Chesterton 723(E) penetrating oil

Fast-acting, penetrating oil in a convenient aerosol can. Penetrates deep to loosen stuck nuts, bolts, and fittings without damaging metal surfaces. Thanks to its great capillary properties, penetrates where other penetrants can’t. The torque needed to loosen bits up is lower, because Sprasolvo removes all rust, scale, oxidation residue, tar, grease, and charcoal. Designed for optimal penetration, so there are no added lubricants, dehumectants, or anti-corrosive agents.
