To get rid of the moisture, simply spray WD40 on them. The coating on ignition systems and other electrical components may be prevented by using WD40. It cleans the spark plugs of dust and debris.

To maintain your spark plugs clean, we’re going to focus on the usage of WD40 in this blog.

Basic Background: Types of Spark Plugs

Spark plugs are currently primarily divided into two categories: basic nickel and advanced iridium.

An electrolyte alloy of nickel with other metals, such as steel, can be used as a side electrode on nickel-based ones. Cylinder-shaped electrodes are used instead of precious metals.

In addition to the center electrode, iridium electrodes also have side electrodes. Even though the base is constructed of common metals, iridium, platinum, and other precious metals are sprayed on top in extremely fine particles. 

These steps protect the sharpened needle-like center portion from burning at high temperatures.

Other Proven Methods to Clean Spark Plugs

Mechanics and do-it-yourselfers of all skill levels may easily clean spark plugs. Spark sparks can be cleaned in a variety of ways.

You must first remove the spark plugs before cleaning them; there is no such thing as cleaning them without taking them out first. Before deciding which approach to utilize, you must remove the plugs from the sockets to have access to them.

Pulling the Plugs to Remove the Spark Plugs

Trace the ignition coil or the spark plug wire to find the spark plugs. As a last resort, consult your owner’s handbook if you cannot determine where the spark plugs are in your car.

Compressed air works best for removing dirt and debris. Wear safety goggles while using pressurized or bottled air to remove the trash. One by one, disconnect the plug wires.

Reinstalling the plug wires will not be a problem if you remove them all at once. Make sure to hold it in place on the low boot and gradually take it out. Hold the cable firmly and twist it a little to release it if it’s adamant about coming out.

Connect a ratchet handle and an extension to a spark plug socket. To remove the spark plug, insert a plug socket into the hole and spin it counterclockwise.

Method 1: Abrasive Cleaning

Use 220-grit sandpaper to clean the electrodes: 

To the end of every spark plug is a small pole (the part that goes into the engine). An electrode is what you’d call it.

If it’s discolored or covered with carbon deposits, take some sandpaper and gently sand the area until no more carbon remains. The electrode should be sanded until it is as bare metal as possible.

Sandpaper should remove the carbon deposits, but if it doesn’t work, try filling them off with a file. You may do this by squeezing the file between the plug body and electrode.

Wire brushes the plug threads to remove any filth or grease present. It’s a sign that oil is present in the spark plug holes if oil is present on the rotors.

Dura-Gold Premium 220 Grit Sandpaper can be a wise option for this method.

Use Carb cleaner: 

Inexperienced mechanics may question how to use a car cleaner to remove carbon deposits from spark plugs. So what is Carb cleaners? You can successfully remove carbon deposits and other dirt from various engine components by using carb cleaners.

Wipe the surface clean with a fresh towel after using the Cleaner. Additionally, it swiftly dries and leaves you with clean spark plugs.

Use a wire brush and carb cleaning if the carbon deposits are very obstinate. To remove any remaining carb cleaner from the plug, use a clean cloth or rag to wipe it off completely. All of the spark plugs should be replaced simultaneously.

You can use the Gumout 800002231 Carb and Choke Cleaner for maximum outcome.

Method 2: Using Blow Torch

A blow torch will heat the spark plugs up. To avoid burning your hand, you must expand the plugs using a plier.

Pull the plugs at the ignition coil end. Hold it firmly but do not pressure it to avoid damaging the plug. The plier is just an extension. Pliers are better than a bench vice.

Turn on your propane touch or gas, light the nozzle or press the ignition button. To light and maintain the fire, turn the torch up until blue flames appear.

The touch will clean the spark plugs of any dirt and oil. Fear not; the plugs will withstand the heat without difficulty. Rotate the spark plug while burning it until the electrode and the end blaze red.

Final Verdict

Congratulations, you’ve just cleaned a spark plug! The spark plugs may need to be cleaned if your machine won’t start or if it’s functioning less effectively.

Plugs should be checked often for engine buildup, potentially every time you replace the oil in your vehicle.

FAQ’s

What Is Spark Plugs?

In a spark-ignition engine, a spark plug is a component that delivers electric current from an ignition system to the combustion chamber in order to ignite the compressed fuel/air combination by an electric spark while keeping combustion pressure within the engine within safe limits.

How do the Spark plugs need to be lubricated?

Applying grease to a spark plug is essential, but it’s also important to consider how and where you apply it. It would help if you only used dielectric grease on the spark plugs since it acts as an insulator.

How frequently should the spark plug on a small motor be changed?

A well-maintained spark plug can endure for many years. The spark plug in my lawnmower hasn’t needed to be changed in a while, but I do clean it as described in this post.

How much does it cost to replace spark plugs in a vehicle?

According to the type of plugs you require and the number of cylinders in your engine, you may expect to pay anywhere from $16 and $100 for a set of spark plugs.
