Undiluted and unopened, the shelf life of Benz Bio Cleanze is at least 2 years.
If you know you are going to be left with some unused softwashing mix, the best water to use would be purified water (as used for window cleaning with water fed poles, aka de-ionised water).
This would not affect active ingredient in Bio Cleanze – DDAC (Didecyldimethylammonium Chloride).
Other than this, it's impossible to give a definite answer because the chemical make-up of water varies dramatically from area to area. Therefore we cannot know the mineral content of the water that any given contractor would use.
That said, we've stored 25 litres of Bio Cleanze diluted with tap water for a couple of weeks and it has worked fine.
On a hot day the speed of degradation may increase. And it's always best not to store chemicals in very hot vans or sheds.
Our best advice is simply to mix up the quantity of Benz Bio Cleanze you know you will use – which you will get better at judging with experience – and price in some wastage.
By pricing in a small amount of wastage you can ensure you will not be out of pocket even if there is some left over.
We hope this information is helpful and that it 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.
