Dealing with pink mold in your bathroom? This stubborn slime—which is actually bacteria, not mold—is commonly found in damp and humid environments and is why it often shows up in bathrooms. Fortunately, with a little elbow grease and a few habit changes, you can remove pink mold and make it less likely to return.
1. Moist Surfaces
The bacteria that causes pink mold thrive on wet surfaces, including in and around toilets, on shower walls, and near drains. You might also notice this type of mold on your shower tiles, faucets, and shower curtains.
Of course, you can’t get rid of all the moisture in your bathroom (for example, your toilet bowl will always be wet). However, there are ways to remove pink mold and reduce the chances of it coming back, even in the wettest spots of your bathroom.
How to Fix It
To get rid of pink mold in a shower or another moist area, follow these steps:
Put on rubber gloves, safety goggles, and clothes that cover most of your skin.
Turn on your exhaust fan and open any doors and windows in your bathroom.
Combine baking soda and dish soap in a 4-to-1 ratio in a small bucket.
Apply the mixture to the areas with pink mold using a scrub brush.
Rinse the scrub brush with hot water to remove any leftover mold.
Rinse the areas you scrubbed with a removable showerhead or clean water in another bucket.
Inspect the area again. If there’s any remaining pink mold, repeat the previous steps.
Remove the shower curtain and liner if you’re cleaning a shower and place them in the washing machine with bacteria-killing detergent. When done, hang them out to dry.
Use a commercial disinfectant spray or homemade mold-killing vinegar solution to clean the entire shower, toilet, sink, or whatever other area you’re cleaning. Let it sit for at least 10 minutes.
If there are any more pink mold spots, clean them with a scrub brush.
Rinse the entire area with hot water.
Dry the surface with a clean towel, cloth, or squeegee.
Rehang your shower curtain and liner if you washed them.
To limit moisture (and, potentially, pink mold) in your bathroom, dry your shower walls, doors, and bathtub after every use. If you have a shower curtain, close it after every shower.
2. Lack of Ventilation
Poor ventilation also promotes pink mold growth. If your bathroom doesn’t have an exhaust fan or windows, you might notice pink mold in different parts of the room.
How to Fix It
Follow the steps listed above to clean pink mold from your bathroom surfaces. To reduce the chance of it returning, make sure to run your exhaust fan during and after your shower. Don’t have an exhaust fan? Leave a window or door open after showering.
3. Soap Residue
Pink mold-causing bacteria feed on soap scum and shampoo residue, which is another reason you’re likely to find this type of mold in your bathroom. For this reason, you might also spot pink mold in your kitchen or laundry room.
How to Fix It
Use the directions listed above to banish pink mold from your bathroom surfaces. To limit the amount of soap scum that bacteria can feed on, it’s best to clean your bathtub, shower, and sink at least once per week.
When to Call a Pro
Whether it’s in your shower, sink, or toilet, getting rid of pink mold in a bathroom is fairly simple. You’ll just need to put on your safety gear and start scrubbing.
However, you can always call a professional if you don’t feel comfortable cleaning mold yourself or you aren’t sure which type you have. In those cases, a local mold testing and remediation pro can identify the type of mold and take the right steps to remove it.
Frequently Asked Questions
While it isn’t as dangerous as black mold, pink mold in the shower or elsewhere still poses some health risks, particularly for people with compromised immune systems. Even if you’re in good health, pink mold could cause an infection if it gets into your eyes or penetrates your skin through an open wound.
Yes, you can use vinegar to remove mild pink mold infestations. Instead of using a commercial mold-killing product, you can mix one part white vinegar with one part water in a spray bottle. To get rid of the mold, apply the solution to the pink mold and let it sit for up to an hour. Then, scrub it off with a brush and rinse the entire area with hot water.
