Similarly, just because a chemical is called a biocide, or "quat" (quaternary ammonium) does not make it comparable to Benz Bio Cleanze.
Quats in general are broken down by the presence of organic matter, particularly proteins that adversely affect their activity. Benzalkonium chloride is a type of quat also known as BZK, BKC, alkyldimethylbenzylammonium chloride, ADBAC, or BAC. It is a class of low-grade cationic surfactant used in some cheap forms of quat products.
While quats like BAC (Benzalkonium Chloride) are particularly sensitive to organic matter the high quality twin chain quat of DDAC (Didecyldimethylammonium chloride) used in Bio Cleanze is far less susceptible.
Bio Cleanze is highly effective when used on surfaces that have been pre-cleaned to remove organic matter, although pre-cleaning is not essential (when softwashing roofs with Bio Cleanze for example).
When using quats to treat a surface which has not been pre-cleaned, it is essential that the product is a high-purity DDAC such as Bio Cleanze. It will soak into the surface and re-activate in contact with moisture, ensuring a thorough treatment.
BAC cannot do this because it de-activates immediately upon use and does not have a high tolerance to hard water, ionic surfactants and organic soiling.
This property of DDAC makes it more efficient and effective than BAC and provides the consistency of results demanded by soft washing professionals.
The pure DDAC in Bio Cleanze has a particularly high tolerance to organic soiling, hard water and to anionic residuals (chemically complex but essentially negatively charged ions that form hydrogen bonds with water and are forms of soaps), all of which can result in de-activativation of BAC, which does not have these properties.
Quick tip: the propensity of Bio Cleanze to have a high tolerance to previous soap residues (anionic residuals) means that it can be used following a treatment with Benz Lightning Cleanze.
This is not the case with low-grade biocides as the small amount of residual surfactant (soap) left behind by Lightning Cleanze – and especially the cheap "home chemistry" sodium hypochlorite solutions that use inferior surfactants – would inhibit the effectiveness of the biocide.
The adsorptive* nature of Bio Cleanze means it will bind to the surfaces on which it is applied and offer residual anti-bacterial activity. The fact that surfaces remain clean for longer following a treatment with Bio Cleanze is due is to the combination of pre-cleaning – power washing or treatment with Lightning Cleanze – and subsequent use of Bio Cleanze rather than a low-grade quat such as BAC.
This quality is essential for the successful implementation of the Benz "Clean & Maintain" ongoing softwash maintence system. BAC cannot be used to offer a Clean & Maintain service because its effects do not last long enough.
* The adhesion of atoms, ions, or molecules from a gas, liquid, or dissolved solid, to a surface.
Including a small quantity of IPA gives our product several advantages over the more basic biocides, even those that use a better quality quat than BAC:
Quick tip: At recommended dilution rates, the very small quantity of IPA in Bio Cleanze as applied to a customer's property has zero effect on the silicone in, for example, wall renders and tarmac (even pure undiluted IPA has no lasting effect on silicone).
There are many diluted products on the market. They claim to do a similar job to Bio Cleanze and at first glance may appear to be cheaper.
But the truth is they are very weak and contain only 5-10% active ingredient (which is often only BAC), compared to the 50+% active ingredient of Bio Cleanze. That means they are 90-95% water.
In practice, because Bio Cleanze is so heavily concentrated, it works out up to 150% less expensive than the so-called "cheaper" alternatives.
Is not affected by hard or mineralised water.
It is important in today's world to always use products that conform to EU, UK and Irish regulations. Not using government approved biocides could result in prosecution and a contractor's insurance being made invalid.
Benz Bio Cleanze is fully approved by both the Irish Pesticides Registration & Control Service (PRCD) and the UK Health & Safety Executive (HSE) for use in Ireland and the UK. And it conforms to the Global Harmonised System (GHS) for product labelling.
The particularly pure grade of DDAC used to create Bio Cleanze is also used to formulate many other products including disinfectants, cleansers and sterilants for:
The purity of Benz DDAC is guaranteed by our suppliers to be greater than 95% and is typically 98%. The content of DDAC in the supplied product is typically 50-52% and never drops below 50%.
We hope this article has helped clarify the reality regarding the most commercially effective and environmentally responsible DDAC biocide that is best suited for professional softwashing.

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.
