    What About Rust On Cast Iron

    Aside from burning meals by using the wrong temperature, novice cooks are intimidated by maintaining cast iron. It’s far easier than it seems, but if it starts to rust, as it did in this case, most people wouldn’t be bothered to repair the damage. It’s just $30 for a new pan or grill, after all.

    But my dad was a TV repairman in the 1970s, and I come from a long line of poor hillbillies who fix things. To me, rusted cast iron screams “WEEKEND PROJECT.” I did something similar about three years ago, when I also found a Lodge 9-inch cast iron skillet on the curb. People really just don’t take care of the things they buy, and find it’s easier to just buy new things instead of fixing broken ones. Alas.

    Tips For Cleaning Rusty Grill Grates

    You have several options when it comes to rust removal. Fortunately, most of them can be achieved using simple household ingredients. If you have access to any of the materials listed below, we would recommend using one of these techniques before putting food on a rusty grill.

    Tip: If all else fails, you can place a couple of pieces of aluminum foil on the grate and cook the food on those instead. This technique works better if you fold the edges of the foil around the bars of the grate to anchor it in place. You might also want to poke a few holes in the foil to allow grease to escape, as the buildup could pose a fire hazard.
