How to Remove Mold From a Bathtub

Mold builds up in bathtubs over time since it thrives in areas that are wet and humid. To prevent mold buildup, air out the bathtub after each use with a fan or window and clean up standing water. Mold is a living organism that will continue to grow if left alone and can cause allergy problems such itchy eyes and a running nose. Most bathroom mold is black and gives off a musty odor -- you can kill it with bleach or vinegar. Vinegar is a natural, non-toxic cleaner.

  1. Fill the water bottle halfway with water. Fill it the rest of the way with bleach or vinegar. If the mold is thick, use a mixture of three-fourths vinegar and one-fourth water.

  2. Screw the lid on and shake the bottle to mix the solution. Make sure the nozzle is closed to avoid leaking.

  3. Spray the mold. Allow it to sit for about five minutes. The bleach should start killing the mold. If using vinegar, allow the mixture to sit for about 10 minutes. The vinegar smell disappears after 20 minutes.

  4. Wipe down the mold with the rag. Use the scrub brush to remove stuck-on mold. Pay attention to corners and underneath the faucet.

  5. Rinse with water to wash away any mold residue. Rinse out the rag and scrub brush. Add some bleach or vinegar to the laundry when you wash the rag to kill any mold that sticks to the rag.

  6. Dry off the cleaned area with a dry towel.


  • Turn on a fan or open a window when using bleach.
