As for the grinder talk. I was at the grocery store with my daughter and she tells me I have something stuck in my neck. She reached over and pulled it out. I thought she was messing with me because it felt like she pulled out a deep rooted hair. Then she showed me a a wire that somehow flew off the cup brush and stuck deep in my neck behind my ear. I also scraped my hand but I'm not sure if it was grill cleaning or a previous thing. I will do something to myself when working and not realize it until sometime later when I'm done.
On that note I think I'll get at least a paper mouth and nose mask for the next time. And a face sheild to better protect myself. I already wear glasses, and I thought that would be good enough for eye protection. However after having a wire go around my head then into the back of my neck I'm thinking more protection is good. I saw the picture Bruce posted and it's true. You get nasty grinding on those things.
