The Simple WD-40 Hack That'll Keep Grass Off Your Lawn Mower Blades

There's nothing that screams summertime like the smell of fresh-cut grass. Depending on where you live, you might be mowing your lawn one to two times per week, or even more during peak growing season. With this much mowing, you're bound to have grass clippings accumulate on your blades, leading to reduced cutting efficiency and a less-than-perfect lawn finish. To prevent this buildup and ensure a cleaner cut, you can use WD-40 to keep grass off your lawn mower blades.

This hack is one of the ways you can use WD-40 to get the most out of your lawn mower. By spraying WD-40 on your lawn mower blades, you'll have a non-stick surface that ensures a cleaner cut, reduces the strain on your mower, and makes cleanup a breeze after you're done. Additionally, a coating of WD-40 will help prevent rust from forming on your blades and deck, a relatively common issue that often occurs when mowing wet grass. Luckily, you don't need to be a home DIY pro to tackle this hack — a few simple steps will have your mower ready for a perfect cut every time.

To keep lawn clippings from sticking, it's important to clean your lawn mower from top to bottom. You'll need to clear away any grass clippings, dirt, and rust that have accumulated, especially on the deck and blades. You can use a hose or a pressure washer to do this, and scrub with a stiff-bristled brush to remove any stuck-on mess. Make sure that everything is completely dry before continuing to the next step.

Next, you'll spray a liberal coating of WD-40 on the underside of the mower deck and the blades. While you can use the traditional WD-40 Multi-Use spray that you already have in your toolbox, choosing WD-40 Specialist PTFE Dry Lubricant or WD-40 Specialist Silicone Lubricant will provide a more effective and longer-lasting non-stick barrier against grass clippings. Again, be sure to let it completely dry — about one to two hours — before using the mower.

Depending on the type of WD-40 you use, you can get anywhere between one and four mows out of a single coat. It's a good idea to inspect your mower blades and deck every other mow to check for grass buildup. If you start to notice grass sticking to your mower again, it's time to start the process over and reapply the treatment. It's important to know that wet grass sticks to mowers more than dry grass, so if you're looking to get the most out of this genius tip for using WD-40 at home, mow when it's dry.
