It just happened, we washed it when we were done with it and the next day it was rusted. We need to get it shipped soon and can't afford to waste time trying all kinds of different things and hoping it works, I was hoping someone here had experience in actually getting it out permanently.

What's the best way to get rust off of 304L stainless steel? Somebody at work cleaned all the welds on a conveyor with a steel wire brush in a drill, and now everything he cleaned is rusted.
