Yep! Didn't believe it till I tried it. It's a sweet deal price wise, never would have thought, but the proof of the pudding was in the eating thereof!!

When it ferments it forms acetic acid. This works on the oxygen in the rust, and turns the rust to jelly. It will get to rust in places you can't reach.

You need to fully submerge the part in a piece of wire or hook. Leave for 3-4 days. A good scrub with a wire brush whilst you hose the part off with water and the metal comes up like new! It will still have scars/pockmarks from the rust, but the rust is gone. Paint or oil it quickly, because the metal is so clean it will flash rust when it dries off.

After that you can distill the molasses and enjoy a long cool Rum'nCoke whilst you admire your shiny car parts !
