Grill Maestro

One of the simplest things you can do to prevent rust from attacking your charcoal grill is to remove the ashes and wash down the grill. When you leave the ashes and they get wet, such as rain, it creates lye which is caustic and will eat away at your iron grill and create rust. If you want to take the extra step, get a mixture of two tablespoons of vinegar with a gallon of water and rinse it down.

Then, of course, flip it over or something to get it to dry better (moisture + metal = rust).

Happy grilling!
