Does Spark Plug Cleaning Work?
Spark plug cleaning is indeed beneficial. However, merely cleaning the spark plugs addresses only a portion of the issue. Carbon deposits accumulate in seven engine parts, necessitating comprehensive cleaning to eradicate the root cause of the problem.

Can Spark Plug Cleaning Still Be Effective?
The effectiveness of spark plug cleaning primarily hinges on several factors, including the spark plug’s operational state, such as the flashover condition, gap, and electrode quality. The quality of the flashover significantly influences its efficacy.
How to Check Spark Plugs
As the engine’s ignition component, spark plugs play a crucial role in igniting the fuel mixture in the cylinder. Since a malfunctioning spark plug can prevent the vehicle from starting, owners should conduct regular inspections. Typically, spark plugs should be replaced every 60,000 to 100,000 kilometers, with interim checks every 10,000 to 20,000 kilometers.
To assess their condition, remove the spark plugs and examine them for blackening, carbon deposits, cracks, abnormal scars, or melted electrodes. Additionally, monitor the vehicle’s performance for signs such as difficulty starting or unusual shaking and hesitation while driving.
Best Practices for Cleaning Spark Plugs
- White Vinegar Cleaning:
Place the spark plug in a glass container and cover it with ordinary white vinegar. Allow it to soak for 2-3 hours, or up to 4-5 hours for stubborn carbon deposits. After soaking, use a hard-bristled toothbrush to remove the deposits. Let the spark plug air dry before reuse, avoiding rinsing with water.
- Carburetor Cleaning Fluid:
Submerge the spark plug head in a glass bottle and spray carburetor cleaning fluid into the bottle. Close the lid and wait approximately 30 minutes. Remove the spark plug from the bottle, brush it with a toothbrush, and either air dry or use a hair dryer to complete the process.
- Blue Toilet Cleaner:
Immerse the spark plug in pure toilet cleaner, igniting the electrode. Observe the bubbles generated by the chemical reaction with the carbon deposits. After approximately 10 minutes, remove the spark plug, rinse it with white vinegar, and air dry without using water.
- Professional Cleaning Service:
Visit a repair facility for professional cleaning services, albeit at a higher cost. This option is convenient but may not always entail cleaning and replacing the spark plug.
Notes:
It is advisable to clean spark plugs every 10,000 kilometers for optimal performance.
