I always clean out my grill as soon as the residual coals die out and cool down. But we got this storm and I did not have a chance to do it, other than scraping the grate nice and clean. I always keep it covered, but now that I have the rotisserie frame rain can get in there, which it did. I don't have any place to store the roti frame, so it stays on the grill with the lid on it. I keep the spit and motor in the house.
I wiped it all out thoroughly and then put it in the sun to dry further. It looks pretty good now, but I just wanted to be sure I won't kill my lawn if I decide to hose it down
