Keeping your commercial toaster clean is essential for the overall safety and performance of the appliance. Before you clean the toaster, you should always switch it off at the wall, unplug it, and ensure it is cool. The outside can be wiped down daily with a wipe or cloth; a small brush can be useful to get into those tough-to-reach spaces. Most commercial toasters will have a crumb tray, which can be removed, wiped, and cleaned easily. It is important never to turn the toaster upside down or to shake them to remove crumbs, as this can loosen internal components and lodge the crumbs inside further.
