BIO CLEANZE 5L: 1x5 Litre

Bio Cleanze



  • Details & Features

    Bio Cleanze is a high-quality, professional-grade softwash solution that is approved by both the Irish Pesticides Registration & Controls Service (PRCD) for use in Ireland (Certificate number: 98070) and the Health & Safety Executive (HSE) for use in the UK (Certificate number: 9936).

    Key Features:

    • Kind to Surfaces: More cost-effective and gentle than power washing, Bio Cleanze can be used safely on a variety of surfaces.
    • Biodegradable: Fully biodegradable and does not bio-accumulate, ensuring it is safe for the environment.
    • pH Neutral: Gentle on surfaces, safe for use around people.
    • Non-Bleaching: Contains no bleach or acids, making it suitable for a range of applications.
    • Effective Control: Controls algae, lichen, fungi, and mould.
    • Wide Application: Harmless to all known building materials, Bio Cleanze is ideal for use on roofs, patios, walls, driveways, and more.

    Versatile Use:

    • As a Standalone Softwash Solution: Simply spray or brush on, then walk away—no rinsing required.
    • As a Post-Treatment for Power Washing: Can be used to enhance the results of power washing, keeping surfaces cleaner for longer.
    • Pre-Painting Primer: Effective in killing algae and mould spores before painting.

    Surface Compatibility:

    Bio Cleanze can be used on a wide range of materials:

    • Coloured and plain wall render
    • Sand & cement render
    • Brickwork
    • Natural and artificial slate roofs
    • Clay tiled roofs
    • Concrete patios & paths
    • Block paving
    • Painted surfaces
    • Tarmac drives and car parks
    • Timber decking, fencing, and sheds
    • Natural stone, including sandstone and granite

    Testimonials:

    "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! A truly fabulous job, and I highly recommend it." – Aoife Barry, Cork, Ireland

    Dilution Ratios and Coverage:

    • Winter Work: 1 litre of Bio Cleanze makes 40 litres of mix (40:1 ratio).
    • Summer Work: 1 litre of Bio Cleanze makes 50 litres of mix (50:1 ratio).
    • Coverage: 1 litre of mix covers approximately 4 square metres. Therefore, 40-50 litres of mix can cover 160-200 square metres.
    • Important: When surfaces will be accessed by children or pets, use a maximum dilution ratio of 50:1, and ensure surfaces are fully dry before access.

    Application Tips:

    • Avoid treating surfaces if rain is expected within 8 hours.
    • In extreme heat, wet surfaces before applying to reduce evaporation.
    • Best results are achieved at temperatures above 8°C.
    • For muddy or dirty surfaces, hose down first and brush in Bio Cleanze for maximum cleaning effectiveness.

    Safety Guidelines:

    • Never Mix with Other Chemicals: Do not mix with products like Lightning Cleanze or Tornado Cleanze, as this could produce toxic gases.
    • Proper Application: Ensure that treated areas are safe for children and pets by using the correct dilution ratio and allowing the area to dry completely before access.
    • Protective Gear: Wear appropriate personal protection equipment (PPE) such as gloves, face protection, and clothing that covers exposed skin.
    • Public Safety: Ensure barriers are placed around treated areas, and that children and pets are excluded from the treated zones until surfaces are safe.

    Coverage Factors:

    The coverage area depends on several factors, including:

    • The material being treated
    • Surface porosity
    • The severity of algae, moss, or mould growth
    • Environmental factors like surrounding trees and moisture levels
    • The length of time since the surface was last cleaned

    Available Sizes:

    • 1 Litre and 5 Litre containers are available. All containers are industrial strength, ensuring durability in on-site conditions.

    Storage and Shelf Life:

    • Optimal Storage: Store between 16-20°C for best results. Bio Cleanze has a shelf life of 2+ years in unopened containers.
    • Avoid Low Temperatures: Crystallisation may occur if stored below 10°C, but this is usually reversible when warmed.

    Delivery Restrictions:

    Due to shipping restrictions, Bio Cleanze cannot be delivered to locations such as the Isle of Man, Isle of Wight, Channel Islands, and Scottish Islands without prior arrangement. Contact us for more information on shipping to these locations.
