Got a new black & decker 4 slot toaster. When I turn it on it smells. I want to say it is like teflon burning, but I don't know if another thread that was talking about teflon tainted my perception. Took it outdoors and ran it 3 or 4 times. Brought it in and it still smells. I don't not want to cook bread in it. I was a dope and I already had the cardboard box recycled. Any advice?
