Have you noticed rust creeping across your grill, making it harder to cook those perfect burgers or steaks? Don’t fire up your credit card for a new grill just yet – restoring your rusty grill could be easier and more cost-effective than you think.
With the right approach, you can bring a rusty grill back to life and get it ready for many more backyard barbecues. In this guide, we’ll walk you through the steps you can take to restore one, from cleaning off the rust to protecting it from future damage. By the end, you’ll have a grill that’s ready to perform like new.
What You’ll Need
Before getting started, make sure you have all the tools and materials you’ll need for the restoration process. Here’s a list of items to gather:
- Wire brush or steel wool
- Sandpaper (medium and fine grit)
- Grill cleaner or degreaser
- Baking soda
- Vinegar
- Scrubbing pad or sponge
- Protective gloves
- High-heat grill paint (for touch-ups)
- Cooking oil (for seasoning the grates)
Once you’ve collected everything, take the steps highlighted below.
Step 1: Assess the Damage
Before jumping into the cleaning process, take a moment to assess how much rust has built up on your grill. Is it limited to the grates, or has it spread to the body or other metal parts? If the rust is mainly surface-level and hasn’t caused deep corrosion, you can likely restore it with the steps below. However, if the rust has eaten through the metal or caused structural damage, you’ll want to consider whether certain parts need replacing.
Step 2: Give Your Grill a Deep Clean
Start by giving your grill a thorough cleaning. Remove the grates, burners, and any other removable parts and then use a grill cleaner or degreaser to scrub away grease, soot, and food residue that may have built up. This will make it easier to tackle the rust.
For areas with a lot of grime, sprinkle baking soda on the surface and use a scrubbing pad to scrub it clean. The baking soda breaks down grease while loosening stuck-on debris, making the whole cleaning process much smoother.
While cleaning and restoring your grill, be sure to avoid:
Step 3: Scrub Away the Rust
Now that your grill is clean, it’s time to tackle the rust. Here’s how to effectively remove buildup from different parts of your grill.
Grates
Grab a wire brush or steel wool and work it over the grates, focusing on those stubborn rust spots.
For more difficult rust, apply a mixture of vinegar and baking soda to the grates and let it sit for a few minutes. The acid in vinegar helps break down the rust, while baking soda adds some abrasion to the scrubbing process. Once the rust is gone, rinse the grates thoroughly with water and dry them completely to prevent future rust buildup.
Grill Body and Frame
For the grill body and frame, sandpaper is your best friend. Start with medium-grit sandpaper to break down the rust, then switch to fine-grit sandpaper to smooth the surface.
If the rust has damaged the paint, you can touch up the area with high-heat grill paint once the rust is removed. This paint is designed to withstand high temperatures, so it’s perfect for restoring your grill’s exterior.
Burners and Other Metal Parts
Rust on burners or other metal parts can impact performance, so it’s important to clean them thoroughly. Use a wire brush or steel wool to scrub these areas, making sure you remove all traces of rust. Be gentle with the burners to avoid damaging them, as they’re critical for even heat distribution.
Step 4: Season Those Grates
After you’ve removed the rust from the grates, it’s important to season them to prevent rust from forming again. Seasoning also helps create a non-stick surface for cooking. Here’s how to do it:
- Preheat your grill to a medium-high temperature.
- Once the grill is hot, use a paper towel dipped in cooking oil (vegetable or canola oil works well) to coat the grates. Use tongs to hold the paper towel and avoid burning yourself.
- Let the oil heat up and soak into the grates. This creates a protective layer that helps prevent rust and makes it easier to clean in the future.
Repeat this process every few months or whenever you notice the grates losing their non-stick coating.
Step 5: Apply High-Heat Paint (If Needed)
If you’ve sanded down rust spots on the body or lid of your grill, you may notice areas where the paint has worn away.
To protect these spots from rusting again, apply a coat of high-heat grill paint. Make sure the area is completely clean and dry before painting and apply the paint in thin, even coats.
High-heat paint is available in different colors, so you can either match the original look of your grill or give it a fresh new appearance. This not only improves the appearance but also adds an extra layer of protection against future rust.
Step 6: Prevent Future Rusting
Now that you’ve restored your grill, you’ll want to keep it rust-free going forward. Here are some tips to prevent rust from coming back:
- Invest in a high-quality grill cover to protect it from rain and moisture when not in use.
- If possible, store your grill in a covered area, like a garage or shed, to keep it out of the elements.
- Make a habit of cleaning your grill after each use to prevent grease and food residue from causing rust.
- As mentioned earlier, seasoning the grates with cooking oil helps create a barrier that protects them from rust.
