A question our customers often ask: "What should I tell my customers who want to feel re-assured that the run-off from soft washing will not have a detrimental effect on our environment?"
Firstly, prevention is better than cure so reduce run-off at source by using skillful application techniques. Using the correct nozzles and flow rates will also significantly reduce run-off and therefore reduce risk.
Customers can be especially concerned if their property is close to a river.
The safest option if a property is close to a river would be to use Benz Bio Cleanze only, which will remain in the treated porous surface, offering long-term residual biocide protection from re-colonisation.
All residues from softwashing with Bio Cleanze are fully biodegradable without further treatment. And as this product should not be rinsed, there is no concern about rinse water entering drains or the river.
There's seldom an issue when treating with Bio Cleanze and the run-off is very slight.
Your customer would have to accept the longer timescale for results to show than if Benz Lightning Cleanze was used first to clean the worst of the contamination.
Lightning Cleanze does not bio-accumulate and it's surfactant is fully biodegradable.
Even so, run-off from Lightning Cleanze should not go into surface drains, which often lead into rivers.
The rinse water will only contain a small amount of common salt and organic residue. But it should be diverted to the foul water drain where it will be treated by the local sewage works.
Most properties have sewer access near the paths, so it's usually a simple matter to divert the rinse water into the foul water system.
Properties built prior to 1950 in the UK will probably only have foul water drains.
Quick tip: EU regulations allow for one-off discharges of some cleaning products into drains. It is the continual or regularly repeated discharge that harms the environment. The UK regs are usually similar but it would be wise to check.
Ask for permission from the water authority to dispose of rinse water into a surface drain. Quote regulation "ERC 8E" from the “REACH Use Descriptor System” when making your application.
IMPORTANT: Septic tanks and reed beds should never have any run-off or rinse water fed into them.
We hope this information is helpful and inspires you to succeed in soft washing.
Ben, Leo & Fiona,
PS: As legislation and building regulations are continually changing it would be wise to check with the relevant local authorities that our suggestions are acceptable to them, and ask if they want any additional procedures put in place. The information in this article and video pertains to EU and UK legislation and is our best understanding of the situation at the time of writing in August 2016.

We use pencil jets in our brushes because we've found they don't clog or break as much as fan jets.
In the case of the Gardiner 45cm brush we use four of them. We turn the pump down so the flow rate is acceptable and does not produce much run-off.
Flow control at the pole is still critical however. Click the link on this page to learn about the solution we've found to be so successful ...

Some customers have wondered why we add IPA (Isopropyl Alcohol) to Benz Bio Cleanze. So we thought we'd clear this up and clarify the situation once and for all.

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus, moss and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.
