In summary, molasses can be used to remove rust due to the presence of oxalate-ethanedioate, which is a type of acid that is commonly used for rust removal. However, this process can be slow and the effectiveness may vary. Some people claim that molasses is an effective rust remover, while others argue that it is not as effective as other methods. Ultimately, further research and experimentation is needed to determine the true efficacy of using molasses for rust removal.

Are you mis-remembering cola sodas with extremely low pH ~2?
If you google "molasses and rust", you'll find a minor cottage industry of people promoting molasses to remove rust.

I haven't researched how effective this process is, but it is very slow, taking anywhere from several days to several weeks, depending on how much rust needs to be removed.

The chemicals listed in molasses include oxalate - ethanedioate. Oxalic acid is used to remove rust.

How else would one measure efficacy of a process? The internet, particularly as represented by G00gle, is like Alice's Restaurant, where you can get anything you want, 'ceptin' Alice - and the truth.
