Benefits of Maintaining a Clean Lawnmower

Keeping your lawnmower clean has many benefits. Not only does it improve the overall appearance of your lawn, but it also helps to extend the lifespan of your mower and ensures that it continues to function properly.

Improved Performance

A dirty lawnmower can affect its performance in several ways. Grass clippings, debris, and dirt can clog up the blades and air filters, making it harder for the mower to cut through grass efficiently. This can result in an uneven cut or cause the mower to stall frequently. By regularly cleaning your lawnmower, you can ensure that it continues to operate at its best and saves you time and effort in the long run.

A Dirty Lawnmower Can Affect Its Performance

Prevents Rust and Corrosion

Exposure to grass, dirt, and moisture can cause metal parts of your lawnmower to rust and corrode. Over time, this can lead to damage that is expensive to repair or even render the mower unusable. By cleaning off any debris and drying the mower after each use, you can prevent rust and corrosion from occurring.

Increases Safety

A clean lawnmower is a safer lawnmower. Grass clippings, debris, and dirt can pose a safety hazard if they get caught in the blades or around moving parts of the mower. By regularly cleaning your lawnmower, you can remove any potential hazards and ensure that it is safe to use.

Saves Money

Regular maintenance and cleaning of your lawnmower can save you money in the long run. By keeping it clean and in good condition, you can reduce the likelihood of expensive repairs or having to replace the mower altogether. Additionally, a well-maintained lawnmower uses less fuel and is more energy-efficient, saving you money on operating costs.

10 Methods How to Clean a Lawnmower

1. Empty the Gas Tank

The first step in cleaning a lawnmower is to empty the gas tank. This should be done before any other cleaning tasks are performed, as gasoline is highly flammable and can be dangerous if not handled properly.

To safely empty the gas tank, turn off the engine and allow it to cool before carefully draining the fuel into an approved container. Once all of the fuel has been drained, dispose of it in accordance with local regulations.

2. Clean the Spark Plug

The next step in cleaning a lawnmower is to clean the spark plug. This should be done periodically to ensure that your mower runs smoothly and efficiently. To clean the spark plug, remove it from the engine and use a wire brush or sandpaper to remove any dirt or debris that may have accumulated on its surface. Once it is clean, re-install it back into the engine and reconnect any wires that may have become disconnected during removal.

3. Clean Out Debris from Underneath

Once you have emptied the gas tank and cleaned the spark plug, you can begin to clean out debris that has collected underneath your mower’s deck. This should be done regularly to prevent clogs or other issues that could affect your mower’s performance. To do this, turn your mower over onto its side so you can access underneath its deck more easily. Then, use a putty knife or similar tool to scrape away any dirt or debris that has built up over time.

4. Replace A,r Filter

Replacing your lawnmower’s air filter is another important part of keeping it running smoothly and efficiently for years to come. The air filter helps keep dust and other particles out of your engine, which can cause damage over time if left unchecked. To replace an air filter, simply locate it under your mower’s hood and unscrew it from its housing before inserting a new one in its place.

5 . Sharpen Blades

Sharpening your lawnmower blades is essential for achieving a smooth cut when mowing your lawn each week. Over time, blades will become dull due to wear and tear from regular use, so they need to be sharpened periodically in order to maintain their effectiveness. You can either sharpen them yourself using a file or take them into a professional shop where they will sharpen them for you quickly and easily with specialized tools designed for this purpose. 

6 . Clean Exterior Parts

The exterior parts of a lawnmower should also be cleaned regularly in order to keep them looking their best while also preventing rust or corrosion from forming on metal components like screws or nuts over time. To do this, simply use warm water mixed with mild soap or detergent along with a soft cloth or brush. Be sure to pay special attention to areas like handles, wheels, control levers, etc . which are prone to collecting dirt more easily than other parts. 

7 . Lubricate Moving Parts

In addition to cleaning, it’s important to lubricate all moving parts on your lawnmower periodically as well. This will help reduce friction between these parts, helping them move more freely while also reducing wear and tear over time. Most types of lubricants are suitable for this task, but make sure you read labels carefully when selecting one so you know what type of lubricant is best suited for each specific part of your mower. 

Important to Lubricate All Moving Parts

8. Check Tire Pressure

Another important maintenance task when cleaning a lawnmower is checking tire pressure. Low tire pressure can cause poor handling as well as decreased fuel efficiency, so make sure you check each tire’s pressure at least once per month using an appropriate gauge ( available at most auto supply stores). If necessary, add air as needed until each tire reaches its recommended pressure level according to manufacturer specifications found in your owner’s manual. 

9. Inspect Belts & Hoses 

Belts & hoses should also be inspected periodically when cleaning a lawnmower since these components are responsible for transferring power from one part of the machine to another (i.e., transmission belt ) as well as providing fluid flow (i.e, oil hose ). Look for signs of cracking , fraying , leaks , etc., which may indicate worn-out belts & hoses that need replacing sooner rather than later in order to avoid costly repairs down the road due to component failure during operation. 

10. Test Run After Cleaning 

Finally, once all maintenance tasks have been completed after cleaning your lawnmower thoroughly, don’t forget about testing it out afterward! Start up your mower and let it run for a few minutes to ensure everything is running smoothly and no issues arise while it is in use.

This will give you peace of mind knowing that your lawnmower has been properly cleaned and maintained, allowing you to enjoy a beautifully manicured lawn without any worries or hassle.

Things to Consider When Cleaning a Lawnmower

Cleaning a lawnmower is an essential aspect of lawn maintenance and should be done regularly to keep it running smoothly. A clean mower will also ensure your lawn looks neat and healthy.

Safety First

Before you begin cleaning your lawnmower, it’s crucial to prioritize safety. Make sure the lawnmower is turned off and disconnected from any power source before starting the cleaning process. This will prevent any accidents or injuries while handling sharp blades and other moving parts.

Gather Necessary Tools

Cleaning a lawnmower can be a messy job, so it’s essential to gather all the necessary tools beforehand. Some of the tools you may need include a scraper, stiff brush, rags, and a bucket of soapy water. Having everything ready will make the process more efficient and prevent any delays.

Remove Debris

The first step in cleaning a lawnmower is to remove any debris or grass clippings from the deck and blades. Use a scraper or stiff brush to loosen and remove any caked-on debris. This will prevent buildup and ensure your lawnmower is operating at its best.


In conclusion, knowing how to clean a lawnmower is an important part of maintaining its performance and longevity. Without proper maintenance, a mower can become damaged beyond repair due to corrosion or improper lubrication.

Taking the time to learn the process of cleaning your mower will save you money and headaches in the future and make sure your machine functions as it should. Make sure you take all the necessary steps for proper cleaning like draining gasoline, clearing debris, removing rust build-up, lubricating blades and oiling engines.
