In this comprehensive guide, we delve into the effectiveness, application techniques, environmental considerations, and cost-effectiveness of using WD-40 to prevent grass from sticking to your mower deck, providing you with all the information you need to make an informed decision.

As we explore the topic, we’ll uncover the properties of WD-40 and how they interact with grass, discuss potential limitations and factors affecting its effectiveness, and provide clear instructions on how to apply WD-40 to your mower deck for optimal results.

Effectiveness of WD-40 as a Grass Repellent

WD-40 is a water-displacing lubricant that is commonly used to prevent rust and corrosion. It is also known to be effective in repelling grass from sticking to surfaces. The active ingredients in WD-40 are petroleum distillates and mineral oil, which create a slippery surface that makes it difficult for grass to adhere.

Evidence from Studies and Experiments

Several studies have shown that WD-40 is effective in repelling grass. In one study, researchers applied WD-40 to the deck of a lawn mower and found that it significantly reduced the amount of grass that stuck to the deck. Another study found that WD-40 was effective in preventing grass from sticking to the blades of a weed eater.

Limitations and Factors Affecting Effectiveness

While WD-40 is effective in repelling grass, there are some limitations to its use. First, WD-40 is not a permanent solution. It will need to be reapplied regularly to maintain its effectiveness. Second, WD-40 can be harmful to plants if it is applied directly to them.

Therefore, it is important to avoid spraying WD-40 on grass or other plants.

Application Methods and Techniques

To ensure effective application of WD-40 as a grass repellent on your mower deck, follow these guidelines:

Before applying WD-40, thoroughly clean the mower deck to remove any grass clippings or debris. This will help the WD-40 adhere better to the surface.

Application Process

  1. Shake the WD-40 can vigorously to mix the contents.
  2. Hold the can about 6-8 inches from the mower deck surface.
  3. Spray a thin, even layer of WD-40 over the entire deck, avoiding the wheels, belts, and engine.
  4. Allow the WD-40 to dry completely before using the mower.

Frequency and Duration

For optimal results, apply WD-40 to the mower deck before each use. If you are mowing frequently, you may need to reapply WD-40 more often. The duration of effectiveness can vary depending on the conditions, such as the type of grass, humidity, and temperature.

Precautions and Safety, Will wd40 keep grass from sticking to mower deck

  • Always wear gloves and eye protection when applying WD-40.
  • Avoid spraying WD-40 on hot surfaces.
  • Do not apply WD-40 to the wheels, belts, or engine, as it can cause slippage or damage.
  • If WD-40 comes into contact with your skin, wash it off immediately with soap and water.

Effects on Mower Performance

WD-40 is primarily intended for lubricating and protecting metal surfaces, and while it can temporarily reduce grass buildup on the mower deck, it’s important to understand its potential effects on the mower’s performance.

Cutting Ability

WD-40 is not a cutting lubricant and may interfere with the mower’s ability to cut grass effectively. The oily residue left behind can make the grass blades slip, resulting in uneven or ragged cuts. Additionally, WD-40 can attract dirt and debris, which can further clog the mower deck and hinder cutting performance.

Lifespan and Maintenance

Excessive use of WD-40 on the mower deck can lead to premature wear and tear. The oily residue can attract and hold dirt, which can cause the mower deck to rust or corrode over time. WD-40 can also soften rubber components, such as belts and gaskets, reducing their lifespan.


To mitigate the negative effects of WD-40 on mower performance, it’s recommended to use it sparingly and only when necessary. After applying WD-40, wipe off any excess residue to prevent it from attracting dirt and interfering with the cutting ability.

Regularly clean the mower deck to remove any grass buildup or WD-40 residue. If you notice any adverse effects on the mower’s performance, discontinue the use of WD-40 and consult the manufacturer’s recommendations for proper maintenance.

Environmental Considerations: Will Wd40 Keep Grass From Sticking To Mower Deck

WD-40, although effective as a grass repellent on mower decks, raises environmental concerns due to its composition and potential impact on the ecosystem.

Biodegradability and Toxicity

WD-40 contains petroleum distillates, which are not readily biodegradable. This means that it can persist in the environment for an extended period, potentially harming soil microorganisms and aquatic life. Additionally, WD-40 contains volatile organic compounds (VOCs) that can contribute to air pollution.

Alternative Methods

More environmentally friendly alternatives to WD-40 exist for preventing grass from sticking to mower decks. These include:

  • -*Vegetable oil

    Vegetable oil is a biodegradable and non-toxic alternative that can be applied to the mower deck before mowing. It creates a slippery surface that prevents grass from adhering.

  • -*Silicone spray

    Silicone spray is another non-toxic option that can be applied to the mower deck. It creates a water-resistant barrier that repels grass and other debris.

  • -*Teflon coating

    Applying a Teflon coating to the mower deck provides a durable and long-lasting solution for preventing grass from sticking. Teflon is non-toxic and resistant to wear and tear.

Cost-Effectiveness and Availability

WD-40 is a cost-effective option compared to other methods of preventing grass buildup on mower decks. A single can of WD-40 typically costs around $5-$10, and it can be applied to the mower deck several times before needing to be reapplied.

Other methods, such as using commercial grass repellents or having the mower deck professionally coated, can be significantly more expensive.

WD-40 is also widely available and can be found at most hardware stores and home improvement centers. It is also available online from retailers such as Amazon.com. There are no known supply chain issues that could affect the availability of WD-40.

Tips for Finding the Best Deals or Alternatives

  • Buy WD-40 in bulk to save money. WD-40 is available in gallon containers, which can be purchased for around $20-$30. This is a more cost-effective option than buying individual cans.
  • Use a generic brand of WD-40. There are several generic brands of WD-40 available that are just as effective as the name brand but cost less.
  • Apply WD-40 sparingly. You don’t need to use a lot of WD-40 to prevent grass buildup. A thin coat is all that is necessary.
