A special liquid for the decomposition of synthetic, animal, plant-based and mineral oils and fats, aromatics and other hydrocarbons. The molecular structure of the pollution is broken down and converted into bacterial degradable mass. This strongly enhances decomposition without the presence of harmful residues. Can be used to extract oil and so on from stone, asphalt, concrete and other porous surfaces, but also for tank and soil cleaning. Can also be applied in ultrasonic cleaning.
