Query: Portable restaurant flat iron griddle

Very nice stainless flat top grill for outdoors. We use when RV'ing and cook outside the travel trailer, on our two burner camp chef portable stove.Probably works better on a gas grille, as another reviewer mentioned, with the longer tube or bow tie burner shape. We too discovered the heat is concentrated in the center of our portable stove matching the burner shape. If using on a camp stove, be sure to get a heat diffuser (plate with small holes) to diffuse the heat more evenly under the griddle.Make sure when cleaning that you DON'T EVER use a steel wool (brillo style) pad on stainless steel. It leaves little pieces of regular carbon steel behind that will penetrate small surface crevices and rust. Scotchbrite pads work well on cleaning. I find that while still hot, squirt it with a water spray bottle and get things sizzinling and scrape, wipe repeat a couple of times to clean up.
