Softwashing is a cleaning method that uses low-pressure water combined with specialised cleaning chemicals to gently remove dirt, lichen, mould, algae, and other contaminants from surfaces. It’s particularly effective on surfaces such as roofs, patios, driveways, render and timber.
Softwashing chemicals are specially formulated cleaning chemicals designed to break down and remove stains, mould, mildew, algae, and other organic contaminants from surfaces. These chemicals are typically biocides or oxidisers.
No, softwashing chemicals are hazardous to the environment and the end user. This is why it is extremely important to follow the instructions on the label and familiarise yourself with the chemicals safety data sheet. Personal protective equipment should be worn at all stages of using the chemical.
Softwashing chemicals are suitable for virtually all surfaces, however, using the wrong chemical on an incompatible surface can cause permanent damage. This is why surface identification is key.
Softwashing chemicals work in different ways. Biocides puncture cell walls which cause cells to leak, this then leads to cell death. Oxidisers rapidly oxidise cells by introducing chemical compounds like chlorine.
This depends on the strength of the active ingredient of the chemical. New laws have been introduced restricting the sale of certain chemicals to the general public. All of our products are to be purchased by industry professionals only. You will have to show proof of your business and upload identification for certain PureSeal chemicals.
No. Most Softwashing chemicals are dangerous goods that fall into the class 8 (corrosive) category in ADR legislation. They also carry the hazardous to the environment pictograms on their container. These chemicals are designed to kill organisms upon contact.
When used properly, softwashing chemicals should not harm plants or landscaping. However, it’s important to follow proper application techniques and rinse thoroughly to minimise any potential impact. In some cases, covering delicate plants or watering them before and after cleaning may provide additional protection.
The effectiveness of softwashing chemicals can vary depending on the type and severity of the stains or contaminants being treated. In most cases, you may start to see results within minutes to hours after application. However, for heavily soiled or deeply embedded stains, multiple treatments may be necessary. Biocides have the longest cleaning cycle and can take 6 months upwards to self cleanse a surface.
When using softwashing chemicals, it’s important to wear appropriate protective gear, such as gloves and eye protection, to avoid skin or eye irritation. Additionally, follow the manufacturer’s instructions carefully, and avoid mixing chemicals unless specified. COSHH assessment of the chemicals you use in the UK are a legal requirement and can be compiled using the chemicals safety data sheet.
