My friend Christal used her wire brush to clean off the grill like she normally did. She put a few burgers on the grill and they sat down and ate as a family. As she was eating the burger she felt a tickle in her throat. Well, this tickle didn't go away. It was a wire stuck in her throat causing her pain and discomfort. After 3 days she finally had to have minor surgery to have it removed. Please avoid using these. The wires are so small and almost invisible to the eye.
