Penetrating oil spray and penetrants are low viscous fluids used in freeing mechanical parts such as fasteners that have rusted.

The liquid penetrates the metal pores and deposits an oil layer that causes any water present to be displaced, providing a protective layer against moisture. Penetrating oils and penetrants can also function as corrosion inhibitors or cleaning agents. (more…)
