Hell I just treat mine like I do a gas grill. When I cook on it I let it stand till the next time (which is usually the next night) and then I plug it in, let it get hot and saturate a paper towel. I keep the towel dripping wet and make several passes over the heated surfaces letting the water and gunk drain into the little catch pan. Let it dry and then cook. I haven't had any problems with this method but I'm sure some wouldn't think it sanitary.... but then as Booger said heat disinfects best.
