Algae can be red, green, or black and will colonise exterior surfaces such as renders, concrete, timber decking, aluminium and so on.
A large build up of algae can look “grimy”, especially when it's dormant as then the colour often changes to black or brown.
Historically, pressure washing, or industrial bleach designed for sterilising milking parlours and swimming pools, has been used to remove the grime. However the algae spores remained and quickly recolonised.
This meant the grimy appearance reappeared after only a few short months, depending on the time of year.
This disappointed many property owners, especially as pressure washing can be very expensive. The net result was that some people began to leave cleaning their drives and paths until they got “really bad”.
Fortunately, by sterilising the surface by using a combination of Benz Lightning Cleanze followed by treatment with Benz Bio Cleanze, a 12-24 month application is usually sufficient to give year round cleanliness and freedom from re-growth.
Quick tip: It's important to remember that Bio Cleanze offers powerful long-term "Residual Biocide Protection" against re-colonisation by algae spores. (btw: sodium Hypochlorite, bleach, or pressure/power washing cannot offer this level of protection against re-colonisation)
We hope this information is helpful and inspires you to succeed in softwashing.

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.
