Tornado Cleanze rapidly removes heavy black algae and lichen ("black spot")

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.

James Gibbon, C G Clean Down Ltd  

Heavy algae and lichen growth can be a problem to remove using conventional cleaning methods. Even regular soft washing 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

BEFORE TREATMENT WITH TORNADO CLEANZE

AFTER TREATMENT WITH TORNADO CLEANZE

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 or Perma Cleanze.
  
  
• Tornado Cleanze can be used as a topical cleaning product before or after applying Bio Cleanze and Lightning Cleanze, e.g for removing heavy black staining from 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 6 months after manufacture when stored in a cool location, in the original, unopened container.

Coverage

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".

Use de-mineralised* water if possible – as used for water-fed pole window cleaning – which will give the diluted solution a longer shelf life. Ordinary tap water can be used but the diluted solution should be used immediately. For best results use any diluted solution within 24 hours of diluting.

* In actual use this can be regarded as being the same as "de-ionised" water, although technically there can be subtle differences. The two words are often used interchangeably.

Quick tips:

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

We also suggest 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:

• concrete or stone window surrounds
• concrete or stone window sills
• concrete or stone wall capping stones

3) Use diluted 50:50 for relatively light 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.

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.

Application

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

Tornado Cleanze can be diluted and sprayed although this is not its intended use. A better practice in most instances would be to use Lightning Cleanze if a spray application is required (eg for treating large areas of wall render).

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 BY BRUSH

Ideally, apply in temperatures of 8-30 degrees C. Allow longer for Tornado Cleanze to work in cooler temperatures. Cool down surfaces by lightly pre-spraying with cold fresh water 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.

Important: Be sure to protect plant life from drops, accidental spillage and rinse water. 

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.

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 storage during hot weather.

• 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.
  
  Children and animals must be prevented from gaining access to the freezer and all other chemicals and chemical containers.

• Use a picnic cool box with an iceblock. These can often accommodate two 5 litre containers of Tornado Cleanze.

Health & Safety

• NEVER mix Benz Tornado Cleanze and Benz Bio Cleanze/Perma Cleanze together as toxic gas may be produced.

• ALWAYS thoroughly rinse application equipment before changing from Tornado Cleanze to Bio Cleanze/Perma Cleanze and vice-versa.

• EXCLUDE customers, the general public, children and animals from areas where application, mixing and storage of chemicals is taking place by erecting barriers and tape. And keep them excluded until the treated area has been made safe.
  

• Respiratory protection is not required when there is adequate ventilation, which is usually the case in outdoor environments. In poorly ventilated areas wear appropriate respiratory protection ( refer to SDS for the currently recommended type).
  

• Discharge rinse water in accordance with local by-laws and water authority regulations.

• If swallowed: Do not induce vomiting. Contact a doctor or medical specialist immediately. KEEP OUT OF REACH OF CHILDREN. Refer to the product SDS for specific guidance.

Safe working practices: When working with chemicals always keep your equipment and personal protection equipment (PPE) clean. Take care to protect yourself and the public from accidental contact with eyes and skin. Wear chemical resistant protective gloves, chemical resistant clothing that covers your whole skin surface, and a full face visor that includes protection for your hair. Wash all PPE with fresh water at the end of the working day and before eating, drinking, or smoking.

Always treat a small, obscure test area before using any chemical cleaning product. Obtain your customer's agreement that the result is acceptable and get their permission to continue before cleaning the entire property.
