Making toast is messier than one might think. I guess the action of popping the toast out of the toaster helps shed a few crumbs. Over time the crumbs can build up.
Toasters can be cleaned by emptying the little crumb tray at the bottom of the toaster. However, not all the crumbs are kind enough to make their way onto the crumb tray. Some like to stay stuck to the bottom of the toaster. Turning the toaster upside down and giving it a good shake will dislodge a few more of these crumbs, however, the really stubborn ones hang on for dear life. What to do? It is a narrow space and a long tool is required.
First off, unplug the toaster. Next, wrap a paper towel around a pencil or kabob stick and secure with a rubber band. Now this little cleaning tool can be used to reach down to the bottom of the toaster and dislodge those stubborn crumbs who could not be shook out.
The outside of the toaster can be shinned up as well with a little white vinegar. For the metal parts, use a little cream of tartar and water made into a paste and use a non-abrasive scrubber to buff out any residue. Voila! The toaster is as good as new!
