Second step, safely clean the spark plug with a soft wire brush or spray-on spark plug cleaner. Check the gap of the spark plug using a spark plug gapping tool to ensure it is at the proper measurement. At this time, you can reinstall your spark plug. If it is still damaged, move on to step three and replace your spark plug with a new one. Lastly, remember to reattach the spark plug wire.
