    For home and professional use

    This product worked very well indeed. This was our first experience using Tornado Cleanze. We chose to use it on quoins and coping stones. Both were natural sandstone. Adhesion and quality were paramount on this job – and we were not disappointed.

    "I had some very good results with Tornado Cleanze on a rendered wall – and the valuable roses at the base of the wall are still flourishing!" Adrian Brooks, Home Soft Wash


    Heavy algae and lichen growth can be a problem to remove using conventional cleaning methods. Even regular softwashing may not be fully effective, or provide sufficiently fast results.

    Tornado Cleanze is the solution. Tornado Cleanze easily, quickly and safely removes stubborn black, green, red and yellow staining from external hard surfaces.

    And its rapid, precisely targeted cleaning action means there's no overspray or spray drift onto surrounding properties and plants.

    What is Tornado Cleanze?

    Tornado Cleanze is a non-penetrating, very strong sodium hypochlorite gel that stays on the surface. This gives it a long contact time and a remarkable power to oxidise and remove the discolouration caused by micro-organisms.

    Simply brush on, leave for 15-30 minutes, and rinse – Tornado Cleanze acts fast!

    Where to use

    Tornado Cleanze can be used as a stand-alone cleaner on paths, patios, driveways, render, concrete, sandstone, capping stones, chimneys, brickwork, stonework, window sills, some plastics and most other exterior hard surfaces.

    It can also be used as a “spot cleaner” in conjunction with one of our other Benz softwash cleaning products.

    For example:

    • Tornado Cleanze can be used to prepare the surface of coloured or plain render before treating with Benz Bio Cleanze.

    • Tornado Cleanze can be used as a topical cleaning product before or after applying Bio Cleanze and Lightning Cleanze, e.g for removing black streaks on render.

    The actual sequence of use will depend on the severity and depth of the colonisation, how long it has been allowed to grow into the surface, and the specific requirements of each job and customer.

    Ongoing maintenance: To keep surfaces permanently clean all year around, it's important to post-treat with Bio Cleanze after thoroughly rinsing off Tornado Cleanze.

    Packaging & Shelf Life

    Tornado Cleanze comes in sturdy, drop-tested 5 litre containers. It remains usable for at least 3 months after manufacture when stored in a cool location, in the original, unopened container.


    Tornado Cleanze is made with 5% sodium hypochlorite at 12 Ph – giving it the focused power you need to clean those really tough surfaces - fast!



    Tornado Cleanze is a concentrated, ready-to-use gel. A little goes a long way. 1 litre will cover 6 metres2 of render or brickwork, 10 metres2 of sandstone, or 10 average capping stones.

    To treat light stains, Tornado Cleanze can be diluted 50:50 (i.e. 1 part Tornado Cleanze with 1 part water).

    When and how to dilute Tornado Cleanze

    The reason Tornado Cleanze is so advanced compared with other gel products is that it can be diluted and yet still retains its excellent "stickability".

    If possible, use de-mineralised water (same as used for water-fed pole – WFP – window cleaning), which will give the diluted solution a longer shelf life. Ordinary tap water can be used, but the diluted solution must be used asap, certainly within four days.

    Quick tips:

    1) A light pre-wetting of the surface to be treated makes application by brush or roller faster and easier.

    We also sugggest lightly pre-wetting a surface after prolonged dry periods and/or in very hot direct sunlight.

    2) Use undiluted for local application where there is severe colonisation/staining – for which a diluted solution would be less effective. For example:

    • windows
    • window sills
    • wall capping stones

    3) Use diluted 50:50 for green, red and light black stains on all other surfaces. This makes application, on large areas of render for example, quick and safe because the product remains a gel. Rinse just before the product dries.

    An undiluted application, on heavily soiled areas, after rinsing and still damp works well.

    4) When cleaning sandstone, a 50:50 dilution of Tornado Cleanze and water tends to work faster than when undiluted.

    5) For best results use Tornado Cleanze within 24 hours of diluting.

    By brush or roller, or a combination of both. Ensure a thin film is left on the surface.

    Quick tip: A light jet wash before applying is ideal but not essential. Loose dirt and debris must be removed to allow Tornado Cleanze to do its job on the ingrained stain, but this can also be achieved with a simple hosepipe and broom.


    Applying Tornado Cleanze-stone-path-algae-white-lichen-spots-dots

    Apply in temperatures of 5-30 degrees C. Allow longer for Tornado Cleanze to work in cooler temperatures. Cool down surfaces in very hot weather.

    Quick Tips:

    • If the surface is warm, pre-wet it with a light spray of ordinary tap water before commencing treatment. If very hot, continually dampen the surface during the activation period.
    • Because Tornado Cleanze is a gel, it stays where it’s applied, even on vertical surfaces such as render, and is slow to evaporate.
    • If the discolouration is particularly bad, gently agitate with a soft brush after 10-15 minutes.
    • Protect areas that could be affected by spillages, or run-off after rinsing, e.g. lead flashing.
    • Rinse thoroughly after activation.

    Black and green discolouration will disappear from most surfaces within 30-60 minutes in mild temperatures, longer in cooler weather. Heavy red stains may turn pink at first, then fade in 24-48 hours. Sometimes, a second application may be needed.

    Why Tornado Cleanze is safer and more effective than bleach mixes *

    • The special formula reduces chloramine emissions, which means there is no need for a masking scent. There is almost no smell compared to bleach/surfactant mixes.

    • It is safer because of the extremely low likelihood of the product coming into contact with surrounding properties, vehicles, people, animals, plants – and of course splashing onto softwash contractors themselves.

    • It is more effective than any bleach/surfactant mix because our highly specialised gelling agent ensures Tornado Cleanze sticks to surfaces longer, with zero run-off prior to rinsing. This increases the contact time with organic growths, ensuring maximum effectiveness in removing them.

    Keep Tornado Cleanze cool to extend its shelf-life

    • Vans get hot inside during the summer months, so remove the Tornado Cleanze container and place it in a shaded area on the site.
    • Metal and wooden sheds also heat up, so find a cooler location for long-term storage.
    • Use a an old insulated chest freezer to keep Tornado Cleanze cool, but not freezing, away from sunlight. This also ensures chemicals are kept away from children, pets and the general public.
    • Use a picnic cool box with an iceblock. These can often accommodate two 5 litre containers of Tornado Cleanze.
