Their applied MicroFoam science uses microscopic foam generated by their industry-leading formulation to remove dirt quickly and effortlessly in any conditions. The foaming formulation clings to the surface of the bike and penetrates microscopic holes within the dirt, quickly lifting particles away from the surface. All while leaving a dirt repellent finish which slows grime build up. Tru-Tension's formulation is completely Biodegradable and contains no harmful surfactants, salts, chemicals or acids.Unlike other cleaners which quickly evaporate or drip off, Monkey Juice is designed to cling to the surface.
