Hi Janet. Glad you deleted the first post. I knew it wouldn't show up right away but when I made the first post I got a message box that told me I needed to be signed in to do that. I thought it took me so long to make the post that I timed out, so I re-made the post. Seems like no matter how much I read about this metal mess I still don't understand it. I thought the metal out product would get it out once and for all so thank you for clearing that up for me. Am I correct in thinking that once I find a product that works to clear the brown out I would use it weekly as a maintenance product?
