Soft washing block paving paths and drives
We generally recommend lightly pressure washing block paving during the first clean (and only for the first clean). But pressure washing alone cannot kill the spores and so, if left untreated, the surface will re-colonise and look filthy again horrifyingly quickly.
Benz Bio Cleanze is the solution to this problem, as it rejuvenates paths and drives by killing the spores of black, green and red algae, along with mould, lichen, moss and most other biological growths.
So always follow up a pressure wash with a treatment of Bio Cleanze at 20-40:1*, which will kill the spores and continue deep cleaning over the following weeks and months.
Bio Cleanze imparts residual protection against re-colonisation, ensuring the path or drive stays cleaner far longer than would be the case with pressure washing alone, which is a great selling point for your softwashing services.
Put your customers onto an ongoing softwash property maintenance programme
Re-treat with Bio Cleanze every 6-18 months (depending on the local environment and tendency to re-colonise) to keep the drive permanently clean. Maintenance cleans can be at 40-50:1 dilution.
As long as the surface is kept clean by regular maintenance treatments there should be no further need for pressure washing. This is another BIG selling point for your softwash services. Let your customer know that you can give them a permanently clean drive, without them having to wait for it to get intolerably filthy before they do something about it.
Important: Apply sufficient mix to flood all the gaps, cracks, and crevices. This ensures all the spores are killed and therefore cannot re-colonise. Within a few minutes the biocide will have done its work and the algae and spores will be dead. Nature will cleanse the surfaces during the next weeks and months, washing away the dead algae and leaving a wonderfully clean path or drive.
Black or white dots on sandstone and concrete: These are black or white lichen and are usually so deeply ingrained that power washing alone will not shift them. But a treatment (sometimes two) of Benz Lightning Cleanze brushed in at 4-5:1 dilution will kill the lichen within minutes. This will loosen their roots and make it possible for a light pressure wash to remove them, after which the surface will look astonishingly clean.
Quick tip: For particularly severe infestations of lichen (often called "black spot") – especially when the lichen has been allowed to grow into the surface for a long period of time – we suggest treating with Benz Tornado Cleanze.
Then we suggest applying a post-treatment of Bio Cleanze at 20-40:1. This will delight your customer by continuing to cleanse the path, patio or driveway even more deeply and imbuing it with residual protection against re-colonisation.
Quick Tip: Bio Cleanze can be used as a surfactant that will help remove greasy marks. A weak mix can be used in a rotary surface cleaner, which then cleans more effectively than using water or most standard soaps.

*Important: If children or animals are likely to walk on the treated surface treat at a maximum dilution of 50:1 and ensure the surface completely dries out before they are allowed access.

Huge thanks to all our customers for your loyalty in making Benz your softwash product supplier of choice. We appreciate the fact that so many of our trade customers come back to us week after week, month after month, year after year.
And by way of practical appreciation, we've decided to no longer pro-actively seek domestic customers for our products and will not knowingly sell products to the customers of our trade customers, i.e. those who want to play around with d.i.y.

The good news is that there are ZERO customs duties to pay on Benz products.
Brexit has brought about many changes and challenges to business supply chains. And there's a lot of fear floating about regarding the excess taxes being levied on customers when ordering from EU-based companies.
So we want to reassure all our customers that we are able to continue supplying both our Irish and UK customers - with no additional duty, customs costs, or delays.
