I saw this on another site http://www.safestrustremover.com and thought I would give it a try.
I was skeptical at first to say the least, but I am glad to report that it works as well as advertised. Its not a fast way to remove rust for sure, but it does remove the rust without doing any damage to the metal. If you don't have a means to sand blast something it is well worth giving it a try.
I bought the gallon jug to try, and now wish I would have bought the 5 gallon bucket so I could soak more than one thing at a time.
