In the world of exterior cleaning, a softwash system is a revolutionary method that has become increasingly popular for its effective and gentle approach to cleaning various surfaces. Unlike traditional power washing, which uses high-pressure water to blast away dirt, grime, and stains, a softwash system relies on a combination of low pressure and specialised cleaning solutions to achieve superior results.
This guide will delve into what a softwash system is, how it works, its benefits, and its applications, offering a complete understanding of this essential cleaning method.
1. Understanding the Softwash System
A softwash system is designed for delicate surfaces that could be damaged by the intense pressure of traditional power washing. It uses a mixture of water, biodegradable cleaning chemicals, and low-pressure equipment to clean surfaces effectively without causing any harm.
The key difference between a softwash system and traditional pressure washing lies in the pressure level. While power washing often involves water pressures between 2,000 and 4,000 PSI (pounds per square inch), softwashing operates at a much lower pressure, typically around 500 PSI or less.
This reduced pressure ensures that the surface is cleaned thoroughly without being stripped, scratched, or otherwise damaged. The focus of a softwash system is on applying a potent cleaning solution that can break down organic material like mould, mildew, algae, and dirt, while the low-pressure spray simply rinses it away.
2. How Does a Softwash System Work?
The process of softwashing involves a carefully formulated cleaning solution, typically consisting of surfactants, bleach or other mould-fighting chemicals, and water. These solutions are designed to target and eliminate organic growths like algae and moss, as well as dirt and stains, without the need for aggressive scrubbing or high pressure.
-
Application: The cleaning solution is applied to the surface using a low-pressure spray. The solution adheres to the surface, breaking down dirt, algae, and mould over time.
-
Dwell Time: The cleaning solution is allowed to sit for a specific period, typically 15 to 30 minutes, depending on the severity of the contamination. During this time, the solution penetrates deeply, attacking the root systems of mould and algae, which ensures that regrowth is significantly reduced.
-
Rinsing: After the appropriate dwell time, the solution is gently rinsed away with a low-pressure stream of water. This final rinse removes the debris and leaves the surface clean, often looking like new, without causing damage to the material beneath.
3. The Components of a Softwash System
A softwash system consists of several key components that work together to deliver efficient and gentle cleaning. These include:
-
Softwash Pressure Washer: This specialised pressure washer is equipped with a low-pressure pump that allows the user to spray cleaning solutions onto the surface without the high-pressure force used in traditional washing.
-
Chemicals and Detergents: The cleaning solution is a crucial part of the softwash process. Typically, it contains a blend of water, surfactants, and bleach or other mould-killing agents. These chemicals are biodegradable, ensuring they won’t harm the environment while being effective on stubborn organic growths.
-
Lances and Nozzles: The spray lance and nozzle are designed to deliver the cleaning solution evenly and gently. These tools provide precise control over the application of the solution and the low-pressure rinse.
-
Tanks: Softwash systems are often equipped with dedicated chemical tanks that allow the operator to carry and mix cleaning solutions easily. Some systems allow for the mixing of different chemicals, tailored to specific cleaning needs.
4. Benefits of Softwashing
There are several benefits to using a softwash system compared to traditional power washing. Here are some of the key advantages:
-
Gentle on Surfaces: Softwashing is ideal for delicate materials such as roof tiles, painted surfaces, wood, and masonry. High-pressure washing can strip or damage these surfaces, while softwashing preserves their integrity while effectively removing contaminants.
-
Long-Lasting Results: The chemicals used in softwashing not only clean the surface but also kill the underlying growths at the root, significantly reducing the chances of regrowth. This makes softwashing particularly effective for areas prone to algae, mould, or lichen growth.
-
Environmentally Friendly: The biodegradable chemicals used in softwashing are gentle on the environment. Unlike power washing, which may cause runoff that damages plants or animals, the solutions used in softwashing are designed to break down naturally and safely.
-
Cost-Effective: While the initial cost of a softwash system may be higher than traditional pressure washing, the results last longer, reducing the need for frequent cleanings. Additionally, the low-pressure nature of softwashing reduces the risk of surface damage, saving money on repairs or re-painting.
-
Improved Aesthetics: Softwashing restores the appearance of buildings, roofs, driveways, and other surfaces, leaving them looking vibrant and fresh without the risks associated with high-pressure cleaning.
5. Applications of Softwashing
Softwashing is incredibly versatile and can be used on a wide range of surfaces and structures. Some of the most common applications include:
-
Roofs: Roof cleaning is one of the most common uses for softwashing, particularly for removing moss, algae, and lichen that can damage shingles and tiles over time.
-
Building Exteriors: Softwashing is ideal for cleaning the facades of buildings, particularly those with painted surfaces, stucco, or delicate cladding materials.
-
Driveways and Patios: Whether concrete, brick, or stone, softwashing can remove dirt, algae, and mildew, restoring the look of your outdoor spaces.
-
Decks and Fences: Wooden surfaces like decks and fences can be prone to mould and mildew growth. Softwashing ensures these surfaces are cleaned without causing any harm to the wood.
-
Solar Panels: Softwashing can be used to gently clean solar panels without damaging the delicate surfaces, ensuring they continue to operate at peak efficiency.
6. The Future of Exterior Cleaning
The softwash system represents a safer, more effective way to clean exterior surfaces without the risks associated with high-pressure methods. It provides long-lasting results while protecting the integrity of surfaces, making it the ideal choice for homeowners and businesses alike. With its gentle yet powerful cleaning solutions, softwashing offers a sustainable, cost-effective, and environmentally friendly approach to maintaining your property’s appearance.
By understanding how a softwash system works and its many benefits, you can ensure your outdoor surfaces remain clean, protected, and looking great for years to come.
Whether for routine maintenance or special cleaning projects, softwashing offers a superior solution to traditional methods, providing excellent results with minimal environmental impact.
