WD40 PENETRATING OIL AEROSOL 400ML

Displaces moisture. It goes under surface moisture and establishes a protective barrier between the moisture and the parent metal. Penetrates and loosens rust-to-metal bonds, and frees stuck, frozen, or rusted metal parts. Protects against moisture and corrosion. Cleans dirt, grime, clotted grease and oil and at the same time forms a corrosion resistant barrier. Lubricates and will be widely dispersed and tenaciously held to all moving parts. Contains no silicones or other additives that attract dust and dirt causing a build-up of sticky, greasy residues.
