-to method for roof and render cleaning – this setup allows us to handle everything from homes to commercial buildings with ease.

We’ve refined our approach using:

  • Specialist soft wash pumps and nozzles
  • On-board deionization tanks
  • Low-pressure application techniques
  • Professional-grade biodegradable cleaning solutions

Why Soft Washing Works

Soft washing uses low-pressure water flow combined with cleaning agents to safely treat and remove moss, algae, lichen, and organic staining. It’s ideal for delicate surfaces that could be damaged by pressure washing, including:

  • Roof tiles and slates
  • Render and K-Rend
  • Fascias, soffits, and cladding
  • Conservatories and porches
  • Natural stone and decorative brickwork

By using deionized water, we’re also able to leave a streak-free, spot-free finish – perfect for glass, UPVC, and shiny surfaces.

1. Pressure Washing Has Been the Default

In the UK, pressure washing (or jet washing) has long been the go-to method for cleaning exterior surfaces. It’s simple, easy to access, and widely known. Many homeowners and even tradespeople aren’t aware that soft washing exists — or they think it’s just a low-powered jet wash (which it’s not).


2. Lack of Awareness & Education

Soft washing requires a bit of understanding – it’s more about treatment than just blasting dirt away. It uses chemical solutions to kill and remove organic growth like moss, algae, and lichen. Many UK customers just aren’t aware of the method, its long-term benefits, or how it’s actually safer for surfaces like render and roofs.


3. Specialist Equipment Costs More

Professional soft wash systems (like yours from the U.S.) aren’t cheap, and they require training and setup. A basic pressure washer can be bought from a hardware store, while soft washing is more of a professional service. So fewer businesses offer it – and fewer people know it’s an option.


4. Misconceptions Around Chemicals

There’s often concern around using “chemicals” on homes. But professional soft washing uses biodegradable, carefully dosed cleaning agents, many of which are eco-friendly and fully approved. Still, public perception around safety and environmental impact needs improving – and businesses like yours are helping to do just that.


5. It’s Still Gaining Ground

Soft washing is much more common in the U.S. (especially in hot, humid regions where algae grows fast). But in the UK, it’s starting to grow as more people see the damage caused by pressure washing – cracked render, lifted roof tiles, etc.

Why Wash It With the Whale?

We’re proud to be a family-run, Doncaster-based business that has grown by sticking to quality and customer satisfaction. Our specialist softwash setup has been there from the start – helping us build a reputation for reliable, friendly service and impressive results.
