Penetrating lubricant. Liquid wrench. It makes it much easier to disassemble rusted and corroded mechanical units and fasteners. The liquid wrench has capillary penetrating properties and easily wets rust, destroying the structure of the corrosive layer and releasing the parts for further dismantle. The liquid wrench penetrates through the oxydized metal and covers the surfaces with a thin lubricating layer, forms a film, which does not evaporate for a long time and protects fasteners from corrosion in future.
