Get your lab coat with lots of pens in the top pocket. The initial clean is mainly done by fermentation extracts, enzymes and green surfactants. Fermentation extracts are produced by bacteria and added into our products to give that immediate cleaning action. Our highly biodegradable actives instantly lift dirt, oil or grease and grime from the surfaces. Simultaneously, our lab made fermentation extracts break down dirt and grime making them even easier to dissolve in water. Finally, our natural bacteria digest the newly dissolved grime, which eliminates residual odours and they continue cleaning days after the initial clean. We call them ‘a million little helpers’.
