Yes, you can clean a dirty spark plug. Start by removing the plug from the engine and brush off loose debris with a wire brush. For tougher deposits, apply a commercial plug cleaner or soak the electrode end in a small amount of petrol or solvent for a few minutes before brushing again. Rinse with clean petrol, allow to dry, and reattach. Inspect for damage; if the plug is cracked or the electrode is badly worn, it's better to replace it.
