What Is A Softwash System?

Quick Answer: A softwash system is a collection of equipment used to prepare, dose, deliver and apply softwashing solutions to exterior surfaces. Systems vary from simple starter setups to professional Dosatron-based systems used by contractors for roof cleaning, render cleaning, cladding cleaning and wider exterior maintenance work.

What Is The Purpose Of A Softwash System?

A softwash system allows contractors to apply cleaning and treatment solutions safely, consistently and efficiently to exterior surfaces.

The exact setup will depend on the type of work being undertaken, the products being used, the application volume required and the contractor's level of experience.

A good softwash system should support controlled application, suitable chemical handling and professional working methods.

What Equipment Is Commonly Found In A Softwash System?

A professional softwash system may include:

Water supply
Chemical containers
Application hose
Spray gun or lance
Nozzles or application tips
Pump or dosing system
Dosatron or injector system
Personal protective equipment
Suitable cleaning or treatment products

The final setup should match the work being carried out rather than being copied blindly from another contractor.

Do All Softwash Systems Look The Same?

No.

Some contractors operate compact systems designed for smaller domestic work, while others use larger setups designed for commercial projects and high-volume applications.

A beginner working part time may need a very different system from a full-time contractor handling roof cleaning, render cleaning and commercial exterior cleaning projects.

What Chemicals Are Used In A Softwash System?

Softwash systems may be used with different products depending on the surface, contamination and job objective.

Common products discussed within softwashing include sodium hypochlorite, surfactants and biocidal treatment products.

What Is The Difference Between A Pump System And A Dosatron System?

Pump-based systems and Dosatron-based systems both deliver working solutions to the surface.

The main difference is how the solution is prepared and delivered.

A pump system often uses pre-mixed solution. A Dosatron system automatically injects concentrate into the water stream at a controlled ratio during application.

Can Beginners Use A Softwash System?

Yes.

Many contractors start with simple equipment and gradually expand their systems as their experience and workload increase.

The key is to choose equipment that matches the type of work being targeted and to understand how the system works before using professional chemicals on customer properties.
