GreenClean Pro Hard Surface Algae Remover Active substances: Nonanoic acid The active substance in GreenClean Pro, nonanoic acid, helps to remove algae and green material from hard surfaces by the destruction of cell membranes, preventing photosynthesis and other physiological processes. The results can be visible after only a few hours and are long lasting with some surfaces remaining free from algae for a number of months. 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 500 m2 in just one 15 litre knapsack. GreenClean Pro can be used twice per year at a rate of 1.8ml/m2 or 18l/ha.
