Last night I came home drunk and thought it would be a really good idea to clean my shower, I emptied a bottle of limescale remover all over my shower.
Unfortunately, I didn't see the bottle says "not suitable for stainless steel" because of the hydrochloric acid.
Now all the metal parts of the shower are forgeted, below is a photo of the bar that holds the shower head, it looks a lot worse in person which you can't really tell in the photo.
The real problem: I move out in two weeks, they're going to forget me with my deposit if I don't make this look reasonably decent. My apartment is only two years old, and they knew that it wasn't forgeted before I moved out.
Any idea what I can do to restore the stainless steel?
