The wife and I have a dif of opinion … I leave the greasy debris on the grill until the next time I use it. She wants it scraped off afterwards.
My thinking is that the grease protects the grates and, when preparing to grill the next time, the burned off grease provides a good start.
Her preference is primarily based on the “ick” factor as best I can tell.
So … when do you scrape?
