Your what?!?! Cast Iron...Rusted!!!

We all know what it means when you're tin roof is rusted thanks to the B-52s, but what does it mean when you're cast iron gets that way? If you said throw it away and get another one, I just have one question. Can I borrow $50? Obviously you have disposable income.
Seriously just because it gets a little rusted doesn't mean its over, just ask Keith Richards.

Here is the best and easiest way to make your pan rust free.

Using equal parts, vegetable oil and salt, pour a little vegetable oil in first and then sprinkle your salt on top. Now you just scrub. The salt is your rough abrasive agent, so all you need is paper towel or a sponge to scrub with. I prefer the paper towel since you can toss it in the trash. Add more oil or salt if need be. Once your done scrubbing wash it with a good mild grease tackling dish washing soap and water like a normal pan. Last, just dry it really well. That's it. Seriously. Now go fry something.
