"Hey. I had a little accident. Do you have anything to get rid of iodine stains on my t-shirt? Putting it in the washing machine didn't help."
Sure. I still have some Na₂S₂O₃ in stock from the time when dark rooms were still a thing.
I dissolved some of the stuff in warm water, gave the solution to the lady and instructed her to pour it over the stains, rinse it afterwards and put it in the washing machine again.
She now thinks that I'm a magician of sorts.
