If not, you may need to replace the plug after all. Another way to clean a spark plug is by using compressed air and carburetor cleaner spray (again available at most auto parts stores).

First, remove the deposit-covered spark plug from the engine and then spray carburetor cleaner onto both ends of the plug.
