Is It Ever Okay To Clean Your Grill While It's Still Hot? - Tasting Table
Briefly

Cleaning your grill after each use is essential to prevent deterioration and maintain the taste of your food over time. Regular maintenance makes later clean-ups easier.
Cleaning while the grill is warm helps loosen debris and grease. For flat-top grills, scrape and wipe with a wet tongs-held rag for easy maintenance.
After brushing a gas grill, applying vegetable oil and heating it allows for better coating, enhancing flavor in future meals. Regular upkeep means better-tasting food.
Properly deep-cleaning your grill before storing it away for winter avoids damage from cold weather, especially if routine maintenance has been observed throughout the grilling season.
