Spark plugs are like tiny lightning bolts! But don't focus on their size; they are vital in starting the car or a generator diesel generator manufacturer. They are responsible for generating the electrical spark that creates the ignition needed to start the engine. Another cool feature of spark plugs is that they clean themselves. You might be wondering how? Well, the heat generated by the engine can cause the spark plugs to burn everything.
So how can the spark plug be fouled? During the rainy season or when the car is being serviced, the accumulation of moisture in the spark plug will cause the car to fail to start. Also, if your vehicle is idling, dust and grime can build up on the spark plugs. In addition, over time, a carbon residue builds up on the surface of the spark plug. All of the above factors can lead to a decrease in spark plug efficiency. It will directly affect engine performance and fuel mileage. Now, no one wants that.
So, we will teach you how to clean your spark plugs and take some precautions to keep these little guys running smoothly.

How to clean a spark plug
Step 1: Locate and remove the spark plug
As a general rule of thumb, ensure the engine is completely cool.
First, remove the engine cover. The spark plug is located in the combustion chamber cylinder below the ignition coil. To access them, use a wrench to unbolt the combustion chamber. Before doing so, brush away loose dirt and debris that could fall into the spark plug hole or combustion chamber. Remove the ignition coil from the cylinder. Insert the socket wrench consisting of the extension rod and spark plug socket to loosen the spark plug. Then carefully pull out the spark plug with pliers.
Step 2: Interpretation of spark plugs
Before you start cleaning your spark plugs, have them analyzed. Spark plugs tell the story of your engine. So check them out and discover what's happening inside your car's or generator’s engine. Below is a brief overview of spark plug conditions and what they mean.
● If the spark plug's center electrode is worn, it needs to be replaced.
● A dry, smoky appearance to the spark plug's center electrode may indicate a fuel leak. You'll need to check the spark plugs on all cylinders to verify; if there is a leak or an overall fuel control issue.
● If you notice a slight discoloration in the spark plug's center electrode, but no deposits, this is normal. This indicates that the spark plugs are functioning and the engine is working perfectly.
● If the outer electrode of the spark plug has dry, sandy deposits, then there is a problem. The valve seals are not working, and oil is sucked into the cylinder. You need professional help to solve this problem.
● If you notice a lot of wet, muddy deposits on the ends of your spark plugs, it's a sign that you need to overhaul your engine for major internal repairs.
● After checking your spark plugs, it's time to clean them thoroughly.
Step 3: Cleaning spark plugs with WD-40 MUP
WD-40 is great for cleaning spark plugs. Spray the WD-40 multi-purpose product on a microfiber cloth and wipe the spark plugs. You can even spray WD-40 directly on the spark plugs and wipe them with a clean cloth. After cleaning the spark plugs, put them back and start the engine to see the difference.
Preventive maintenance
WD-40 multi-purpose product not only helps in cleaning spark plugs but also in preventive maintenance. It acts as a lubricant, thereby reducing general wear. WD-40 MUP removes moisture to improve connectivity and enhance its performance. Not only does it help remove rust, but it also prevents it. All in all, it's the best chemistry for spark plugs.
Three methods of cleaning spark plugs
Method 1: Clean with abrasives
Clean the electrodes with 220-grit sandpaper: A small pole will always stick out of the end of the spark plug. It's called an electrode. If there is carbon buildup or discoloration, take sandpaper and rub it lightly until there is no carbon buildup.
Continue sanding the electrode until it looks like bare metal. Wearing goggles is recommended when sanding. Sandpaper is the best spark plug cleaners on the market.
Use a file to remove carbon deposits: Sandpaper should do the trick, but if it doesn't, consider filling in stubborn deposits with a file. Place the file over the gap between the plug body and the electrode and slide it back and forth.
You can clean the threads with a wire brush: There may be oil and dirt on the plug threads. If there is oil on it, it is in the spark plug hole. Also, make sure to clean the spark plug hole before reinstalling the spark plug. Brushing the plug from a vertical angle easily removes deposits and debris from the threads. Then, turn and brush the plug from different angles.
Wear gloves when cleaning the plug with a wire brush so you don't poke yourself. The thread doesn't have to retain its color to work, but you must remove any deposits.
If you're an entry-level mechanic, you're probably wondering how to clean spark plugs with carb cleaner. Carb cleaner effectively cleans carbon deposits, buildup, grime, and debris from various auto parts.
To clean with a carb cleaner, place the spark plug on a clean surface, such as a vise, and spray the cleaner. After spraying the cleaner, make sure to wipe it with a clean towel. In addition to being clean, it dries quickly and leaves you with clean spark plugs.
If the carbon deposits are difficult to clean, you can use a wire brush and a carb cleaner. When you're done, wipe the plug thoroughly with a clean towel or rag to dry any carb cleaner.
Repeat the process for all spark plugs at the same time. First, clean, reinstall, and plug the lead or ignition into that cylinder. If you're wondering how to clean a spark plug with vinegar or how to clean a spark plug with gasoline, the process is similar to a carb cleaner.
You need to use a wire brush to brush off the carbon deposits on the plug and soak the plugin vinegar or gasoline for a few seconds.
Method 2: Using a blow torch
A blow torch can make the spark plugs very hot. Therefore, you need to use pliers to hold the plug to extend the length of the plug to prevent your hands from being burned.
Use pliers to grasp the plug at the connection end of the ignition coil. Hold the plug firmly without squeezing it, which may damage the plug. Pliers are only available as extensions. A bench vise is a better alternative to pliers.
Turn the knob on the propane or gas, place the ignition source in front of the nozzle, or gently press the ignition button. This ignites and keeps burning. Turn the torch on high until it begins to produce a blue flame.
Touching will burn off all the junk, debris, and oil on the spark plugs. Don't be afraid to damage the plugs; they will survive the heat with no problem. Continue burning the spark plug while turning it until the electrodes and the end of the spark plug glow red.
Don't let anything distract you or let the torch burn anything else. The burning process may take a few minutes, depending on your torch and its temperature.
Allow the spark plugs to cool down before holding them with your fingers. Plugs need to cool down before use. Care must be taken when handling spark plugs and blow torches; they will revert to standard color before they get cold. To avoid burning your hands, allow each plug to sit for 5 minutes before attempting to reinstall.
Method 3: Use a spark plug cleaning tool
Another proven method of cleaning spark plugs is to use a spark plug cleaning machine. The cleaning tool is designed to supply air and blast the spark plugs. This tool is very convenient.
To use this tool, secure the airbag, tighten the clip, and insert the air source. Press the button on the machine, plug in the spark plug, and switch the mechanism to sandblast. Shake the plug constantly so the cleaning tool blows off any carbon buildup. When you're done blasting, switch the machine to air and blow off debris from the plugs.
We still recommend blowing the spark plugs with an air source. You don't want debris falling into the cylinder.
Cleaning vs. replacing spark plugs
Before replacing the spark plugs, we recommend cleaning them. It's hard to tell if it needs to be replaced unless you've cleaned it and tried it again in your power tool or vehicle.
However, if you notice any damage, it's time to purchase new spark plugs.
Damage includes:
● Heavy carbon deposits that cannot be removed.
● Cracks or breaks.
● The electrodes on the top of the plug are burnt, blackened, green, or damaged.
● If the spark plugs have been used for longer than the maximum recommended time, we strongly recommend that you replace the spark plugs. Clean the existing ones if it takes days or weeks to get new spark plugs. At the same time, it may help the vehicle run better.
For those looking for new spark plugs, you can find them at your local auto retailer or hardware store. For example, you can purchase spark plugs at home depot or Amazon. Before purchasing, always check what spark plugs you need for your power tool or vehicle.
Spark plugs can be expected to cost between $5 and $15, so they are relatively inexpensive. There are many types of spark plugs, such as copper, iridium, platinum, double platinum, etc.
FAQs
1) Can you clean spark plugs and reuse them?
Technically, yes, you can clean the spark plugs, but it's not usually worth it. We don't recommend it for several reasons. Ultimately, a cleaned plug will not perform as well as a new plug.
2) What material is best for cleaning spark plugs?
Carbon, oil residue, and fuel can foul spark plugs, preventing a spark from connecting between the electrodes. Abrasives such as sandpaper, Brillo pads, or wire brushes can help remove any buildup on the center and side electrodes.
3) Can spark plugs be cleaned with gasoline?
If you have the extra budget, you can purchase an electric wire brush to clean your spark plugs faster and more effectively. Some people spray WD-40 or gasoline on the debris on the spark plugs to loosen them.
4) Will cleaning spark plugs improve performance?
There are many benefits to cleaning your car's spark plugs, and you'll be driving better and feeling better in no time. Not only does it improve the car's performance, but it also extends the engine's life - it's what we call a win-win.
5) Can spark plugs be cleaned with kerosene?
Dip the plug in gasoline or kerosene and wipe it clean with a dry, soil-free cloth.
6) What can impair the performance of spark plugs?
The leading cause of spark plug problems is oil flowing into the combustion chamber. Keep in mind, if oil leaks into the combustion chamber, it can cause the tips of the spark plugs to become oily and dirty, causing premature failure.
7) How to lubricate spark plugs?
It is essential not to apply grease to the spark plugs but to know how and where to apply it. Since dielectric grease is an insulator, you'll need to apply a small amount to the spark plugs individually. Don't let it touch the metal connector on the boot. Pick up the oil with cotton wool and apply a small amount.
Apply a thin coat of electrical grease to the inside of the boot using a circular motion. For best protection, you can apply a layer of grease to the ceramic coating of your spark plugs. Use it again in the same circular motion. Make sure not to touch the grease on the metal terminals of the spark plug.
