Another 'time honoured' way I've used on occasions is to gently tap the end electrode with the handle of a screwdriver or similar, which tends to give more control than pressing it against a hard surface. I've had the same set of Champion N9YC in my Minor Traveller for years now, and it still starts and runs well!
