What Is WD-40 Used For?
WD-40 is a multi-use product designed to displace water, prevent corrosion, lubricate moving parts and clean residues from metal, painted and plastic surfaces. Common uses include freeing seized bolts and hinges, protecting tools from rust, displacing moisture from ignition systems, removing sticker residue and tar, quieting squeaks in hinges and slides, and lubricating light-duty mechanisms. WD-40 is not a heavy-duty grease — for high-load, high-temperature or long-term lubrication, use a purpose-formulated lubricant.

WD-40® Multi-Use Product can be used upright or upside-down only. When the can is upright, the product will flow through the dip tube. When upside down, the product will dispense directly from the valve at the top of the can.
If a WD-40® Multi-Use Product is sprayed at a horizontal angle, or any angle that lifts the dip tube out of the liquid, then propellent can escape within seconds. This results in "out of gas", or liquid left in the can that cannot be sprayed out. Once a can is out of gas, there is no way to get the rest of the liquid out.
To maximise the use of all liquid from your WD-40 Multi-Use Product aerosol, follow the steps below.
In this article, we discuss three steps to remove all product from a WD-40 can:
- Shake can
- Spray upright or upside down
- Orientate the dip tube using the classic spray or smart straw
