CASE STUDY: Soft Washing in Cardiff
LOCATION: Cardiff, Wales
WORK REQUIRED: Soft Washing
For many homeowners, pressure washing seems like the obvious choice for patio cleaning—until the noise and potential damage make them think twice. This was the case for a Cardiff homeowner who turned to soft washing as a safer, more effective alternative.
In this case study, we’ll explore how soft washing transformed her outdoor space, detailing the process and the impressive benefits it delivered.
Request
A homeowner in Cardiff contacted us with a clear request—she wanted her patios and window sills restored to their original condition. Over the years, grime, algae, and weather had taken a toll on her outdoor spaces. However, she had one important condition: no pressure washing.
Why? She was worried that the strong jets of a pressure washer might damage her patios and delicate window sills. She also didn’t want the loud noise of a pressure washer disrupting her quiet neighbourhood.
Her request was simple but challenging. She needed a cleaning method that was gentle yet effective, able to remove dirt without harming the surfaces. That’s where soft washing came in as the ideal solution.


Process
Soft washing is a cleaning method that uses a low-pressure system along with a special cleaning solution to remove dirt, algae, and other contaminants. Unlike pressure washing, it doesn’t rely on high force, making it a safer choice for delicate surfaces like patios and window sills.
1. Pre-Inspection
Before starting, we carefully inspected the patios and window sills. This helped us identify areas with heavy stains and check for any existing damage. By doing this, we ensured our method would be both safe and highly effective.
2. Specialised Cleaning Solution
We applied a specially designed cleaning solution to tackle algae, dirt, and other grime. This solution not only cleans the surface but also prevents algae and mould from growing back, so the results last longer.




3. Gentle Application
We used a low-pressure soft washing system to apply the cleaning solution gently. This approach protected the delicate stone on the windowsills and the patio surfaces, avoiding any risk of damage.
4. Rinse and Post-Treatment
Once the solution had done its job, we carefully rinsed the surfaces, leaving the patios and window sills looking clean and refreshed. Any leftover cleaning solution will keep working over time to improve the results even further.


Results and Key Takeaways
The patios and window sills now look clean, fresh, and vibrant, with no damage in sight. But soft washing offers more than just a visual upgrade.
- Long-lasting results: Soft washing keeps working even after the job is done. The chemical treatment continues to fight algae and grime over time, so the patios will keep improving and looking even better in the weeks after the service.
- Safe and gentle cleaning: Soft washing is perfect for delicate surfaces like window sills. The low-pressure cleaning method protects the stone, ensuring there’s no damage like stripping or erosion, which can happen with high-pressure washing.
- Quiet and non-disruptive: The process is surprisingly quiet, which was a pleasant surprise for our Cardiff client. Without the loud noise of a pressure washer, the cleaning went unnoticed by neighbours, making it ideal for residential areas.
- Eco-friendly cleaning: Even though soft washing uses chemicals, it’s designed to be kind to the environment. The cleaning solutions are biodegradable and carefully formulated to remove grime without harming plants or damaging nearby surfaces.
Soft washing was the perfect choice for this Cardiff homeowner, making her patios and window sills look like new without the risks of pressure washing. This gentle but powerful method gave great results right away and also provided long-term benefits, like continued protection and keeping the surfaces in good condition.
