How often should spark plugs be cleaned?

[SanPaige]

Spark plugs should be cleaned every 10,000 kilometers and replaced after driving 40,000 to 60,000 kilometers under normal maintenance conditions. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Damaged spark plugs can cause the following issues: If spark plugs are damaged, they can directly lead to leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and other problems. The most significant issue is difficulty in ignition, affecting the normal operation of the vehicle. Severe erosion of spark plugs, such as scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plugs are damaged and should be replaced.

I usually drive to and from work, so small components like spark plugs really need extra attention. Generally, I recommend checking them every 20,000 to 30,000 kilometers, and cleaning them as needed. If you frequently drive short distances in the city like I do, carbon deposits can build up easily, so the cleaning frequency should be higher—about once a year. If you mostly drive long distances with less carbon buildup, you can stretch it to three years. The cleaning method is simple—I’ve tried spraying them with a dedicated cleaner and wiping them dry. But if you notice engine shaking or a sudden spike in fuel consumption, take it to a repair shop immediately—don’t wait for bigger issues to arise. Regular maintenance can extend the lifespan of spark plugs, saving fuel and ensuring safety.

When it comes to spark plug maintenance, from a servicing perspective, cleaning isn't a routine task but more about checking for issues. I usually take a look every 20,000 kilometers or so to check for carbon buildup or oxidation signs. Cleaning frequency depends on driving habits: if you frequently drive in congested areas or use low-quality gasoline, spark plugs get dirty faster and may need cleaning every six months to a year. You can DIY by gently brushing with an alcohol-dipped toothbrush, but be careful not to damage the electrodes. The impact is significant - heavy carbon deposits lead to unstable ignition, reduced engine power, and increased fuel consumption. New car spark plugs are of better quality, allowing longer cleaning intervals, but don't ignore the manual's recommendations. Addressing minor issues promptly can prevent major repair headaches.

The frequency of spark plug cleaning isn't a fixed number, it depends on actual conditions. My simple suggestion: For daily driving, inspect every 20,000 km - clean if carbon buildup is found. The cleaning method is straightforward: spray with decarbonizer a few times and let dry. Replace if spark plugs show severe aging. Owners with frequent short trips or cold starts should clean more often. Regular cleaning maintains ignition efficiency, saving fuel and boosting power. Don't delay too long to avoid triggering the engine warning light.
