Many people enjoy grilling food outdoors, but the cleanup can be a hassle. Food residue and grease can build up on the grill over time, making it difficult to remove. A grill liner is a thin sheet of material that can be placed on the grill before cooking. It will absorb the grease and food residue, making it much easier to clean up afterwards. Grill liners are available in a variety of sizes to fit most grills, and they can be reused multiple times. In addition, they can help to prevent food from sticking to the grill, making for easier and tastier grilled food. So if you love grilling but hate the cleanup, a grill liner may be just what you need.
