A stuck fastener is sometimes repeatedly heated, sprayed with penetrating oil, and then tapped with a hammer. If heating or hammering is not possible the penetration can be improved by first spraying brake cleaner on the stuck fastener and following with the penetrating spray before the brake cleaner has evaporated. The solvent penetrates better than oil and will pull some oil with it. |
