Is It Legal to Use Sodium Hypochlorite to Soft Wash?
Hello guys.
Last year I posted “has the bubble burst for the soft washing industry” Well I can categorically say it has not.
The last 12 months both Mr Clever Clean and SoftWash UK had been our busiest year yet.






Hello Chris,
Thank you for your message. Transitioning from high-pressure cleaning to soft washing can be a bit confusing with all the different mixes and products available. Let’s simplify things for you.
Firstly, to address the legal aspect: Yes, it is legal to use sodium hypochlorite for soft washing. It’s widely used in the industry for cleaning various surfaces, including render, slabs, and timber. However, always ensure you’re following local regulations and safety guidelines when handling and applying chemicals.
Key Products for Soft Washing:
Sodium Hypochlorite:
Purpose: It’s the most effective chemical for removing organic growths like green algae, red algae, and lichen.
Application: Typically mixed with water and a surfactant to enhance its cleaning power.
Clever Wash Surfactant:
Purpose: Helps the sodium hypochlorite solution adhere to surfaces and penetrate deeper, making the cleaning process more effective.
Mixing Ratio: Often used in a 1:1:1 ratio with sodium hypochlorite and water, but this can vary depending on the severity of the staining.
Biocide Soft Wash Pro 50:
Purpose: Acts as a preventative measure against future growth after the initial cleaning.
Application: Applied after cleaning to keep surfaces cleaner for longer.
Basic Soft Wash Mix:
For a versatile and effective cleaning solution, you can use the following mix:
Sodium Hypochlorite: 3 parts
Water: 6 parts
Clever Wash Surfactant: 1 part
Steps for Application:
Preparation: Ensure the surface is dry. Pre-wetting is generally not recommended as it can dilute the cleaning solution.
Application: Apply the mix using a soft wash system. Allow it to dwell for 10-15 minutes, but do not let it dry out.
Rinse: After the dwell time, rinse thoroughly with water.
