Do Spark Plugs Need Cleaning?

[KyleLee]

Spark plugs need cleaning: 1. White vinegar cleaning: Place the spark plug in a glass container, pour in white vinegar, soak for a few hours, then scrub with a stiff toothbrush to remove all carbon deposits, and let it air dry naturally; 2. Use carburetor cleaner: Place the spark plug head down in a glass bottle, soak it with carburetor cleaner, wait for about half an hour, then remove it from the bottle, spray with carburetor cleaner while scrubbing with a toothbrush, and let it dry; 3. Use blue toilet cleaner: Soak the spark plug ignition electrode directly in pure toilet cleaner, place it in a ventilated environment for about 10 minutes, remove it when the bubbles gradually decrease, rinse with white vinegar, and let it air dry naturally.
