Biological products have been used in agriculture for years; biological cleaner emerged in professional pest management some years ago. Their use in the washroom environment has been a proven solution in Europe since the mid-1990s but only recently in Australia.
Originally designed as drain cleaners, they are now also being used to clean grease-covered surfaces in kitchens and dumpsters, and to eliminate odours that arise from organic residues. The same principle is used to treat uric salt contamination in washrooms and associated pipes.
Bacteria colonies grow and reproduce rapidly until the food source is eliminated. Vegetative bacteria then die; spore-forming bacteria remain dormant, ready to re-activate when more “food” is available.
The use of biological products with waterless urinals is now proven beyond doubt.
