Do you have the original image and which areas you want fixed. I was wondering why the hard water streaks were repeated all over the place. Quite confusing.
Also, I have circled the various areas of problems. Which areas are you looking to fix. Note that the originating issue does not appear to the the tiles yet the water streaks on the glass doors to the tub/shower area.
My estimate is that this is a pretty decent amount of work depending on what you need done. If you are getting paid by the image and not by the hour, this may turn out to be not a great return on your time investment. Just a thought to consider.
