Description
Product overview
With a full 50% active ingredient (DDAC), it targets the underlying biofilm responsible for common exterior algae species, including those that appear as red, green and black staining, as well as algae, lichen, fungi and mould, allowing surfaces to clean naturally over time and remain cleaner for longer.
Unlike aggressive cleaning methods, Bio Cleanze is kind to surfaces and more cost-effective than repeated pressure washing. Its non-bleaching, bleach-free and acid-free formulation makes it suitable for use on a wide range of exterior materials without causing surface damage.
Suitable surfaces
- Coloured and plain wall render
- Slate and tile roofs
- Concrete patios and paths
- Block paving and cobblelock
- Pebble dash and dry dash
- Painted exterior surfaces
- Tarmac drives
- Timber decking, fencing and sheds
- Natural stone, including sandstone and granite
- Brick
Bio Cleanze soaks into porous surfaces, targeting the micro-organisms responsible for ongoing discolouration rather than just surface contamination.
Key benefits
- Long-term residual protection that helps prevent rapid re-colonisation
- More cost-effective and less aggressive than repeated pressure washing
- Biodegradable, bleach-free and non-acidic formulation
- Does not bio-accumulate and is kind to treated surfaces
- Suitable for use as a post-treatment following Lightning Cleanze or power washing, or as as stand alone softwash biocidal treatment
How it works
Bio Cleanze has built-in residual biocidal action, helping to prevent rapid re-colonisation after treatment rather than delivering just a short-term cosmetic clean. This makes it particularly effective on porous exterior surfaces where biological growth can quickly return if only surface contamination is removed.
The formulation is fully biodegradable, does not bio-accumulate, and is pH neutral, making it safer for materials, operators and the surrounding environment. It is not affected by hard or mineralised water and can be used either as a stand alone softwash treatment or as a post-treatment following power washing or Lightning Cleanze.
Thanks to its low surface tension, Bio Cleanze soaks deep into porous surfaces, improving wetting and penetration to reach embedded micro-organisms rather than just surface contamination. This deeper action helps address the root cause of staining and discolouration rather than masking it.
Bio Cleanze can also be used as a pre-painting treatment to kill algae and mould spores, helping to improve coating longevity. It is effective on timber structures such as sheds, fencing and decking, where it can help control wet and dry rot by treating the biological growths that contribute to deterioration.
As a professional-grade product, Bio Cleanze is significantly stronger than biocides sold to the general public. When applied correctly, diluted appropriately, and allowed to dry fully, treated surfaces can be safely returned to use, including areas accessed by children and pets.
