Removing Spark Plugs
Did you know that even NASCAR (National Association Stock Car Racing) uses WD-40 to help remove spark plugs? Well, they do! Once again, all you need to do in order to remove stuck spark plugs is spray a little WD-40 and watch the plugs come apart easily.

Cleaning Saws
If you work with a hand saw, round saw, or a mechanical saw, then you know they can get dirty very quickly. As it turns out, WD-40 can help with this issue. Just spray it on the saw as well as the blade and wipe the dust off. You can do the same thing to clean off tar or excess gunk.
