              Bio Cleanze is kind to surfaces and more cost-effective than power washing

              “Our paths were washed and treated with Benz Bio Cleanze in November 2013. Now 16 months on they are still immaculate and look like they were just done yesterday! There were no streaks like we used to have when we power-washed ourselves and no splashing on the plinth or walls. A truly fabulous job and I highly recommend it.” Aoife Barry, Cork, Ireland

                Historic buildings: Benz Bio Cleanze – along with Benz Lightning Cleanze – is a powerful and yet non-aggressive way to care for the surfaces of our historic properties. It contains no solvents or compounds that could adversely affect the materials or coatings used in these valuable old buildings.

                “I am truly impressed by just how clean the pavement slabs are in my drive. I got it cleaned last July and it is now long passed Easter – and following the winter weather it is still unbelievably clean. The products used to clean the drive are second to none, so gentle, non-abrasive but remarkably effective. I cannot recommend this product – Benz Bio Cleanze – highly enough."

                How to Calculate the Coverage of Benz Bio Cleanze

                Please note: We give the following information for those new to softwashing to have a starting point when calculating the amount of product that will be needed for a softwashing contract.

                In actual practice multiple factors need to be taken into account, such as the type of material being treated, the type of infestation, how long the infestation has been allowed to grow into the surface, and so on.

                In general ...

                1 Litre of neat Bio Cleanze makes 40 litres of mix for winter work (40:1) and 50 litres in the summer (50:1).

                1 Litre of mix will cover approximately 4 square metres. Therefore you can expect 40-50 litres of mix to cover 160 - 200 square metres.

                5 litres will clean approximately

                • Five average driveways and paths around a house
                • Or, three average gable ends
                • Or, the walls of one average house
                • Or, one average roof

                Obviously, bear in mind that in reality there is no such thing as an "average" property or an average surface. We give the above information – and the data in the application guide – so that those new to softwashing can get an approximate idea of the area Benz Bio Cleanze can cover.


                Application guidance

                • In extreme heat, it is often a good idea to lightly wet the surface to cool it down before applying Bio Cleanze (to minimise "boil off").

                • Best applied in temperatures above 8 degrees C (results can be inconsistent below this point).
                • Dilution ratios: Can be applied from 25:1 to 50:1. Use higher dilutions for the more badly infested surfaces. Do not apply at higher than 50:1 if children and animals will walk on the surface, and allow the surface to dry completely before they are allowed access.

                Quick tips:

                1) Surfaces vary in porosity – including concrete slabbed paths and patios, brickwork, block drives, wooden sheds and fences – and therefore the cleaning effect of a Bio Cleanze softwash treatment may also vary. This can be especially true for concrete paths and patios that have had their surface layer damaged by high pressure jet washing.

                2) On areas of heavy algae growth, particularly on very porous surfaces when applied at 50:1:

                a) A second treatment after two weeks may be needed
                b) Using a soft brush to work Bio Cleanze into the algae will speed up the cleaning process and make the treatment more effective

                Container sizes

                You can purchase Bio Cleanze in 1 litre and 5 litre containers.

                NOTE: Benz containers are industrial strength and have been drop-tested. This means they can withstand the sometimes harsh conditions of on-site use, and storage in vans along with other equipment, without splitting.

                Some companies cut corners by supplying weaker containers to make their products seem cheaper. But we believe that the potential health and safety hazards these create, along with the financial cost of leakages, mean they are a false economy.


                • For best results store at approximately 20 degrees C (room temperature).
                • Always store Bio Cleanze in the original containers.
                • Shelf-life is 2 years or more after manufacturing date, when stored in unopened original containers.

                Health & Safety Guidelines
                • NEVER pour water into undiluted Bio Cleanze. Half-fill your tank with water, add the required quantity of Bio Cleanze, then complete filling your tank with water.
                • NEVER mix Lightning Cleanze and Bio Cleanze together as toxic chlorine gas may be produced.
                • ALWAYS thoroughly rinse application equipment and tanks before changing from Lightning Cleanze to Bio Cleanze and vice-versa.
                • ALWAYS exclude the public, including children and animals, from the working area 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 it 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.

                • Contractors should ask their customers if children or animals are on the premises, and advise them on protection procedures, before starting work on their property. Click here to read our guidelines for the safety of children and animals when softwashing with a biocide

                • Surfaces used by children and animals should be treated with Bio Cleanze at a maximum dilution strength of 50:1. Children and animals must be prevented from gaining access to the treated area until the surface is completely dry

                • All pooling must be brushed away or removed from the site – and all treated areas (including roofs and window ledges) allowed to completely dry – before allowing children and animals access to the surface.

                • If working in confined, poorly ventilated areas always wear appropriate respiratory protection (type stated on the Bio Cleanze SDS).
                  • The purchaser and end users are responsible for ensuring that our products are used in line with industry Approved Codes of Practice. All operators must be competent in using and applying our products. Always read and comply with the instructions for use on the label, and product information on this website, before use. The purchaser and end user of these products are responsible for complying with the PRCD/HSE code for the safe use of chemicals.

                  Safe working practices: 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. We recommend wearing protective gloves, 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 test area on a customer's property 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.
                  Always adhere to the SDS. Follow the product labelling instructions, and the product information supplied on this website, to ensure protection of our environment and avoidance of injury to humans and animals.
