What You'll Need
Organic rust remover
Hard-bristled scrub brush
Sponge
Washcloth

If you own a cast iron bathtub that has been plagued by stubborn rust stains, you may be at a loss with regard to getting rid of them while staying green. If so, you'll be pleased to know that rust can be removed from a cast iron bathtub with a few basic household tools and a little bit of elbow grease.

Step 1 - Apply Your Rust Remover

The first step in removing rust from your cast iron bathtub is to apply an organic rust remover, such as Green Bean Rusterizer, to any stained areas of the tub. Once your organic rust remover of choice has been sprayed onto the rust stains, allow it to set in for the amount of time specified on the product's packaging, then proceed with the next step.

Step 2 - Scrub the Stains

Now that your rust remover has been given ample time to sit, proceed to scrub the stains in firm, circular motions with the aid of a sponge or washcloth. Should the stains prove unyielding, you may need to incorporate the aid of a hard-bristled scrub brush.

Step 3 - Rinse the Tub

Having purged the rust stains, proceed to give the tub, particularly the formerly stained areas, a thorough water rinsing before reusing the tub.
