Stay away, stains
A good quality grill often leaves behind pieces of meat and dirt once it has been used. It can look gross and it’s annoying to clean it and none of that dirt decides to go away until it has completely disappeared.
For this hack to work, you need the grill to be on or continue to emit heat. With a piece of aluminum foil, grease and grime will come off the grill in just a few minutes and in just one cleanup. Did we already mention that aluminum and heat are excellent friends?
