The tub is over 100 years old and is stained pretty badly. I read some of the ideas and comments on this post from the Money Saving Mom about cleaning the stains. I decided to try a combination of Bar Keepers Friend and a Mr. Clean Magic Eraser. When you see the after pictures you will see what a difference it made and that I also need to repeat this several times. The Magic Eraser completely disintegrated though and I didn't have another. I'm a tad embarrassed to be posting these pictures but it is my house and I am working to get it cleaned.
