How do I remove rust from grill grates?
Quick answer
Remove light rust from grill grates by brushing with a stiff nylon or brass brush, washing with mild soap, drying fully, and applying a thin high-smoke oil coat before heating 15 minutes. Deep rust pits on thin wire grates mean replacement time — rust weakens metal and flakes into food.
Rust removal steps
- Remove grates and brush loose rust outdoors.
- Wash with mild detergent; rinse and dry completely.
- Coat with vegetable or grapeseed oil.
- Heat on grill medium 15 minutes; cool and wipe excess.
Prevention
Keep grates oiled, covered, and stored dry. Stainless grates rust less but still need cleaning.
