I think Rocket is a contractor and that's maybe why "standing water."
No sense in listening to guesses. Any acid should work. Oxalic for wood bleaches. Krud Kutter (phosphoric acid) is designed for rust. The vinegar suggestion is the closest here to correct, but it's weak by comparison. Baking soda is a waste of time but can be used after the acid. So could toothpaste so you know where I stand on that. A thorough rinsing should however be enough.
