Render Cleaning in Croydon
For property managers, block managers, concierge teams, apartment owners and estates. We also clean render on hospitals, hotels, schools, universities and homes.
Low pressure soft wash
Thermal imaging where helpful
Wastewater control and compliance
Safe soft washing that lasts
We clean render using the soft washing method that replaces pressure with chemistry and control. A carefully blended solution of sodium hypochlorite mixed with water and soap is applied at low pressure, only after a porosity test confirms suitability. This gets to the root of organic staining without damaging the surface.
- Porosity test and, where helpful, thermal imaging to inform the plan
- Low pressure application to protect thin-coat, monocouche and EWI systems
- Wastewater managed to protect drains and meet local rules
- Trained soft-wash technicians working to a documented standard

Why Soft Washing Is Safer for Render Cleaning
Soft washing is the safe alternative to pressure washing. Instead of blasting render with force, we use a low-pressure system that blends sodium hypochlorite, water, and a biodegradable surfactant.
Unlike pressure washing, soft washing won’t damage delicate finishes or drive water behind the render. It sanitises the surface and breaks down organic growth at the root — meaning cleaner walls that stay clean for longer.
The most common mix we use is 97% water, 2% sodium hypochlorite, and 1% soap — carefully adjusted based on the render’s porosity.
At Nautilus Clean, we use certified soft washing equipment and follow strict preparation protocols for every render cleaning project.
