When you notice that the spark plug is dirty, there is a way to clean the lawn mower spark plug that you can try. Do you know how to do it? The lawn mower is essential to keep the grass neat and well-maintained. However, lawn mowers require proper maintenance, including the spark plug, like any other machine.

Dirty or rusty spark plugs can cause problems with the engine's performance and even damage it. In this article, Honda Power will provide complete information on how to clean lawn mower spark plug. Make sure you read it until the end.

Why Should You Clean the Lawn Mower Spark Plug?

Cleaning the lawn mower spark plug is very important to maintain the performance and extend the engine's life. It is because the spark plug serves as an electrical conductor that ignites the gasoline. If the spark plug is dirty, the engine will be difficult to start or may not be started at all.

In addition, a dirty spark plug can also cause higher fuel consumption and emissions, as well as faster engine damage. On the other hand, regularly cleaning the lawn mower spark plug can help improve engine efficiency and reduce emissions that can damage the environment.

The process of cleaning the lawn mower spark plug is basically very simple. You can use a spark plug brush or a regular brush that is easy to find. Not only that, you can also use a special spark plug cleaner, which is good because it can help keep the spark plug in good condition. After cleaning the spark plug, make sure to check its condition. 

If it still cannot be used, you need to replace the spark plug because it is most likely damaged. Cleaning the lawn mower spark plug can also be done as part of routine maintenance of other machines, including checking and replacing lubricating oil, checking and replacing air filters, and cleaning gasoline filters.

How to Clean Lawn Mower Spark Plug 

Not only ensure the cutter, which is the grass-cutting part, is clean after use, but you also need to pay attention to the cleanliness of the components inside the engine. To avoid causing further damage to the engine, you should follow the steps below to clean the spark plug of the lawn mower.

1. Turn Off the Lawn Mower First

The first step in cleaning the spark plug of a lawn mower is to turn off the engine. You cannot clean the spark plug if the engine is still running as it can endanger your safety and security. 

Therefore, turning off the lawn mower is a critical step to take, especially since you need to remove the spark plug to clean it. It would be best if you did this when the engine is cool and no electric voltage is connected.

2. Remove the Spark Plug

To remove the spark plug, you need to open the spark plug compartment by removing the spark plug cable from the spark plug terminal. The spark plug compartment is usually located on top of the engine and is protected by an easily removable cover. Once you have removed the cover, simply remove the spark plug to clean it.

3. Clean the Spark Plug with a Fine Wire Brush

Clean the spark plug using a spark plug wire brush or a soft brush to help remove dust, dirt, and residue attached to the spark plug. Then clean the area around the spark plug by removing dirt that is attached to each side of the spark plug. This will help remove any dust and dirt that may be attached around the spark plug and cause engine performance problems.

Open the spark plug cable and clean the inside of the cable with a soft brush. Spark plug cables that are dirty due to dust or rust can cause problems with engine performance.

4. Reinstall the Spark Plug

If you feel the entire spark plug is already clean, reinstall the cable to the terminal and cover the spark plug compartment. Ensure the cable and spark plug terminal are clean and dry before closing the compartment.

Installing the spark plug after cleaning it should be done in a dry condition because moist air can cause unstable electric currents and cause problems with engine performance. If the spark plug is wet, the electric current flowing to the spark plug will not be optimal because evaporation can trigger short circuits and damage the spark plug.

It can also cause inefficient fuel consumption of the lawn mower engine and the engine cannot work optimally. Furthermore, a wet spark plug can accelerate the corrosion process on the terminal and spark plug cable. This corrosion can cause new problems with electrical connections and, of course, affect how the engine works.

5. Try Starting the Lawn Mower

After everything is perfectly installed, don't immediately leave the engine. You need to check whether the engine can start properly or not. If the spark plug is malfunctioning, check the cable and terminal immediately to ensure their condition.

Dear Honda Power friend, paying attention to the maintenance of every component of the lawn mower engine is important. Because it greatly affects the performance and lifespan of the machine. 

Therefore, remember to regularly check and clean the spark plug, as a dirty spark plug can cause the lawn mower to malfunction. Also, use a soft brush to clean the spark plug, as rough brushes like wire or sandpaper can damage it.
