Benz Bio Cleanze, Perma Cleanze, Lightning Cleanze and Tornado Cleanze are all suitable for cleaning natural stone, man-made stone, hard stone and soft stone.
We sell two softwash biocides: Bio Cleanze and Lightning Cleanze.
Benz Tornado Cleanze, acts as a "residual spot cleaner" which removes any remaining ingrained black, green, red and yellow staining (caused by algae, lichen, moss and mould) from stone, concrete, brickwork, uPVC and most other external hard surfaces.
Tornado Cleanze is particularly valuable for the softwash cleaning of vertical stone walls when you need a product that with "super-stickability" that will cling to the surface and not run off.

On the whole, for non-porous hard stone such as granite, you’ll find Lightning Cleanze and Tornado Cleanze produce the fastest and most effective results. And they are highly effective when used together in a "perfect synergistic partnership".
For soft, porous stone such as sandstone, Benz Bio Cleanze comes into it’s own as a post-treatment because it’s extremely good “wetting” characteristics – it's an even more effective wetting agent than water – allow it to soak deep down under the surface.
This enables Bio Cleanze to kill any remaining spores that may have remained deep within the permeable stone. It can also be used as a stand-alone treatment for hard stone such as granite. And it offers longer-term residual protection from re-colonisation than is possible when soft washing with a sodium hypochlorite product alone.
Black limestone can fade over time through exposure to weathering by sun and rain. It can become covered in algae which, when treated, exposes the faded limestone underneath the colonisation. And because of it's susceptibility to weathering, exposed areas of limestone can look dramatically different to sheltered areas.
Limestone often contains iron, which can turn black or orange and look unsightly. Sometimes limestone can look worse after soft washing. Fortunately, over time the limestone will usually fade back to how it looked before being treated.
Other factors to consider when soft wash cleaning limestone:
Quick tip: As with any surface and product you are not 100% certain will be compatible, always (with your customer's permission) treat a small, out of the way test area first.
A stone surface – whether natural stone or man-made stone, hard stone or soft stone – should not require re-treating for several months after being cleaned with Lightning Cleanze or Tornado Cleanze.
The time after which re-treatment with Bio Cleanze will become necessary is far greater, although because of the numerous variable factors it is impossible to quote a definite period.
The exact time-scale depends on the type of stone, the local environment, the care that your customer takes of their property, and the proximity of trees, bushes, plant pots, etc.
Quick tip: After the first treatment, remember to put your customer onto an ongoing scheduled "Clean & Maintain" programme, which will keep your customers happy by giving them a permanently clean property – and give you, the contractor, a nice repeat income.
We hope this information is helpful and sincerely wish you great success in your soft washing business,

Sealers are used in an effort to protect building materials. But do they inhibit the return of algae, moss and lichen? And can they lead to damp & mould?

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.
