Does Vinegar remove rust ?

After $50 in vinegar and wearing out 3 wire brushes, it's looking pretty good. Not having a tub big enough for that large peace, I thought I'd dig a hole in the ground and line it with a large trash bag. After two attempts with two bags, I gave up because the vinegar ate thru both. So, I bought a cement mixing trough at Lowes. Then lastly, till I find a spot inside for it, it's going to set outside on the porch. To stop anymore rusting, I'm trying the seasoning thing, of all the parts like a cast iron skillet, seems to work great. Time will tell though.
