I have seen several videos and several posts about using vinegar to remove rust. I have often thought to try it, but one thing gives me pause. Many times you are warned that if you do not coat the metal with oil soon afterwards a "flash rust" will occur. My question is, does this process make tools more prone to rust? If it will flash rust after removing it from the vinegar solution, my mind is asking why, and why it would stop this process if the tool is not regularly coated and scrupulously cared for.
Before anyone says it, yes, I know you should maintain your tools. But if the vinegar process makes that even more of an issue, that does not sound like it would be a good thing.
Educate me, please?
