Would putting my chain in a can of coke overnight remove all the rust from it?

Question

I have a chain (necklace) which is a little dirty and rusty, and I was thinking since coke eats away rust, would it work if I put my chain in a can of coke overnight and get it when I wake up, removing all the rust and looking almost new?

Answer 1

Mythbusters did a show on this. They put a rusty nail in coke over night and there was not much change in the morning.  It can loosen a rusty s***w from a nut/bolt though.  But on saying that it cleaned a penny and using it with aluminum foil will scrub your metal car bumper clean

Answer 2

if it's real gold/silver....etc...it cant hurt it...not sure if it will remove the rust though..

try worlds wonder jewelry cleaner...

Answer 3

To a certain extent, any carbonated beverage will remove rust. This is because the gas used, carbon dioxide, when mixed with water, makes carbonic acid. To make rust, the iron oxidizes, which is why rust is also called iron oxide. What the carbonic acid does is drive the reaction the other way, which is called "reduction." If you read the ingredients of both Coke and Sprite, now that you know it's an acid doing the work, you can see why Coke works better - it also has phosphoric acid as an ingredient. Phosphoric acid is what does most of the work in Naval Jelly, a commercial product used for rust removal.

This is also why the rust that isn't dissolved off turns black. It's

because it's turning back into metallic iron.

It might, but it might also ruin your necklace. I don't know. Maybe try finding a place that cleans jewelry professionally in your area. A lot of jewelry and watch stores will do it. It shouldn't cost much.

You can also buy jewelry cleaning products. That would probably be safer.
