In 2019, Foamstream was approved for use as an organic biocide in North America and the European Union and was proved to be highly effective at killing Hepatitis C, as well as other harmful viruses.
In light of the coronavirus outbreak, we understand that local towns, councils and other organisations are doing the best they can to ensure their constituents remain safe and healthy. In order to keep public spaces clean, you might be considering the best way to minimise the spread of pathogens and looking at solutions which don't simply move germs from A to B as can often occur with methods such as pressure washing.
What is Foamstream Clean?
Foamstream Clean is an efficient method of deep cleaning and sanitising your public spaces in an environmentally friendly and cost-effective way. It is safe for use around people, animals and delicate environments, and is a versatile piece of equipment that allows the user to switch effortlessly from weed control to cleaning and sanitisation (among other applications).
How does Foamstream Clean work?
The active ingredient in Foamstream is the heat delivered by the hot water; both pathogens and weeds are organic compounds that can be damaged by heat. By using Foamstream’s patented low-pressure process which combines heat with our biodegradable foam, users will have the unique ability to maintain critical heat on the target pathogens long enough to neutralise them.
Foamstream implements a contact temperature of around 95°C/203°F. Following this initial contact, the insulation qualities delivered by the foam enable the heat to stay above 57°C/135°F for 15 seconds - this is what neutralises the pathogens. The minimum levels of temperature and application time to kill varying harmful viruses are outlined in the table below:
The current municipal practice for dealing with pathogen control is mechanical, which involves using large cold pressure washers. Unfortunately, the effect this has on any unwanted germs is that it simply moves them from A to B, contributing to the wider transmission of these germs. Unlike pressure washing systems, Foamstream offers a lower-pressure solution with an elevated temperature, meaning that it can effectively first clean, then sanitise the targeted area, decontaminating it.

Using Foamstream to minimise the spread of COVID-19
The following table shows the persistence of similar strains of virus akin to COVID-19 against different types of surfaces. The virus can remain active for a significant amount of time on some common outside surfaces like steel, metal, wood, glass of plastic. These materials are very common on vehicles, street furniture, bus stops, outside of buildings etc. hence the absolute necessity of disinfecting them.

What public spaces can Foamstream clean?
- Flat surfaces including but not limited to benches, sidewalks, vehicle hoods, tombs, rubber grounds, bins, cigarette disposals.
- Vertical surfaces including but not limited to: park benches, vehicle sides, windows.
This lance is our highest-pressure lance (20 bar/290 psi). Despite being lower pressure than conventional ‘high pressure’ solutions, Foamstream achieves a more effective treatment result due to its prolonged high temperature delivered by an insulating foam blanket which reduces surface damage. It can be used for gum removal, removal of dirt and general surface grime where our softer bristled lance is not suitable.
Rotating nylon brush lance
This rotating lance is made from soft nylon bristles and is suitable for cleaning more porous surfaces which have built-up layers of debris where the pressure lance is not suitable. It can be used on wooden surfaces e.g. benches, wood panelled buildings, painted railings/surfaces, hard to reach corners, step fronts etc.
Nylon scrub brush
A more traditional rectangular brush head, this lance is perfect for cleaning tasks such as removing moss, algae or debris from smooth metal or plastic surfaces such as signs and bins. It can be used on street signs, street furniture, playground furniture or where a large surface area needs to be cleaned quickly.
This lance uses minimal heat retention due to the high pressure spraying nozzles creating droplets. As a result, there is less foam creation, meaning it is ideal for cleaning pavements efficiently.
