When you’re working on equipment and something’s stuck, corroded, or just won’t budge, you reach for the blue and yellow can. This is the original WD-40 that’s been getting farmers out of tight spots for decades—the same formula that loosens rusted bolts, stops squeaks, and protects metal from moisture. The Smart Straw feature means you can flip between wide spray and precision stream without losing the little red straw.
What You’re Getting
- Smart Straw flips up for pinpoint accuracy or down for wide coverage—no more hunting for lost straws
- 5-in-1 formula that displaces moisture, penetrates rust, lubricates moving parts, removes grease and grime, and protects metal surfaces
- 8-ounce size that’s perfect for the toolbox or service truck without taking up too much space
- Works in temperatures from freezing to summer heat, so it’s reliable year-round
- Goes on thin to penetrate tight spaces, then provides lasting protection
Built for Real Farm Work
This is the stuff you use when the disc won’t fold because the pivot pins are seized, when the planter monitor cables are corroded, or when you need to free up a stuck grease fitting. It’s equally handy around the shop for loosening rusted exhaust bolts, protecting tools from rust, or getting squeaks out of equipment doors and latches.
Made to Last
The aerosol delivers consistent spray from the first use to the last drop, and the can won’t rust or corrode even when it’s been rattling around in a toolbox for months. WD-40’s proven formula has been trusted by mechanics and farmers since the 1950s because it simply works when you need it most.
Good to Know
The Smart Straw stays attached to the can, so you won’t lose it in the grass or have it fall into the engine compartment. Flip it down for wide coverage on large areas, or flip it up for precise application on specific bolts or fittings. Shake the can before use and wipe away excess product from painted surfaces to avoid streaking.
