How to Remove Stains from the Bathtub


Eva asked: How do I remove an orange stain from the bottom and one side of my acrylic tub? It is only on the side which has the shower curtain and most of the bottom. I have tried Scrub Free, bleach and vinegar with no luck.

Stains in the bathtub can occur for several different reasons. Sometimes the water gets trapped and doesn’t dry completely, leaving a moist area for bacteria to grow. Other times, these tough stains are actually mineral deposits that are left behind from hard water. In either case, there are a couple of different methods that can be used to remove the stains and restore your bathtub to its original brilliance.

Dry Cleaner Method

You Will Need:

Steps to Remove the Stains:

  1. Begin by mixing a paste with the Comet powder and water. It should be thick enough that it can be spread over the stains on the side of the tub with minimal dripping.
  2. Apply the paste to the stained areas and allow it to set for several minutes.
  3. Moisten the Mr. Clean Magic Eraser with clean water and use it to scrub the area that has been soaking.
  4. The combination of the Magic Eraser along with the dry cleaner are often effective in removing the mineral deposits and stains that can be otherwise difficult to remove from the surface of the tub.
  5. When the stains are gone, rinse the entire area with clean water until all of the cleaning residue is removed.

Baking Soda and Peroxide Method

You Will Need:

  • Baking soda
  • Hydrogen peroxide
  • Water
  • Nylon scrubber

Steps to Remove the Stains:

  1. This method also utilizes a paste, though this time it is made of two parts baking soda and one part hydrogen peroxide.
  2. Spread this thick paste over the stained areas and allow it to set for at least 30-45 minutes.
  3. After the paste has had plenty of time to set and soften the mineral deposits, scrub them away using a nylon scrubber.
  4. When the stains are removed, rinse the area completely with clean water.

Additional Tips and Ideas

  • There are commercial cleaning products as well, but they are often caustic and are very harsh. If you choose to use one of these products, ensure that the tub is completely rinsed out prior to use.
  • Vinegar has a natural acid in it that makes it effective in removing many of these deposits and stains. It may be more effective if it is allowed to soak on the stain. An easy way to accomplish this is to moisten some cloths with the vinegar and lay them over the stain for up to an hour before attempting to scrub away the deposits.
  • Orange stains can also be caused by iron or rust from the pipes. To remove, follow the guidelines above. If iron in the water is the problem, it may be helpful to explore filtration systems to filter the water.
  • If iron is the problem, you will most likely see the effects in other areas such as laundry items turning yellow or orange, discoloration in the dishwasher, etc.

    I have terrible stains in my bathtub from my boyfriend working at a place where they make crankshafts for large things like trains and ships. The stains are from the powder graphite lubricant that they use for the press. I have never been able to get the stains out and I think the baking soda-peroxide mixture might just do the trick since I can leave it to set right on the stain.

    Thank you so much for this article!

    Never, ever use an abrasive cleanser like Comet on an acrylic tub. You’ll scratch it horribly.

    The dry cleaner method worked beautifully on my very stained tub (a combo of hard water stains and soap scum). I left the Comet on overnight and in the morning the stains came out with just a little scrubbing. It has been stained for so long and now it looks great! Thanks.
