Iridium spark plugs are known for their exceptional durability and long service life. However, over time, they can become covered in dust and debris, which can affect performance and lead to fires. This has left many people wondering if it is possible to clean iridium spark plugs, and if so, how should they be handled?
The good news is that cleaning iridium spark plugs is absolutely fine. In fact, this is often a necessary step to maintain their longevity and performance. However, care must be taken when cleaning to avoid causing damage or affecting its performance.
The first thing to consider is the type of cleaner or solvent you will be using. Avoid using harsh chemicals or solvents that may damage spark plug electrodes or insulators. Instead, choose a mild cleaner such as brake cleaner, carburetor cleaner, or even alcohol.
To clean the spark plug, remove it from the engine and place it on a clean, flat surface. Use a soft-bristled brush or toothbrush to gently scrub away any visible dirt or debris. Be careful not to apply too much pressure as this may damage the electrode. For deep-rooted dirt that is difficult to remove with a brush, use a wire brush. However, be sure to use a soft-bristle wire brush as hard bristles can damage the spark plug.
After cleaning the spark plug, rinse it thoroughly with clean water and allow it to dry completely before reinstalling it. It is important to ensure that no cleaning residue is left behind as this can also cause engine misfire or damage.
