Barry,

I will have to choose among one of three rust-removal techniques for my next project (in a few years): molasses, electrolytic, or a a large sandblasting cabinet.

A manufactured cabinet is expensive and requires a large compressor. Molasses is not cheap where I live. Setting up the electrolytic bath would be cheaper for me.

I've got nothing against molasses. If it works and the price is right, use it. By the way, my bet is that your feed-grade molasses is sulphured. Here is a link that briefly notes the rust-removing and chelating properties of molasses.
