Keeping Toaster Oven Cleaner?

My toaster oven always has crumbs in the bottom of it and crumbs also get in the bottom of the glass door. Not to mention that the glass door always looks stained by brown marks. I put foil on my grill pan, but not on the racks themselves. Please help me keep the racks, bottom, and glass cleaner longer. Thanks.
