The fact is that no sodium hypochlorite (SH) based softwash solution can, by itself, kill all the spores on, and in, a porous surface. And sodium hypochlorite offers zero protection against re-colonisation.
Benz Bio Cleanze on the other hand, because of it's enhanced "wetting" characteristics, seeps deeper into the surface, killing any spores that Benz Lightning Cleanze did not get to. Some of the active ingredient – DDAC – will remain in the substrate, offering residual protection against re-colonisation.
No hypo mix, pressure washing, or cleaning only with a surfactant can give this long-term biocidal protection.

Treating first with Lightning Cleanze kills off the vast majority of the spores, particularly those on the surface, and gives your customers what they want – a near instantly clean property.
It also means that Bio Cleanze has relatively few spores to kill, meaning that less of the active ingredient is used up in the initial treatment process.
Therefore, more of the active ingredient (DDAC) remains in the substrate, increasing the degree of long-term biocidal protection against re-colonisation.
Bio Cleanze completes a softwashing job, assuming your customer is willing to pay a little extra for the very best softwash treatment.
Of course if your customer only wants a quick clean before selling their property they likely will not want to pay for the increased long-term protection that Bio Cleanze offers. They simply won't expect to be in the property long-enough to enjoy the results.
To determine which softwash chemical to use, in what combination, at what dilution strength, it's necessary to appraise the needs of every contract on an individual basis.
When deciding on which softwash chemical to use, always take into account:

When soft washing it's vitally important to protect surrounding building materials. e.g. lead flashing. And not to create "clean streaks" – from overspray and run-off – on surfaces that are not part of your contract.

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.
