If the toaster has a removable crumb tray, chances are you can wash the tray on the top rack of the dishwasher - but check the manual. If not, up-end the toaster over the rubbish bin to remove crumbs.
To clean a sandwich-maker, lift out the plates if possible and clean them in soapy water. Dry scrupulously. If the plates in your sandwich-maker cannot be removed, you have to be more patient. When foodstuff is completely dry, pick off carefully using your fingernail or a plastic spatula. Then, to wash, use a squeezed-out soapy sponge so that you don't flood the machine with water. If needed, soak the plates by laying them on top of a paper towel that has been lightly wetted with your soapy solution. Rinse with a damp cloth. After every ten washes, take a pastry brush and very thinly coat the plates in vegetable oil to protect the non-stick coating. Never immerse the machine in water.
Treat the exterior of both machines to a thorough wipe with a micro fiber cloth. It's a neat way to bring up shine. As an alternative, a spray-on chrome cleaner does a fine job at taking out greasy fingerprints, which is a toaster's biggest problem.
