Molasses for rust removal

Hey guys, so we all know how rust is a word synonymous with many land rovers. Well recently I hear that a molasses bath works to remove rust. Has anyone else heard of this rust removal solution? Any info would be great.

There's always a used motor oil bath. Should only take about 5 years soaking or so.

But in all seriousness, if molasses works, go for it! I'd be interested in just knowing.

I'll try it out in the sometime this month when I have the time. I'll use a rusty Ford Model T piston I found in a barn, so that should bring out the truth. In truth, this experiment will probably be slow as well.... Molasses

Curious what you need to derust? Small parts? Don't say chassis.

Vinegar works, coca-cola work as well, all acid food should work. Just depends on how long can you wait and how much it will cost!

Don't waste your effort. Just get some phosphoric acid from your local chemical supply. Make up a solution in a bucket and get r dun

2x phosphoric. even at a concentration of 10% it has not failed to derust even the disgusting look rusted parts. just don't leave it in too long because it will dissolve bare metal (albeit at a much slower rate than hcl.)

This guy did it...and then he gave up and just took the thing to get sandblasted. Save yourself the trouble and blast.

Yes, it works. I've been playing around with all the different ways to remove rust. Molasses, vinegars, sodas and electrolysis. They all work really well. I've been able to save just about every nut and bolt on my truck; meaning I didn't just grind them all off to be fast. I mentioned to a friend of mine that I was trying to decide how to clean them and he suggested tumbling. He's a car restore person too. Yes, I'm being uber geeky on it and want to reuse and save as many of the original parts as possible.

Here you go. On another forum people mentioned that ketchup and cola will even work. From my experience the shape of the item, the severity of the rust, the temperature and dilution of whatever mixture you are using determines the amount of time it needs to soak.

Why does molasses remove rust
