A customer emailed us asking how to soft wash wet dash wall render without using a pressure/jet washer or harsh chemicals. He was wondering if Benz Bio Cleanze alone would do the job. And if so at what dilution ratio and should it be brushed in?
Apply Bio Cleanze at 30:1 by spraying and then brushing-in to make sure the biofilm is saturated. The render will continue to become cleaner through time by the natural action of sun, wind and rain.
You will see a dramatic improvement within two weeks, sometimes only a few days, when the red staining should disappear. And you will see another improvement at around two months when some of the black will have gone.
From then on it's a slow but sure process of continual cleaning over the next 6-12 months, by which time the surface of wet dash render will be mostly restored.
Treat wet dash render by spraying with Lightning Cleanze at 5:1, followed by a second coat brushed in at 4:1.
Rinse well and then treat with Bio Cleanze at 50:1 to ensure all spores are dead, to give ongoing residual protection, and promote further natural deep cleaning over time.
Much of the black staining will be gone once the wet dash render has dried out and the red staining will be gone in 2-48 hours.
Treat with Bio Cleanze and return to the job after a period of time, say from 2 weeks to 4 months (the longer the better) and use Lighting Cleanze to remove the dead biofilm, which will achieve a faster result than leaving it to nature alone.
A very heavy, well-established biofilm is easier to remove with Lightning Cleanze once it's been treated with Bio Cleanze and left for a period of time. This will reduce the need for multiple applications of Lightning Cleanze to get the wet dash render fully clean on the same day.
With some forward planning this approach is the perfect preparation for painting previously unpainted wet dash render.

We use pencil jets in our brushes because we've found they don't clog or break as much as fan jets.
In the case of the Gardiner 45cm brush we use four of them. We turn the pump down so the flow rate is acceptable and does not produce much run-off.
Flow control at the pole is still critical however. Click the link on this page to learn about the solution we've found to be so successful ...

Some customers have wondered why we add IPA (Isopropyl Alcohol) to Benz Bio Cleanze. So we thought we'd clear this up and clarify the situation once and for all.

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.
