The toaster oven has a removable tray above the lower heating element to help it catch crumbs. You can remove the tray with the front door closed by pulling on the concealed handle just below the glass, being careful not to spill said crumbs all over the counter. Then wipe down the inside and outside of the glass, put the wire racks and pans through the dishwasher (or handwash them), and you're done!
