Most likely causes (in order)

Fix 1: Clean surface rust

Light rust comes off with a wire brush and heat. This is the most common case.

1. Heat the grill on high for 15 minutes with grates inside.
2. Use a bristle-free grill brush to scrape rust off.
3. Wipe with a damp cloth.
4. Season with oil (see prevention section).

• GRILLART Bristle-Free Grill Brush — Cleans grates without wire bristles.
• Weiman Grill Cleaner Spray — Food-safe rust cleaner.

Fix 2: Remove deep rust

For heavier rust, remove grates and treat off the grill.

1. Remove grates from the grill.
2. Soak in a mix of white vinegar and water (50/50) for 1 hour.
3. Scrub with a wire brush or steel wool.
4. Rinse thoroughly with water.
5. Dry completely (this is critical).
6. Re-season with high-smoke-point oil.

Fix 3: Replace fully corroded grates

If a grate breaks under pressure or has holes, replace it.

1. Measure the exact grate dimensions.
2. Note your grill make and model.
3. Order OEM replacement or upgrade to cast iron for longer life.

Fix 4: Prevent future rust (season and cover)

Constant re-rusting means your grates are not sealed against moisture. Season regularly and cover the grill.

1. After cleaning, apply high-smoke-point oil (avocado, canola, flaxseed) with a paper towel.
2. Heat the grill until oil smokes.
3. Cool and repeat 2-3 times to build a seasoning layer.
4. Cover the grill when not in use.
5. Store indoors in extreme humidity or winter climates.
