Before cleaning, please make sure you have unplugged your toaster and let it cool down. The crumb tray on the base of the toaster can then be removed and wiped with a clean damp cloth and dried before placing back into the toaster. This should be done regularly to prolong the life of the toaster.
If you want to clean the outside of the toaster, wipe the outside of the toaster with a damp cloth, and then dry immediate. Please ensure the toaster is dry before plugging in the toaster.
