What can be used to clean spark plugs?

[Melinda]

Using carburetor cleaner to clean spark plugs is recommended. Carburetor cleaner is specifically designed for engine oil, grease, and carbon deposits, effectively removing carbon buildup without damaging the spark plugs. If spark plugs are damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in starting, affecting the normal operation of the vehicle. Severe spark plug erosion, including scarring at the top, damage, or melted and eroded electrodes, indicates that the spark plug is already damaged and should be replaced. Spark plug location: Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition wires, but in the past decade or so, most car engines have switched to direct connection between the ignition coil and the spark plug. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to follow the user manual. Generally, platinum spark plugs should be replaced every 40,000 kilometers, ordinary nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
