Product Description

A powerful product which kills moss as well as a range of organic growth such as mould, mildew, fungi and lichen on outdoor hard surfaces.

GREEN CLEAR PRO is formulated as a fast-working microbiological biocide which eradicates and removes green growth with ease. Furthermore it has the capability to help prevent regrowth and swiftly erase the growth of potential health hazards such as algae, mould and mildew.


  • Application must be on a dry surface, via watering can or sprayer, with a temperature between 8-20 degrees

  • Refrain from spraying if rain forecast within 24hrs of application

  • Ratio for application should be 1:10, otherwise 1:5 for areas of heavy contamination

  • For continued prevention, use approximately 1:20 ratio intended for application every 1-2 years

  • 5 litres will treat 100 - 125m when diluted 1:5 and 150 - 250m when diluted 1:10

Green Clear Pro functions as am organic matter remover and killer on the majority of outdoor surfaces including but not limited to patios, roofs and drives. Perceived by experts as the superior organic matter killer for asphalt and tarmac based surfaces. Without a doubt the best available roof green growth remover which is used extensively for roof cleaning throughout the UK and Ireland. Also provides an option to be used as an organic matter inhibitor to help prevent future growth on roofs, driveways and patios.



The container must be shaken well prior to opening. The Green Clear Pro product should be added to water in the container to ensure excessive foaming does not happen. Once again, mix thoroughly before application. If you are treating heavy moss, the growth should be brushed prior to treatment. For optimum results it is integral to guarantee a thorough saturation due to the fact various mosses are very compact and the product may have difficulty penetrating the stem structure

We recommend considering a second application to kill highly resistant organic growths as well as spores which may be dormant. This doubles up as a preventative to help delay any re-growth of organic matter. To retain a problem free surface, its advised to apply again every 1-2 years via brush and hose to agitate and rid of dead spores.

Can be used during all months of the year for the same purpose.

Does not contain bleach or acid.

Response from Alex

Q: How far will 25l go on a concrete tile roof with heavy moss. How long before moss comes back. My house is 6 years old. Can you use on a Polycarbonate conservatory roof?

Craig Wild

A: The GREEN CLEAR Pro is a concentrated product that can be diluted at 5-1 for heavily infested roofs. With coverage to 'saturation' of between 3-4m2 per litre. 1 x 25L will cover between 375-500m2. It can be used on polycarbonate, no problem. Hope that helps
