Recently I found some cast iron pots and pans outside. Problem was is they were SOOOooo Rusty! I have no idea how long they had been outside but I'm guessing years. So I went about seeing if there was a way I could save these wonderful cooking items. So here is hat I found and it worked pretty good ;O) I didn't take as many pictures as I should have because my hands were so nasty. This is NOT a clean job and I would recommend doing it outside if possible.

*Rusty Cast Irons
*Bucket Big Enough to Fit Pans
Step 1:Place all your cast irons into the oven and turn it up as high as it goes. Place them upside down and let bake for 2-3 hours! Let cool completely,which may take a couple more hours.
Step 2:Rinse well, it will be pretty dirty water and will leave your hands nasty so wear rubber gloves.
Step 3: Fill Bucket with Hot water and 4 cups of vinegar. Place pots and pans inside bucket, make sure there is enough to completely cover them. Let sit for 1-4 hours, checking every hour you can use the scrub brush to loosen the rust. Again wear your gloves!
Step 4: Rinse well again, by this point you really shouldn't have much rust left if any. Use a dark towel to dry the pan inside and out. Then place in your oven upside down for 45 minutes on 350 degrees. Let cool then pull out and rub with the towel again.
Step 5:With a paper towel rub a thin layer of cooking oil inside and outside on the pan. Place back into your oven at 350 for 15 minutes. Make sure the pan is upside down and put a cookie sheet under it to catch any dripping oil.
Your pan should be fairly new again now :O)
