What to Use to Clean Spark Plugs?
2 Answers
Using carburetor cleaner to clean spark plugs is recommended. Carburetor cleaner is specifically designed for 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 erosion of spark plugs, such as scarring, damage, or melting and erosion of the electrodes, indicates that the spark plugs are already damaged and should be replaced. Spark Plug Location: Spark plugs are installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. However, over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plugs. Spark Plug Replacement Interval: Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to follow the instructions in the user manual. Generally, 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.
Cleaning spark plugs, as a DIY-loving car owner, I often use specialized engine cleaning spray for the job. First, carefully remove the spark plugs, being extra cautious not to damage the electrodes. Then, spray the cleaner evenly and let it sit for a few minutes to dissolve carbon deposits. Use a soft-bristle brush to gently scrub off stubborn grime. I usually let them air dry for a full day to ensure complete dryness before reinstallation. This method effectively restores spark plug ignition performance, reduces engine vibration, and improves fuel efficiency. Remember: Never use water or metal brushes as they can damage the surface. It's advisable to photograph their original positions before cleaning to avoid incorrect reinstallation. Regular cleaning (once a year is sufficient) can significantly extend spark plug lifespan.
