How to Clean Rust Out of a Porcelain Tub

No amount of bleaching and scrubbing will remove rust stains from a porcelain tub, and using harsh abrasives or chemicals will damage the sensitive surface. There is a way to remove this unwanted addition to the tub using common, gentle products. A little toothpaste and baking soda will remove the rust and leave the porcelain finish looking bright and clean. Many homeowners are able to remove this unsightly stain in a matter of a few minutes.

Things You'll Need

• Toothpaste
• Baking soda
• Scrub brush

Instructions

1. Wet the rust stain with water. Squeeze out a small portion of regular toothpaste and smear a layer over the rust stain.

2. Sprinkle a layer of baking soda over the toothpaste. Mix the two into a paste with your fingers over the stain. Allow the paste to sit for 20 to 30 minutes.

3. Scrub the area with a small scrub brush. Rinse with cool water. Reapply the toothpaste and baking soda paste to any remaining stain and let soak for 10 to 15 minutes more. Repeat scrubbing and rinsing until the stain disappears.
