- This will require you to locate the minus symbol and remove its bolt so you can slide it off, so if you are not confident you can do this, then we recommend either asking an experienced friend to help, or alternatively visiting your local garage.
- Find your spark plugs: After you have done the above step, you can then proceed to locate your spark plugs! This should be pretty simple as they are typically connected to the spark plug wires that have swirling coils.
- However, if you are having some trouble locating your spark plugs, then we once again recommend leaving the job to someone who has experience with cars, as it will not only save you time – but also help to ensure that you stay safe. Nevertheless, once located, you will then be ready to begin cleaning.
- Use compressed air to remove surface debris: With a can of compressed air, we recommend that you take a moment to quickly spray over your spark plugs to shoot out any surface debris and dirt that might be getting in the way of the electrodes.
- While this step is optional, we recommend that you do so, as this will help to get rid of any surface debris.
- Clean your spark plugs with sandpaper: After you have gotten rid of all the surface debris, you can then proceed to give each spark plug a deeper and more thorough clean.
- To do this effectively, we recommend that you clean each spark plug one at a time, and take a piece of sandpaper to the electrode area, in order to get rid of any built-up residue that might be interfering with the spark plug engine.
- Scrub the threads: After you have taken the time to thoroughly clean the electrodes of each spark plug with your sandpaper, you can then move on to clean your spark plug threads.
- This can be a little bit tricky to do with a cloth, which is why we recommend that you opt to clean your spark plugs with a wire brush, as this will ensure that you are able to get inside the threads and get rid of any debris that might be residing there.
- Finish with brake cleaner: Last but certainly not least, all you will then need to do is finish up by spraying your spark plugs with some brake cleaner.
- Besides helping to remove any remaining dirt and debris, many people believe that brake cleaner can also help to provide a protective coat to your spark plugs, which will help to prevent any dirt or debris from interfering with their performance for longer.
