I just got a cast iron tub delivered, but unfortunately, it has a few small black marks on the rim. They aren't dents or scratches in the enamel, so I'm hoping to fix this without sending it back. I've already tried using a magic eraser, but that hasn't worked. Does anyone have any other suggestions for removing these marks?

You might want to try making a paste with Softscrub and using a rag along with some elbow grease to scrub it a bit. If you want some visual help, you could upload pics to Imgur and share the link!
Another option is Bar Keepers Friend. Just grab one of those green scouring pads and give it a gentle scrub to see if that helps.
