We've been asked about the best way to soft wash red algae stains from render, stone and brick walls.
After soft washing, light red algae will go from wall in a few days in warm weather and up to two weeks in winter.
Heavy dark red algae can be problematic as it often has multiple layers of black algae underneath. So be prepared to give multiple softwash treatments.
Benz Bio Cleanze biocide – when used as a stand-alone softwash treatment at up to 20:1 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 soft washing the worst of the red algae with Benz Lightning Cleanze biocide at 5:1 dilution (go to 4:1 if test results indicate this to be necessary but take care and use full ppe because the softwash solution 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. Bio Cleanze will continue cleaning the red algae through time and impart residual protection against recolonisation.

Slippery decking can be dangerous as well as unsightly. Covered with biological growths such as algae, people can slip and break bones. And of course it is simply unpleasant to sit out on a filthy, mouldy, rotting decking that was erected to be a joy.
Softwashing wooden decking and other timber buildings and fences can be a huge market for softwashing contractor who knows what they are doing.

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 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.
