How long can I store diluted Benz Bio Cleanze (DDAC biocide)?
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.
