Moss will normally start to appear around a new property after about 7 years. And it particularly loves to grow on tarmac and roof tiles.
On many buildings moss will start to grow on the roof, spread from the roof to the gutters, and then fall onto footpaths and drives.
And it can spread very quickly
Moss holds water, which can add weight to a roof – causing stress on the structure. It expands when frozen and can cause damage to gutters and tiles.
And it becomes extremely slippery on footpaths, driveways and playgrounds.
Tarmac will typically require two treatments of Benz Bio Cleanze in the first year to bring biological growth under control. Thereafter a once yearly application should be sufficient.
Concrete tiled roofs often last longer – sometimes as long as 5-10 years depending on the local environment and prevailing weather – before new growth becomes visible.
This is the legal situation concerning the use of softwash DDAC biocide to kill and control moss
Until June 2015 the active ingredient in Bio Cleanze (DDAC) was extensively used to kill and control moss, and was widely promoted as a moss control agent.
But the politicians and bureaucrats have decreed that moss is now a “plant” and therefore from this date comes under a different set of labeling regulations.
Yes, crazy though it may seem, all that changed to make it legally impossible for us to tell you that Benz Bio Cleanze kills and controls moss, was the movement of DDAC biocides to a different administrative category with different labeling criteria ...
Now, because of this change of legislation, only manufacturers of expensive herbicides (aka “weedkillers”), which are often quite unhealthy for humans and bad for our environment, can claim to control moss.
From June 2015 no DDAC biocide manufacturer is allowed to tell you that a biodegradable biocide such as Bio Cleanze kills and controls moss.
Fortunately, as the only thing that has changed is the labelling and legislative categorisation, everything else remains the same. This includes the effect on all unwanted biological growths such as moss, which we used to be able to tell you Bio Cleanze kills and controls, but are no longer allowed to tell you ...
Rest assured that the formula and contents of Bio Cleanze remains exactly the same as it was prior to the change of legislation – and you can therefore continue using it to kill and control all manner of biological growths on exterior hard surfaces such as drives, paths, car parks, tennis courts, roofs, walls, render, boats, decking and other timber structures such as sheds and fences.

Shadow, or "ghost" staining may sometimes remain after soft washing. Customers can misinterpret this as poor workmanship. But fortunately there's a simple solution that keeps everyone happy.

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.
