Place a small amount of cream of tartar in a bowl. Add enough hydrogen peroxide to make a thick paste that sticks to the stain without running. To ensure the remedy does not discolor the enamel, apply a small amount of the paste to an inconspicuous spot before tackling the stain.
Cover the stain with the paste using a clean cloth or sponge. Make sure you cover the entire stain with the removal paste.
The hydrogen peroxide has a bleaching action and the cream of tartar is acidic to help dissolve any calcium buildup. Both require time to work. Allow the paste to remain in place for about 30 minutes.
Use a wet sponge to remove the dried paste from the stained area. Rinse the entire tub with clean water. If the stain is lighter but still remains, repeat the process to complete the removal process.
