Enclean® is a biocide or hard surface cleaner containing the active substance, nonanoic acid. Enclean can be used to remove algae and other green deposits from hard surfaces such as buildings, building materials, drives, roofs, paths, tennis courts, concrete, tarmac and block paving.

The active substance in Enclean, 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.
