Can You Clean Spark Plugs Without Removing Them?

As you already know, the spark plugs are engineered to ignite the air/fuel mixture, which is necessary for the engine to produce power. During the working process of the spark plugs, they often get exposed to fuel contaminants, dirt, carbon deposits, and debris. Over time, the accumulation of dirt, debris, and carbon deposits on the spark plugs make them fail to operate correctly.  

Once your spark plugs start ceasing to operate properly, the best thing to do is to clean the devices and eliminate any dirt and debris around them. 

It’s not ideal to just clean the spark plug, especially if it’s been a long time since you last cleaned the device. Over time, the plugs would have come in contact with carbon deposits, oil, and ash formation. All of these could affect the performance of the spark plugs, as well as that of the engine.

To achieve the best results, it’s not a good thing to just clean the spark plugs. Instead, you need to first remove the plugs and clean them. In addition to that, you also need to clean the spark plug holes before reinstalling the spark plugs.

That said, here are a few steps that you can follow to clean your spark plugs the right way:

  • The first thing you need is to remove the spark plugs. To do that, start by disconnecting the negative terminal on the engine’s battery.
  • After that, locate the plugs and apply a can of compressed air to remove debris around them.
  • Next, disconnect the spark plugs wire one at a time. After that, unscrew the plugs and start cleaning them.
  • Use sandpaper to clean and remove the grime on the electrodes. Furthermore, use a wire brush to scrub the threads of the spark plugs and eliminate any build-up of oil.
  • Next, spray down the spark plugs using the appropriate brake cleaner. Also, consider cleaning the spark plug holes before reinstalling the plugs and performing the appropriate setup.

Apart from using brake cleaner, you can also consider using a blow torch to clean the spark plugs.

  • To do that, you need to first grip the spark plug with a plier. The purpose of that is to avoid hurting your finger when the torch starts getting hot. Alternatively, in the absence of a plier, you can n consider using a bench vice.
  • Next, you need to put on the blow torch. However, before doing that, you need to put on gloves. This way, you can always protect your hand from heat.
  • Now, place the spark plug end directly in the flame. The flame will help you burn the debris and carbon deposit around the plugs.
  • Since the spark plugs are already hot, you need to wait for some time before considering installing them back.
  • Before installing the spark plugs, you need to set the gap between the electrode and the plug. The best way to do that is by using a gap tool. Also, check your vehicle’s manual to see the exact gap measurement for the spark plugs.
  • Lastly, after setting the gaps, reinstall the spark plugs into the hole, making sure they are properly seated.

The bottom line is that it’s not ideal to just clean the spark plugs. The best way to go about it is to remove and clean the spark plugs. After that, consider cleaning the holes before reinstalling the spark plugs.

Thankfully, I have a father-in-law who's obsessed with cars and a brother getting a PhD in internal combustion engines, so I get to learn about fixing cars. And with Fixing Engines, I hope to help you save a lot of money and take good care of your cars.
