I say, go get a new grill. Wife wants new grill, why yes! Go get one! lol
We had a gas grill that we didn't use for a long while (couple years). It sat covered up. We decided to start using it again and was gonna go out and clean it up. Opened it up and there was a nest in it. Pulled the nest out and closed it back up. Placed ad on craigslist for free. Guy came and got it. I told him that it had the nest in it. Helped him load it on his trailer. Less than hour later, he emailed me a picture of the grilled fired up. Good luck to him...
