How to Make Metal Rust With Potatoes

I've been working on a project that required me to make some nails and hardware rusty. I wanted to go the easiest route (of course) so I tried the vinegar and salt method which I had used before, but it just wasn't happening fast enough, meanwhile, my husband was chopping potatoes for stew: lightbulb!
The metal started to turn dark immediately and after soaking for about an hour, I took them out and rust

    Why for Pete's sake would you ever want metal to rust?

      Rust as a decorative finish is used in many altered art projects. I myself make metal garden orbs and one of the most popular finishes is a rusted orb. You rust it then seal it well so it doesnt continue to rust .....but what a lovely aged look it gives to the orbs

      So many things look best when rusted. Great idea!

      Are we not concerned about Tetanus anymore? I stepped on a rusty screw in my back yard a few weeks ago it didn't break the skin but it was a reminder that I was behind on my shots.

      Nadine: Everyone should have a Tetanus shot (DTaP) every ten years, whether they come in contact with rust or not. It's a combination of Tetanus, Diptheria, and Pertussis vaccines. Pertussis is particularly important if you come in contact with young children.

      You don't get tetanus from rust. You get it from metal that is left outside in 'yucky' conditions that causes the metal to rust. So it's the 'yuck', (for lack of a better word) surrounding the metal which causes the rusting process that might create tetanus. It's not JUST because something is rusty.

      Hope that makes sense

      I also think the 'rusted' look is great on some projects!

      @Rainy Odessy I had no idea that apples would work too. I will be trying your method. Thanks so much for sharing and I'm sorry for the delayed reply~ Amy
