A customer told us he'd soft washed red algae on a rendered wall with Lightning Cleanze, and was worried because areas of the render had turned pink, yellow or orange. So he asked us what he should do about the red algae changing colour so dramatically.
The change in colour of red algae is due to a brief and temporary flare up of the algae which happens naturally when it dies. Treated red algae will first turn pink and then go yellow or orange before disappearing completely. You will notice this more in hot weather.
The fact is this is perfectly normal and nothing to worry about. Red algae will often dry to a light yellow or off-white before becoming dramatically cleaner over the next 24 hours.
For example, after treating red algae with Lightning Cleanze the flare up will usually disappear within 2-48 hours. And after treating with Bio Cleanze the flare up will usually be gone once dry and will return to a similar colour as before treatment.
The natural weathering effects of sun, rain and wind will then will gradually remove the remains of red algae over the following days, weeks and months.Take a look at this short video. It has a time lapse sequence at the end showing the long term effects of treating render with Benz Bio Cleanze.
Quick tip: The most dramatic cleaning effect (the point whereby the customer is delighted with the results) will usually be noticed during a period of 7-14 days following treatment in warm weather and a couple of months in winter.
Some contractors do not understand the biology of soft washing and so, thinking there is something wrong, use very strong chemicals in an attempt to stop red algae flaring-up and changing colour.
The result is they sometimes do stop flare-up but at the expense of damage to the substrate, their equipment, our environment, the health of the person doing the soft washing – and anyone else, such as customers and the general public, who happen to be in the vicinity.
Fortunately, when a contractor understands the biology of what is happening they can use much safer softwash chemicals, which benefits everyone and everything.
It's crucially important to clearly and accurately explain to your customer, in advance of treating the red algae, what results they can expect to see, why, and when.
It's a sound business principle of good customer relations that when your customer understands what is going to happen – before it happens – the possibility of their being concerned about the colour changes is eliminated. And simultaneously their trust and confidence in you, the contractor, skyrockets.
We hope this information is helpful and sincerely wish you great success in your soft washing business,
Ben, Leo, Fiona, Stevie & Anthony

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.
