The flat top grill, a favorite among restaurants and passionate home cooks, is a simple and effective piece of cooking equipment that can be maintained easily to last you a long time. They’re different from conventional grills and griddles because of their flat stainless steel (or chromium) surface that you can cook directly on top of. You can also cook anywhere on the surface and get relatively even results, unlike a traditional griddle or stovetop. This cooking surface is where the food will be, so it will obviously need the most regular cleaning.

Other important parts to keep clean would be the gutter where all the food debris and grease goes, and the heating element underneath the cooking surface. There are no grates for dripping fat or marinade like on other grills.
