If black spots start appearing on your tub or shower walls, you
have a mold or mildew problem. Get rid of it naturally with this simple
concoction (and some elbow grease).
1 cup baking soda
2 cups water
1 cup white vinegar
In a bowl, mix 1 cup of baking soda and 2 cups of water into paste.
Apply the paste to areas in your bathroom affected by mold. Use the Tub Scrubber to work the mixture into grout and tight corners.
Rinse the treated areas with water. If white residue from the baking soda remains, rinse again with 1 cup of white vinegar.
