Mr. Clean Magic Eraser.
For rust stains, use Limeaway or The Works (available at the Dollar Tree). For every day cleaning, I use Comet. Scrub the comet on and let the paste dry and sit for a couple hours. Then scrub it again when you rinse it off. This will bleach your tub back to it's original white. It will work on light rust stains too. For the heavier ones, use the Limeaway or The Works.
I use barkeepers friend and a sponge it works great. And there's no smell.
I used a Mr. Clean Magic Eraser and it did fantastic. It even gets rid of rust stains.
