What is Benz Bio Cleanze?

Bio Cleanze is a potent commercial biocide for professional softwashing use only. It incorporates an extremely pure high-grade DDAC (Didecyldimethylammonium chloride) – the active ingredient that does most of the cleaning work.

This particularly pure grade of DDAC is also used to formulate many other products including disinfectants, cleansers and sterilants for:

  • The food and beverage industries.
  • Hospitals.
  • Household and industrial kitchens.
  • Veterinary and institutional applications.

Therefore it is also perfectly suited to use as a biocidal cleanser for exterior surfaces. In other words, if it's good enough for hospitals, food preparation and animal surgery, it's good enough to clean roofs, walls and drives.


We employ a leading international chemical company to manufacture Benz Bio Cleanze, ensuring the highest possible quality

Benz Bio Cleanze can be used in two ways

1.  As a softwash solution for cleaning external hard surfaces. Simply apply and let mother nature do the work. You’ll notice dramatic results within 14 days, with the full process lasting for several months. The longevity of the clean is far greater than that obtained from power washing or bleach. We recommend it’s use on surfaces for which power washing would be unsuitable.

2. As a post-treatment following cleaning by power washing. It will kill the algae spores and black and white dots (lichen) that will be left behind and that power washing alone cannot remove.

Power washing followed by a treatment of Benz Bio Cleanze vastly increases the longevity of the clean for minimal extra cost. It is especially cost-effective compared to sealing systems.

How to apply  Benz Bio Cleanze
  • Using a power washer detergent feed, apply after power washing to kill the remaining spores and vastly increase the longevity of the clean.
  • Spray, or sometimes spray and then brush. A backpack sprayer works fine.
  • Dilute in a bucket for small jobs.
  • Use a window cleaner’s water-fed pole. 25 litres of diluted mix will treat up to 200 square metres, so trolleys are a particularly effective delivery system.


Benz Bio Cleanze is highly concentrated and is designed for use only by professional power washing contractors, soft washing contractors, exterior cleaners, painters and decorators, groundsmen, window cleaners, builders, landscape gardeners, and similar trades. In essence if you are already working in a trade that involves the competent, safe, and responsible handling of industrial chemicals you can purchase and use Benz Bio Cleanze.

Applying Benz Bio Cleanze using a power-washer

Some of Ben's best results, and numerous referrals, have come from post power washing treatment with Benz Bio Cleanze.  He says, "I used to feel embarrassed seeing drives on my cleaning round I'd power washed only 6 months previous again black and dirty. Now I have a sense of pride in seeing them remaining clean long after my work. And this higher quality of clean is bringing me many referrals."

The key point here is to take the time to know your power washer's dosing ratio. Work it out at home using the same set up you would use on a job. Use a similar length "go hose", etc, as down-stream chemical injectors are affected by pressure.

Another option would be to add Benz Bio Cleanze direct to the water tank. This is ideal if you know how much water your water tank holds.

Correctly diluted Bio Cleanze will not adversely affect your equipment in any way.

Applying Benz Bio Cleanze using a backpack sprayer

Backpack application can be slow but the flip side is that it's precise and the correct dosage is easy to work out. Always wear chemical proof clothing and full PPE as backpack sprayers can be prone to leakage.

Applying Benz Bio Cleanze using a water fed pole system

Using a window cleaner's water fed pole system is a great way to try out softwashing with only a small extra investment.

The key is to have your system set up so that the pump can be switched from pure water to sucking from a drum with minimal time and mess.

A T-piece and valve is all that is needed on the suction side of the pump to achieve this.


General notes on applying Benz Bio Cleanze

Test before applying: Always test a cleaning chemical on a small, obscure area of the surface to be cleaned if you are not familiar with the effect of the chemical on that particular surface.

Applying to metals: The same advice to test before applying a cleaning chemical applies to metals. We recommend wetting metal surfaces before applying a cleaning chemical to prevent streaking.

Application Temperature: We recommend using Bio Cleanze at temperatures no lower than 7 degrees C, as results can be inconsistent below this point.

Why we use IPA in Benz Bio Cleanze

Including 10-20% IPA (Isopropyl Alcohol) gives our product several advantages over just a basic biocide:

  • It enables a full 50% of active ingredient to be diluted. Products made without IPA are limited to a maximum of 40% active ingredient.
  • Brings improved temperature stability in cold weather, preventing the thickening associated with non-IPA products.
  • The manufacturing process uses IPA, which maintains the solubility and stability of the active ingredient – DDAC.


Watch this short video for a simple explanation:


Btw: At recommended dilution rates, the very small quantity of IPA in the product as applied to a customer's property has zero effect on the silicone in, for example, wall renders and tarmac (even pure undiluted IPA has no lasting effect on silicone).

The purity of our active ingredient is guaranteed by our suppliers to be greater than 95% and is typically 98%. And the content of DDAC in the supplied product is typically 50-52% and never drops below 50%.

Why not use a cheap biocide?

There are many heavily diluted products on the market with names such as “Mossgone”, “Algae Away”, “Moss Terminator”, “Patio Clear”, etc. – and they claim to do a similar job to Benz Bio Cleanze.

But the truth is they are very weak and contain only 5-10% active ingredient, compared to the 50% active ingredient of Bio Cleanze. That means they are 90-95% water and therefore can be over 150% more expensive in actual use.

Also, it's important to be aware that cheap biocides contain a type of active ingredient that is affected by hard water, which Bio Cleanze is not. So the results from using these lower grade products can be extremely variable.

Under the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR) regulations, Bio Cleanze – and similar products with the same transport class and packing group  – should be supplied to the end user in 1 Litre bottles by standard courier, and in larger containers only by a specialised Hazchem courier.

The EU regulations permit transportation of up to 30kg or 30L of product in a works van or car without having any special insurance considerations. There are no land, sea, or tunnel restrictions in regard to these quantities.

So you can rest assured that you can transport these quantities of Benz Biocidal Wash in complete safety and within the letter of the law.

Health & Safety

  • Do not pour water into undiluted Bio Cleanze. Always half-fill your tank with water, add the required quantity of Bio Cleanze, then complete filling your tank with water.
  • NEVER mix Bio Cleanze and Lightning Cleanze as toxic chlorine gas may be produced.
  • ALWAYS thoroughly rinse all application equipment and tanks before changing from Bio Cleanze to Lightning Cleanze, and vice-versa.
  • The public, including children and animals, must be excluded by barriers, tape and warning signs from areas where spraying, mixing and storage of chemicals is taking place and must continue to be excluded from the working area until the area is made safe. If a human or animal comes into contact with a softwash chemical the area of skin contact should be immediately rinsed with copious quantities of fresh water.

  • Surfaces on which children and animals may walk should be treated with Benz Bio Cleanze at a maximum dilution strength of 40:1 – children and animals should be prevented from gaining access to the treated area until the surface is completely dry.
  • Wear appropriate respiratory protection if working in confined, poorly ventilated areas.

When working with chemicals always keep your equipment and personal protection equipment (PPE) clean. Take care to protect yourself from accidental contact with your eyes and skin. Wear chemical resistant protective gloves, and 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 before taking breaks, before eating, drinking and smoking, and at the end of each working day.

Always treat a small, obscure test patch on a customer's property before using any chemical cleaning product and obtain your customer's agreement that the effect of the applied chemical is acceptable before cleaning the entire property.
