Dark grey soot underneith George Forman electric BBQ grills? - bbq grills

I have a George Foreman electric grill, and for the first time since his arrival on the grill last year, I've noticed dark gray soot underneith two grid! It was difficult to clean, but I managed to clean it. But my question is this normal? I want the business? Because I really on the fence to cook, and I am of food poisoning due to pollution fears remain grids particles underneith top on the grill, where the food is cooking.
