I have been wrenching on things since I was a small child, over 50 years worth now and I had never heard of using vinegar to remove rust until I ran across a blog post from some guy about five years ago. I wish I had heard about this forty five years ago.
Of course I had to try it immediately and I was flabbergasted at how well it works and just how cheaply.
My biggest problem is finding containers long enough and big enough for some of the parts I would like to clean I'm going to have to invest in a 55 gallon plastic barrel with a resealable lid.
Here is a time lapse video that shows how effective it is, it will take rust out of pitted parts but will not restore the original finish on most things because the vinegar is acidic. It's also something you want to do in a well ventilated area because of the strong smell.
It is amazing to watch the rust literally fall off though.
