What if we told you there was a way to clean your spark plugs without taking them out? Yes, you heard it correctly – in this article, we will guide you through some simple yet effective methods on how to clean spark plugs without removing them! Save time and money with our tips and tricks – let’s get started now!

What are Spark Plugs?

Most people think of spark plugs as small, cylindrical devices located in the engine that help ignite the air/fuel mixture, but in reality they’re quite versatile. Spark plugs can be used to measure pressure or temperature, for example.

Spark plugs come in a variety of shapes and sizes, and different brands use different types of electrodes. The most common type is a round electrode housed inside a hexagon-shaped casing. When the plug fires, it sparks and sends electrical current through the electrode and into the engine.

If you need to clean your spark plugs but don’t want to damage them, there are a few options available to you. You can use mineral oil or gasoline to heat up the plug and loosen deposits buildup. You can also use a wire brush to remove deposits manually.

How to Clean Spark Plugs

If your car has a spark plug issue, there are a few steps you can take to try and fix the issue. Some of these steps may require removing the spark plugs, some may not. Here are three ways to clean spark plugs without removing them:

The first way to clean spark plugs is to use a wire brush. This can be done by inserting the wire brush into the plug hole and scrubbing the insulator and metal against the electrode. This method should be used if the fouling is minimal or if you do not want to remove the spark plugs.

The second way to clean spark plugs is with compressed air. Blow into the plug hole until it becomes clear and then remove the plug. Repeat until all plugs are cleaned. Use caution when using compressed air; it can be dangerous if used incorrectly.

The third way to clean spark plugs is with a rubber hose and an adjustable spray nozzle. Connect the hose to the spout on the nozzle and turn it on to full spray. Squeeze one end of the hose so that water pressure builds up in it, then insert the other end into the plug hole. Hold down on the top of the hose while spraying from underneath, then release when water has reached your desired level.


If you’re experiencing hesitation or problems starting your vehicle, it’s probably time to clean the spark plugs. Here’s a guide on how to do it without removing them.

Step One: Park your car in a safe place and turn off the ignition.

Step Two: Remove the air intake grill and unscrew the five screws that hold the cover in place.

Step Three: Carefully pull out the spark plug cables. You may need to use a screwdriver to gently pry them out.

Step Four: The electrode should now be exposed. Wet a cloth with dish soap and wring it out so that it’s foamy. Squeeze some of the dish soap onto the clogged electrode, using a circular motion. If using an Eraser, be sure to hold it tightly against the metal surface of the plug and use light pressure against the eraser as you twist it clockwise (the entire plug must be turned). Continue cleaning until all of the build-up is gone. Repeat for each spark plug.

Put everything back together and reattach cables. Start your car and see if your hesitation or problem has been resolved.
