To make your grill look brand new, start by turning it on high for 15-20 minutes to burn off baked-on residue. Next, empty the grease trap, soak removable parts in hot, soapy water and degreaser, and polish the exterior with a high-quality stainless steel cleaner or a drop of vegetable oil.
To make an old grill look and cook like new, start by doing a deep clean of the interior and soaking the grates. Restore the exterior shine with a stainless steel polish, and replace worn-out, rusted parts like heat tents and burners.

The Cost of Grill Restoration
The total cost will depend on the size of your grill, the type of materials it's made from, and the extent of the wear and tear. For most homeowners in San Diego, restoring a grill can range anywhere from $100 to $500.
Once you've addressed the exterior rust, you can apply a fresh coat of paint to the outside of the grill. Make sure to use high-heat paint. Do not paint any of the insides of the grill or any surfaces that come in direct contact with flames. Grill paint is for exterior use only.
If your grill's repair costs are 50% or more of the price of a new grill, replacing your grill is often the more economical choice. For example, replacing your grill burners and igniter on a 10-year-old grill might cost close to $300, while a new grill could be purchased for around $400.

Using an onion to clean a grill relies on the onion's natural moisture and acidity to steam and lift grease, stuck-on food, and carbon from hot grates. This method provides several practical, culinary, and cultural benefits:
In a large utility sink or plastic tub, mix regular table salt with distilled white vinegar in a 1:2 ratio. Lay the grates in the mixture and allow them to soak overnight.

To restore a rusty BBQ grill, scrub the grates with a wire brush, scraper, or crumpled aluminum foil. Coat with a mixture of baking soda and vinegar for tougher rust. After wiping away the debris, coat the grates with cooking oil and burn them off to season and protect against future rust.
Rubbing a raw potato on a hot grill deposits a layer of starch onto the metal, creating a natural, non-stick barrier. This prevents delicate foods like fish, chicken, or vegetables from sticking to the grates and helps clean away leftover food residue.
If you have an extremely dirty grill with stubborn, caked-on grease or grime that doesn't loosen right away soaking the grimy grates overnight in baking soda and white vinegar can save the labor of scrubbing.
Dawn does not chemically dissolve rust on its own, but it is an excellent tool for loosening and scrubbing away surface-level rust. Because Dawn breaks down grease and grime, it allows water and scouring pads to penetrate and lift rust off metal surfaces like griddles, tools, and hardware.

The best way to clean a grill involves heating it up to burn off debris, followed by scrubbing with a non-wire tool, such as a stainless steel coil brush, pumice stone, or a halved onion for a natural, effective scrub that avoids wire bristle risks. For a deeper clean, a mix of baking soda and soap or a citrus-based cleaner works best.
Hibachi chefs primarily use water or ice, a heavy-duty metal scraper, and a grill brick to clean their flat-top grills. Instead of using harsh chemical detergents, they rely on heat and steam to lift stuck-on grease and food.
Yes, a little surface rust on cast iron is completely normal and safe. Rust is just iron oxide, so it isn't toxic and won't poison your food. However, you shouldn't cook with rust as it can give your food a bitter, metallic taste.
The Short Answer. The shelf life of a grill depends largely on which material the grill is made out of, how often you use it, and how well you take care of it. With that said, entry level grills typically last 3-5 years, mid-tier grills can last about 10 years, and high-end or luxury grills can last for 20+ years.
