Penetrating oil in a spray. Flexible straw system, excellent for hard to reach places. Ideal for loosening rusted joints or fixings while providing lasting protection from corrosion. A hard-wearing, heat-resistant, flexible straw that can be used for a wide variety of applications. With the flexible applicator, you have two ways to spray; use the Flexible Straw for precision work and hard to reach areas, such as under sinks, inside chains, locks or rollers, then flip it down to use the wide angle spray for area coverage on surfaces. Whichever way you need to spray, you can rely on the clever 360 degree valve to work efficiently at every angle, including upside down. Easy to use, the unique formula dries quickly and leaves a thin, clear coating when you want to protect or lubricate a surface. WD-40 works just as well when you want to clean away stubborn residue.
