Abstract: A sanitizing block for cleaning the blade of a food product slicer is manufactured from an inert material, such as cellulose sponge, which does not crumble nor dull the blade of the slicer when positioned on the carriage and sliced in the normal manner as would be used for a chunk of meat or cheese. The sanitizing block is preferably pre-moistened with a sanitizing solution to aid in the cleaning of the slicer and blade. The sanitizing block is useful as a compliment to the normal cleaning procedures of the slicer which often require disassembly of the slicer and washing of the component parts. The sanitizing block reduces food-born bacteria and minimizes carryover flavors from previously sliced items by removing residue remaining on the blade and slicer.
