Professional Softwash Cladding Cleaning

Benefits of Soft Washing

The modern, technologically advanced, process of soft washing reduces, and even eliminates, the need for jet – or pressure/power – washing in most situations.

Soft washing is the process of using eco-friendly chemicals and low-pressure water to clean Cladding.

Soft washing will not damage your Cladding. It's effectiveness depends upon the cleaning contractor having the skilled knowledge of how to use the correct cleaning product at the correct concentration ratio, using the correct equipment. 

Soft washing provides long-term exterior cleaning by using low pressure and specialized chemicals (like biocides) to kill mold, algae, and moss, preventing regrowth for years (often 3-5) and keeping surfaces cleaner longer than pressure washing. It's a safer, deeper clean for delicate surfaces (roofs, render, wood) because the biocides sanitize, sanitizing the source of the organic growth and offering a residual effect against future build-up. Annual or biannual treatments maintain results effectively and cost-effectively. 

Softwash Long Term Protection for 3-5 Years

Soft washing biocides provide long-term protection by

killing organic organisms—such as algae, moss, fungi, and lichen—at their root and leaving a residual film that prevents regrowth. 

How Biocide Protection Works

• Residual Action: Unlike bleach (sodium hypochlorite), which provides an instant clean but no lasting protection, biocides like DDAC (Didecyldimethylammonium chloride)penetrate porous surfaces. They continue to kill spores that land on the surface for months or even years after application.
• Self-Cleansing Process: Many professional biocides are "spray and leave" products. They work with natural weathering (rain and wind) to break down and wash away dead organic matter over several weeks or months.

Is Soft washing with biocide 

the best method for cleaning Cladding?

Yes, bleach can damage cladding if used incorrectly, primarily through discolouration and surface degradation. While sodium hypochlorite (the active ingredient in bleach) is a standard professional tool for "soft washing,"  bleach is often too strong or if used at improper dilutions for delicate surfaces like Cladding. 

How Bleach Can Damage Cladding

• Permanent Discolouration: Using bleach straight from the bottle or in high concentrations can cause patchy, white, or streaked finishes due to a pH imbalance.
• Surface Etching: As a corrosive alkaline solution, concentrated bleach can break down the surface chemistry, stripping away the water-repellent silicone layer that protects modern renders.
• Salt Residue: If not thoroughly rinsed, bleach leaves behind salt deposits (efflorescence). These salts attract moisture, which can actually encourage faster regrowth of algae and moss.
• Warranties: Using unapproved chemicals or high concentrations can void manufacturer warranties for products like Cladding. 

Steam cleaning Cladding

Steam cleaning ( Doff/Torc ) Cladding is highly effective for removing heavy carbon staining or paint, but lacks the long term residual protection against algae that biocides provide.

soft washing with a biocide is widely considered the best and safest method for cleaning modern exterior Cladding. 

Why hire professionals:

They have the necessary training, equipment, and safety protocols for effective and safe cleaning, especially for high-level or difficult-to-reach areas. 

Techniques:

Professionals may use advanced methods such as:

Soft Washing: This method uses superheated, low-pressure water to effectively remove stains and dirt without harming the surface. 

• Water-fed poles: These poles allow for safe cleaning of high-level cladding without the need for ladders or scaffolding. 

• Specialized cleaners: Professionals use products suitable for different cladding types, including pH-neutral detergents for zinc cladding.
