We've been asked about the best way to softwash red algae stains from wall render.
After softwashing, light red algae will go from wall render in a few days in warm weather and up to two weeks in winter.
Heavy dark red algae on render can be problematic as it often has multiple layers of black algae underneath. So be prepared to give multiple softwash treatments.
Benz Bio Cleanze – when used as a stand-alone softwash treatment at up to 25:1 dilution – will clean red algae from wall render in a few months. A second application after a month or so is often advisable to remove any remaining red algae stains.
The fastest results come from softwashing the worst of the red algae with Benz Lightning Cleanze at 5:1 dilution (go to 4:1 if test results indicate this to be necessary but take care and use full ppe as it is getting quite strong at that dilution).
Then follow up with a treatment of Bio Cleanze, after thoroughly rinsing Lightning Cleanze from the wall render, at 40:1 dilution. Biocidal Wash will continue cleaning the red algae through time and impart residual protection against recolonisation.

In this video we install the water tanks. They will be used for window cleaning and for small soft washing jobs.
We also organise a storage system for our water fed pole brushes, upgrade the van interior lighting and start work on construction an internal ladder rack.

Several customers have asked about the difference between Benz Tornado Cleanze and Lightning Cleanze. The active ingredient in both (sodium hypochlorite) is the same, so why choose one product over the other?

We recently tested – just out of curiosity – some old Tornado Cleanze that was nearly two months past it's best-by date. We wanted to find out how long it could be stored for and still produce effective results. And stored badly at that ...

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.
