I have a tin cooking pot that due to use and misuse had the tin lining worn-scraped off and it started to rust I used CLR to remove the rust, it did that but also removed all of the tin lining. I know iv'e read a post about retinning a cooking pot but can't find it now if anyone can help with how to info I would like to save this pot I know it can be used as is but would like to have the tin lining back. Thanks Duane
