Can I save this Bathtub?

[Josh L.]

Is there any way I can save this bathtub?

Several applicants have commented about this bathtub, mainly about the leaf shaped things on the bathtub. It just looks dirty, irregardless of how clean it actually is.

I've tried scrubbing and scrubbing it, but it won't come off. What else can I do to get rid of those things?

If I can't do get rid of them, then it seems like I'll either need to get a new bathtub or re-surface it. 

But, from what I've read, re-surfacing seems like a bad idea for a rental because that process leaves the bathtub more vulnerable to damage and it starts looking bad after a number of years.

I'd really like to save and keep this bathtub, but I have no idea how I can clean it and get rid of those things.
