Because
1. Cleaning the whole grill properly would take what? 20-30 minutes?
2. I really don't think it's necessary to clean it every single time.
I'm with zestery on this one, I don't clean my oven either after each use. Nor do I clean the floor behind me while I walk in the house.
Both 'utensils' are in direct contact with food, but you clean one and not the other.
Probably because you think the heat source cleans it sufficiently to kill any germs.
It's your decision
Personally, I don't particularly want to eat pieces of carbon that have been left on the grill, with the food I next cook on it, even if they are 'sterilised'
That's my decision
