1. A toaster should not bake a buttered piece of bread to prevent the butter from melting and sticking to the oven cavity.
2. Toasters should bake fresh bread or bread with a certain humidity, otherwise easy to burn.
3. Do not slice freshly baked bread or bread that has a high temperature immediately and put it into the oven to bake. Otherwise, the bread will be too soft to jump up and block the exit.
4. The toaster should be cleaned after each use until the oven is cooled to normal temperature. If the surface of the shell is too dirty, semi-dry wet cloth can be dipped in some detergent wipe, and then dry with a soft cloth.
