They should be okay, if there is a lot of buildup I prefer to use Marvel's mystery oil and let it soak for a bit, then come few hours later. It works to loosen up the buildup, but I think you should be okay with out it. Remember always start the spark plug by hand (using extension) that way you will not strip the threads.
