THE GRILLBOT-STAINLESS STEEL BRUSHES
Stainless steel brushes are great for cast iron or expanded steel grills. Cast iron is by far the best outdoor cooking surface because it holds heat better than other kinds of grills. However, these kinds of grills are higher maintenance. The steel brushes are great because the bristles are able to penetrate the tiny pores in the cast iron. This allows for a much better cleaning experience.
