Description
WD‑40 Smart Straw – 277 ml is a multi‑purpose lubricant and penetrating oil designed to protect metal from rust and corrosion, loosen stuck parts, displace moisture, and drive out moisture from electrical components. The Smart Straw feature lets you switch easily between a precision straw for targeted spraying and a wide spray for broader coverage. It’s ideal for use in workshops, homes, factories, and automotive applications to stop squeaks, free sticky mechanisms, and protect tools and machinery.
