How long will a softwash treatment last?
No biocide can immunise the surface it is applied to from re-colonisation forever. Therefore re-treatment will eventually be necessary.
The spores that live in crevices, cracks, and roofing laps are killed. Their reproductive cycle is thus stopped, which means any re-contamination will be from new airborne spores or from water seeping in from contaminated areas.
Because Benz Bio Cleanze kills the original spores – and imparts a degree of residual protection from re-colonisation – its use results in surfaces that often stay cleaner 2-500% longer lasting than can be obtained from power washing alone.
Surfaces treated with Bio Cleanze will stay cleaner for longer even when they have first been treated with a powerful biocide such as Benz Lightning Cleanze, which produces a clean surface almost instantaneously and kills the spores (unlike power / pressure washing).
The residual protection offered by Bio Cleanze also means that surfaces will stay cleaner for longer after they have been treated with Lightning Cleanze. The two products work in tandem, each complementing the other.
Lightning Cleanze is often used on first cleans to remove the heavy build-up of colonisation by biological growths that has resulted from years of neglect. It offers a fast way to produce the clean surface customers want. Then a post-treatment with Bio Cleanze ensures the clean will be as long-lasting as possible.
The speed at which unwanted growths appear on a surface depends on the extent of it’s exposure to sun, shade, and moisture.
A fresh treatment, usually of Bio Cleanze, will be needed when growths return, and some, such as lichen, generally grow quite slowly. So re-treatment may not be required for a considerable time, sometimes several years.
Surfaces that do not self-drain, such as some paths and drives, and especially those that have areas of standing water, will be much more prone to faster re-colonisation by biological growths. These surfaces may need re-treating every 6-12 months to keep them perpetually free from colonisation.

Why pressure (jet, power) washing a roof is NOT a good idea
(Due to logistic problems associated with the government restrictions around Covid-19 this is a written, not video, Trade Tips post this week)
===========================
That's a reasonable question.
You could jet wash a roof and then treat with Bio Cleanze.
But why would you?
