Some motels / cabins provide toasters - the "retro" 2-slice toaster that projects the hot toast into the air when its done (and, perhaps sounds a bell, too, if it still works!) The toaster is clean (meaning, no crumbs.)
Could someone use it? My assumption was it's OK b/c the electrical wires in the toaster are red hot and burn off any possibly traif food and there were are no crumbs or any other food particles in the toaster.
