Softwashing thatched roofs is a nice niche market that softwash contractors may like to explore, especially those who live in rural areas.
Treat with Benz Bio Cleanze, giving two good soakings at 20-50:1 (depending on the severity of the infestation) to allow it to penetrate deeply into the thatch. This will take care of the algae, moss and fungi which will be seen to be dead in around 48 hours. Natural weathering of rain and sun will continue to clean the roof over the following 12 months or so.
Click here to read an article that gives some good "how-to" advice for application (dry weather, dry roof for example).
The article states "The most suitable controlling agents against algae are quats (quaternary ammonium compounds - e.g. Bio Cleanze). This product has a pre-emptive effect as a wood preservative".
Quick tip: We do not recommend treating thatch with Benz Lightning Cleanze or Tornado Cleanze – or any other sodium hypochlorite mix – because the sodium hypochlorite (SH) could damage the reeds.
SH is used to destroy wood in pulp mills, so we strongly suggest not spraying it on a thatched roof. This is the same reason we do not generally advocate SH for cleaning wooden surfaces.
That said, occasionally treating wood with Benz Lightning Cleanze may be indicated. In these situations great care must be taken to protect the wood. Click here to read a Trade Tips article that explains how to softwash wood/timber
If you are concerned about knowing if the thatch needs replacing or treating, make friends with a local thatcher and have them appraise the property. If it needs replacing then they will get another contract for their time.
With the right person it could become a mutually profitable relationship by putting work each other's way.
No. Bio Cleanze contains IPA (Isopropyl alcohol) at 10-20% to enable the full 50% of active ingredient (DDAC) to be dissolved. Without this the limit is only 40% DDAC.
At the recommended dilution levels of 20-50:1 the amount of IPA actually applied to a surface is minimal. And even this rapidly evaporates.
IPA is not flammable when it is diluted with water by even as little as 5:1, so when applied to surfaces at 20-50:1 dilution there is zero fire hazard.

Quick tip: Most thatched properties will be listed, so check with the relevant authority that they are happy for you to treat with Bio Cleanze and obtain their written permmission before treating. The owners of thatched properties will almost certainly know the relevant authority to ask.
We hope this information is helpful.

PS: After completing the first softwash treatment, put your customer on a "Clean & Maintain" ongoing maintence programme. Customers will enjoy a permanently clean property and contractors will enjoy a steady stream of repeat business.
A win-win arrangement for both customer and contractor.

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 ...

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.

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.
