What is necessary in order to clean a toaster from chametz Pesach?
I know the easiest solution is to sell it with chametz, but we prefer to avoid the minhag of mechirat chametz, if possible. (We have no edible chametz left in the house.) Of course, the toaster will not be in use over Pesach itself.
Are there any options for making my toaster clean from chametz before Pesach, that don't involve selling it or disposing of it?
