Care

Small ovens are much easier to clean than built-in ovens, which is an advantage.
Most models have a non-stick coating on the inside, while the body is either enamelled or made of stainless steel, so it just needs to be wiped clean.
The steel shelves and trays are safe to be washed in a dishwasher.
Most have a removable tray, where crumbs and other food debris accumulate.
