A rusty grill can affect the quality of the food you prepare while also contributing to major damage. A proper cleaning technique can remove rust and restore your grill grates.
Identify whether your grates are cast iron or stainless steel — you can use a harsh wire brush to remove rust from cast iron or a softer brush to avoid damaging stainless steel.
If you opt for a commercial rust remover, make sure it's made for use on grills and compatible with the grate material. Follow the instructions on the bottle for safe use.
You may have all the ingredients you need for a DIY rust remover in your home right now. If your rust issue is minimal, you may be able to use dishwashing liquid to get rid of it.
Create a cleaning solution consisting of dish soap and warm water and use a cloth to rub it over the grill grates. Rinse them well to remove residual soap prior to grilling again.
For substantial rust, combine powdered dishwashing detergent with lemon juice, which will form a sticky substance that can be spread over rust spots on grill grates.
Allow it to remain on the grates overnight before wiping it and thoroughly rinsing it under water. For faster results, use baking soda and vinegar to dissolve rust in 30 minutes.
To prevent rust, wipe down your grill grates after every use, deep-clean them every 15 uses or so, and cover your grill with a nylon or vinyl cover when it’s not being used.
