Our Penetrating Oil begins working within seconds of application. It flows easily through any grime, dirt or rust along the lines of contact and loosens parts or other working mechanisms it contacts. AireSun Global Penetrating Oil is a nano-technology which quickly penetrates into oxidized material as a metal working fluid. It has a high viscosity which prevents further oxidization and is environmentally safe. It replaces “white oil” petroleum products where up to 50% of spray is released into the environment.
