How To Clean Rusty Cast Iron Flat Top Grill
To clean a rusty cast iron flat top grill, start by turning off the gas and allowing the grill to cool completely.

Removal of Rust: Use a steel wool pad to scrub off rust
Rust is an insidious enemy of cast iron flat top grills, and it can quickly degenerate the beautiful aesthetic of a grill. Fortunately, there are a few easy steps you can take to effectively remove rust from your cast iron flat top grill.
The first step is to use a steel wool pad to scrub away the rust. Steel wool is an ideal tool for this job, as it’s both abrasive and gentle enough to not damage the underlying metal. Start by lightly scrubbing the affected area, and then gradually increase the pressure you’re applying as needed. Make sure to scrub in circular motions to ensure the rust is removed evenly. Steel wool can be quite effective at removing rust, but if the rust is particularly stubborn, it may be necessary to use a wire brush.
Once you’ve finished scrubbing the affected area, it’s time to move on to the next step. This involves using a chemical rust remover to help dissolve the rust. There are a variety of chemical rust removers available on the market, so make sure to read the instructions carefully before using. Generally, you’ll want to apply the chemical rust remover to a soft cloth and then use it to rub the affected area. Make sure to wear gloves and safety glasses when using chemical rust removers.
After the rust has been removed, it’s important to clean and season the cast iron top grill. Cleaning the grill with a mild detergent and warm water will help to remove any residue from the chemical rust remover. Once the grill is clean, you’ll want to season it with cooking oil. This will help to protect the grill from rust in the future.
Removing rust from a cast iron flat top grill can be a time-consuming process, but with the right tools and a bit of patience, you’ll be able to restore your grill to its former glory. Steel wool and chemical rust removers are the keys to success, so make sure to have these items on hand before you begin the process. With a bit of elbow grease, you’ll be able to restore your cast iron flat top grill and enjoy it for many years to come.
