How To Remove Mold From Your Bathtub

Mold is common in our baths and can cause your water to be unpleasantly funky. Remove it before the fun begins.

We know you’ve been there before. You know the feeling. As your tub begins to feel stale and itchy, you begin to fret over the problem. The solution? With one quick swipe of your finger, you can remove the mold from your bathtub in the exact same way you’d do to an unopened bottle of antifreeze. Scientific American has learned the secret to cleaning and removing mold from your bathtub with a little help from a few friends with mold-removal expertise — and with only a half an hour of work per week, we know we’re doing something right.

It All Starts With Dirt

Before anything else can be done to your tub, you need to remove the dirt. This may be the most unpleasant task ever, but if you follow these five simple steps, you should be able to see a difference in your bathtub in no time.

First, use a soft scrub brush, such as a toothbrush, and a soft cloth. The key here is to scrub the surface very gently, and with a steady pressure. The goal is to scrub away all traces of the dirt.

Step 2: Use a Clorox Outlet Brush

These are great for scrubbing out any hard water buildup. The downside? They are more expensive than the disposable wipes in the photo to the right. This isn’t a problem for some individuals – we know – since we don’t own a home with hard water and don’t use any water softeners. But in the vast majority of cases, you don’t need them.

Step 3: Try This Stuff

We’re going to go out on a limb here and say that some of us aren’t getting paid for this (we’d be more surprised if we were). Instead, we’ll just give you the low down on this type of mold remover you can find at your local dollar store. We know that it’s not always a good idea to try one of these at home, but it did the trick for us.

First, we cut some toilet paper (with the hole cut out that you need in the toilet to make an outlet) into 1″ strips.

Step 4: Put it in the drain hole

Put the toilet paper strips in the drain hole, and put your tub, lid, and soap in a bucket of warm water. The tub should feel clean. If it doesn’t, give it a few more minutes. The tub should be a bit wet, if you wet out a piece of toilet paper, don’t worry, you just added a little more surface area to this mold-laden material.

Step 5: Go for it!

Grab your clorox cleaner and start scrubbing the tub. The key is to use light pressure that will allow you to scrape away the mold right away. As the mold grows more and more stinky, it will start to clump together and clog the bowl more easily. As you keep scraping, the longer you leave the tub, the more mold will grow on it. So work slowly, but be patient. The longer the tub is left out in the weather, the longer it will take for mold to die out. If you start to feel a “thump” in your tub after you’ve scrubbed it enough, just keep scrubbing and moving towards the next area to try and reach that “thump.”

The Clorox Cleaner Works

Now that you have your tub clean, it’s just a matter of rinsing your tub out to rinse out your mold before cleaning it.
