It's generally best to clean your grill grates while they are still hot, but not scalding hot, as the heat helps loosen food particles. Wait about 10-15 minutes after grilling to allow them to cool slightly.
Cleaning grill grates while they are hot offers several advantages. The residual heat softens and loosens any stuck-on food residue, making it easier to scrub away. If you wait until the grates are completely cold, the grease and food particles will harden, requiring significantly more effort and potentially damaging the grates.
Here's a step-by-step guide to cleaning hot grill grates:
Avoid using excessive force when scrubbing, especially on porcelain-coated grates, as this can damage the coating and lead to rust. Consider using a nylon brush for these types of grates.
