How Do I Remove Rust From an Old Bathtub?

Make old bathtubs usable with a thorough cleaning that removes rust.

Old bathtubs have a lot of charm, but are hard to find in good condition. Ceramic or metal tubs are prone to rust stains that can be difficult to remove. Rust removal products are available, but they are generally toxic and inappropriate for a bathing vessel. Natural cleaning methods can restore that clawfoot bathtub to its former glory.

Things You'll Need

• Scratchless cleaner
• Water
• Pumice stone
• Salt
• Lemon
• Sponge

Instructions

Using a Pumice Stone

1. 

   Use a pumice stone for safe and easy cleaning.

   Clean the tub with a sponge and scratch-free cleaner. Rinse the cleaner away thoroughly. This prepares the surface for the pumice stone.

2. Wet the area where the stain is thoroughly. Dampen the pumice stone and rub over the area. It may take a couple of minutes, so keep the stone and tub wet. Don't rub very hard.

3. Rinse completely. Run the pumice stone over the stain again, if necessary.

Using Lemon and Salt

1. 

   Salt is a natural way to remove rust from your tub.

   Clean the tub with a sponge and scratch-free cleaner. Wet the area to be treated and sprinkle it liberally with salt, coating the area. Squeeze the juice of a lemon over the salt.

2. 

   The acid in lemons helps remove stains.

   Work the salt and lemon juice together, scrubbing lightly with the sponge. Let the salt and lemon juice sit on the stain overnight.

3. Scrub with sponge again in the morning and rinse.
