If it’s black and sooty, it’s time for a new one. If it’s white or light-colored, it may just need to be cleaned. To clean a spark plug, use a wire brush to remove any built-up deposits.

If the spark plug is still dirty, you can use a spark plug cleaner to remove any stubborn deposits. Once the spark plug is clean, it’s time to install the new one. Simply screw it in by hand until it’s snug, then use the spark plug wrench to give it a quarter turn.
