Maintaining a well-kept lawn requires more than just regular mowing; it requires taking proper care of the lawn mower itself, particularly the blades.

Over time, grass clippings, dirt, and debris can accumulate on the blades, reducing their cutting efficiency and potentially damaging the mower. Cleaning the blades regularly not only ensures a clean cut, promoting healthier grass growth, but also extends the life of your lawn mower.

In this guide on how to clean lawn mower blades, we will walk you through the steps to safely and effectively clean your lawn mower blades, helping you maintain a pristine lawn with ease.

What is Needed

A Pair of Work Gloves:

Before starting any cleaning process, it is important to protect your hands with a pair of work gloves. This will not only keep your hands clean but also prevent any potential injuries.

A Clean Cloth or Rag:

You will need a clean cloth or rag to wipe down the blades and remove any debris or residue.

A Cleaning Brush:

A cleaning brush with stiff bristles will help loosen and remove stubborn build-up on the blades.

A Bucket of Warm, Soapy Water:

Fill a bucket with warm water and add some mild dish soap to create a soapy solution for cleaning.

An Old Toothbrush:

An old toothbrush can come in handy for reaching tight spots and removing debris from hard-to-reach areas of the blades.

8 Simple Methods on How to Clean Lawn Mower Blades

Method 1: Preparation

Before you start cleaning your lawn mower blades, it is crucial to ensure your safety and the proper functioning of the mower. Begin by turning off your lawn mower and disconnecting the spark plug. This step prevents the mower from accidentally starting while you work. Next, put on your work gloves to protect your hands from sharp edges.

With your glove-covered hand, tilt the mower onto its side, being careful not to spill any fuel. Position the mower so that the carburetor faces up, preventing fuel or oil leaks. Once you have secured the mower, you’re ready to proceed with the cleaning process.

Method 2: Removing the Blade

Using a wrench or socket, remove the bolt located in the center of the blade. Keep in mind that some lawn mower models may have two bolts holding down the blade. In this case, loosen both bolts carefully before removing them completely.

Place the blade and its washer(s) in a safe place where they won’t get lost or damaged during cleaning.

Method 3: Scrape Off Debris

With your wire brush or steel wool, scrape off any grass clippings, dirt, and debris stuck to the blades. Pay special attention to any buildup between individual blades and around the edges.

Avoid using excessive force as this may damage or dull the blade. If the debris is difficult to remove, soak the blades in warm, soapy water for a few minutes to loosen it up before scraping.

Method 4: Wipe Down with a Rag or Towel

After scraping off as much debris as possible, use an old rag or towel to wipe down the blades. This step helps remove any leftover residue and ensures that the blades are clean and dry before placing them back on the mower.

The rag or towel can also be used to clean the surrounding area of the blade, including the underside of the mower deck.

Method 5: Soak in Soapy Water

For more stubborn buildup and grime, you may need to soak the blades in warm, soapy water for a few minutes. This method helps loosen and dissolve the debris, making it easier to remove with your wire brush or steel wool.

Be sure to dry off the blades thoroughly after soaking before placing them back on the mower.

Method 6: Sharpening

While cleaning your lawn mower blades is essential for maintaining a healthy lawn and prolonging the life of your mower, it’s also an excellent opportunity to sharpen the blades.

Using a metal file or grinder, carefully sharpen the blades by following the angle of the existing blade edge. Take care not to remove too much material while sharpening as it can affect the balance and cutting ability of the blade.

Method 7: Balancing

After sharpening, it’s essential to check and balance your lawn mower blades. Imbalanced blades can cause uneven cutting and vibrations on your mower, which can lead to damage or reduced efficiency.

To check for balance, place a nail or screwdriver through the hole in the center of the blade and see if it hangs evenly. If one side is heavier than the other, gently file down that side until both sides are balanced.

Method 8: Reinstallation

Once you have completed all the necessary cleaning and maintenance, it’s time to reinstall your lawn mower blades. Carefully place the blade back onto the mower, ensuring that it is secure before tightening the bolts. Be sure not to over-tighten the bolts as this can damage the blade or mower.

After reinstallation, turn your lawn mower back on and test its performance by cutting a small patch of grass. If everything looks and sounds good, then congratulations! You have successfully cleaned and maintained your lawn mower blades.
