These Griddle Blocks allow you to safely remove stubborn residue and caked-on carbon from hot grills with minimal effort. Primarily designed to clean dull stainless steel grills, they can also easily clean flame-scorched pots, pans, and other utensils. These Griddle Blocks come individually wrapped in polyethylene film and are made from glass foam. Given that these blocks are made of abrasive materials, they are not recommended for use on polished, chrome-plated, or shiny stainless steel tables or surfaces.
