Can Spark Plugs Still Be Used After Cleaning?

[DelVivian]

Spark plugs can still be used after cleaning. The cleaning methods are as follows: 1. Place the spark plug in a glass container, pour white vinegar until it covers the spark plug, soak for 2 to 3 hours, then scrub clean with a hard toothbrush and let it air dry naturally; 2. Place the spark plug head-down in a glass bottle, spray carburetor cleaner into the bottle until it covers the spark plug, cover the bottle, wait for about half an hour, then take it out, scrub clean with a toothbrush, and let it dry or use a hair dryer to dry it; 3. Soak the spark plug's ignition electrode directly in pure toilet cleaner, place it in a ventilated environment for 10 minutes, wait until the bubbles gradually decrease, then take it out, rinse it clean with white vinegar, and let it air dry.
