Your local Toro service dealer is the best place to get the correct replacement spark plug for your machine. Bring your machine's model and serial number so you're sure to get the right plug. Today's spark plugs come pre-gapped, but it's a good idea to double check this before installation.
To safely clean a spark plug, you should use a wire brush or spray-on plug cleaner specifically designed for this ignition part. You can also use a sturdy knife to scrape off tough deposits. Note: NEVER clean a spark plug with a shot blaster or abrasives.

Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.
