Step 1: Unplug and Scrape Inside the Slots
0:55
Before you touch anything, unplug the toaster. Then grab an old toothbrush and use the pointed tip to scrape along the inside walls of each slot. You're loosening the built-up crumbs and carbon that sticks to the inner walls. Go down each slot - there are usually four. You won't get everything, but this knocks off the worst of the buildup and makes the next steps more effective.
