Description
GreenClean Pro Algae Remover
Active substances: Nonanoic acid
GreenClean Pro is a plant derived biocide hard surface cleaner which is an ideal solution to remove algae and other green deposits from pavements, greenhouse exteriors, buildings, patios, walls, roofs, paths, synthetic tennis courts, 3G and 4G sports pitches, tarmac, block paving, concrete, or wood, as well as street furniture, cemeteries, roofs, wooden decking, fence panels and playing surfaces.
GreenClean Pro contains 500g/l nonanoic acid which works by destroying cell membranes, preventing photosynthesis and other physiological processes. GreenClean Pro delivers fast and long-lasting results which are visible within just a few hours.
Unlike other de-greening chemicals which require large volumes of product and water, GreenClean Pro can be applied at low water volumes. In fact, just one litre of GreenClean Pro mixed with water will treat well over 500m2 in just one 15 litre knapsack.
GreenClean Pro can be used twice per year at a rate of 1.8ml/m2 or 18l/ha.
