Rust removal, better than evaporust and 10x cheaper..

that leaves an odd color.. look pretty clean though

the sulfur helps in adding a layer that slows/prevents future oxidation... for a time. A molasses solution works well, and it's slow, giving one plenty of time to see the result and stop the process when they're ready. And similar to the citric acid formula, there is minimal reaction to the bare (un-rusted) metal so leaving it in solution longer than needed has fewer downsides.

A plus for the molasses is if you have a still, you can ferment the remaining solution and recover a refreshing beverage.

OHHH fair warning! If you do 5 gallons of it, the reaction is a bit.. intense... i spent 30 minutes mopping my garage.. foam all over.. add the chemicals in small batches, let it form then settle.. then add more.. i dumped it all in and it looked like a kids science fair volcano

Always add the acid to a base never the other way around.

Is this new molasses or older, that would have iron in it that we need. Medicinal!!!

Ha, good point, but I don't think distillation will grab the iron oxide from solution. bummer, actually. I'd love to say to my wife, I need to take my iron supplement, and then throw back a shot of moonshine from the freezer.

For the record, I DO NOT recommend distilling and drinking for human consumption, any fermentation that contains petroleum products. Even E100 fuel. The hydrocarbons from the engine oil, grease, and road grime on the surface of the rusted parts will skitter about in the molasses solution, and indeed make it into the distilled alcohol. Especially benzene.
