Do Benz softwash biocides stay in the soil? (video how-to)
Some of our softwashing contractor customers asked if our softwash biocides stay in the soil.
Clearly this is an important concern as we are all becoming more environmentally aware.
And it is important that softwashing contractors can speak clearly to their customers about this important topic and give them the facts about the environmental impact of softwashing.
Here's our video response: (scroll down for our written response)
And here's our written response:
Benz Bio Cleanze is fully biodegradable and complies with EU regulations for biodegradability. It biodegrades on contact with organic material, so will definitely not stay in the soil.
We've run long-term tests on lawns and flower beds to determine the effects of our biocides on plant life.
Test results show that Bio Cleanze has no detrimental effect on plant life when applied to surfaces at our recommended dilution rates, and when the soil and plants are pre and post drenched with fresh water.
Benz Lightning Cleanze does not bioaccumulate and breaks down into oxygen and a small amount of common salt on contact with organic material. Even the surfactant is fully biodegradable.
Although frequent applications, together with allowing run-off to enter the soil, could theoretically increase the salt content of soil, in practice this is unlikely to be a problem.
This is because Lightning Cleanze is mostly used as a one-off treatment, followed by regular maintenance applications of Bio Cleanze.
Run-off and spray drift from Lightning Cleanze has not been observed to have detrimental effects on lawns and flower beds when used at our recommended dilution rates and in conjunction with pre and post drenching of soil and plant life.
Our research tests of applying pure salt to soil over periods of several months has shown that a large quantity of salt is required to adversely affect the majority of plant life.
The practice of pre and post drenching dilutes the minute amounts of salt produced by the biodegrading of Lightning Cleanze.
This renders it effectively harmless. And of course rain will further dilute any remaining salt residue.
