The Guide on How To Get Rid of Pink Mold

Many different kinds of mold and bacteria can appear in your home or workplace. While most are harmless, some can make the inhabitants very sick. And no mold or bacteria is pleasant to be around. Long term, most molds can cause respiratory stress and worsen allergy symptoms, so it’s important to get rid of them when they do appear.

Our cleaning Pros have seen it all, and have some top tips for getting rid of different kinds of mold. In this post, they share their secrets to identifying and tackling pink mold. Learn what pink mold is, what causes it, and how to get rid of it now!

What is pink mold bacteria?

Pink mold isn’t actually a mold at all. It’s a type of very common airborne bacteria. It’s found all over the world and just loves to hang out in dark, damp places indoors. In most houses, pink mold appears as a slimy buildup, and it might not be pink at all. The color of pink mold comes from the temperature of the room and can vary from orange to bright red.

The bacteria that cause pink mold is called Serratia marcescens. It was first identified in Italy in 1819. Today, pink mold is a common sight in bathrooms and other damp places. It’s also responsible for 1.4% of hospital-acquired infections in the US. Pink mold bacteria feed off fats like those found in the residue of soap and shampoo.

Is pink mold dangerous?

In humans, pink mold is more of a nuisance than a danger, although it can cause some nasty infections. Many of these happen in people who are already immunocompromised, which is why pink mold causes lots of hospital-acquired infections. The most common sites of pink mold infections are in the urinary tract, respiratory tract, eyes, and open wounds. This can lead to UTIs, pneumonia, conjunctivitis, and tear duct infections. 

For most people, pink mold is relatively harmless, but it’s still important to get rid of it as soon as you notice an outbreak. Even people who are healthy and have a strong immune system can develop pink mold allergy symptoms. These include:

  • Sneezing
  • Runny nose
  • Congestion 
  • Itching or rash
  • Dry, scaly skin
  • Eye irritation
  • Coughing
  • Worsening asthma

Long-term exposure to any mold or bacteria is bad for your health, and that can put you more at risk of serious side effects.

How to kill pink mold

If you’ve spotted pink mold in your bathroom, don’t panic. You can kill it with simple household cleaning products. The best product to use is bleach. Bleach can kill pink mold bacteria, and also tackle any stains it leaves behind.

Step 1: Identify the extent of the pink mold infestation

Step 2: Use protective clothing like rubber gloves, a mask, and glasses

Step 3: Make a solution of 1.5 cups bleach to 1 gallon of water

Step 4: Use a sponge or spray bottle to apply the solution liberally to the mold

Step 5: Let the solution sit on the mold for 1 hour

Step 6: Use a scrubbing brush to remove the mold

Step 7: Wash down the surface with clean water and dry with a microfiber cloth

This solution will work on most common surfaces, like baths, faucets, and bathroom tiles. If you notice pink mold on your shower curtain, follow our Pro tips on how to clean a shower curtain to get rid of the mold.

To prevent pink mold from returning, make sure to stay on top of your cleaning routine.

how to clean pink mold in a humidifier

How to treat pink mold in a humidifier

Another place you might spot pink mold is inside a humidifier. Pink mold loves the damp, dark atmosphere. Our Pros don’t recommend using bleach inside humidifiers. Remember anything that goes in there can end up aerosolized and breathed in by anybody nearby. Bleach can also leave an unpleasant odor behind that will make the whole room smell like chemicals. Instead, follow these tips to get rid of pink mold in a humidifier.

Step 1: Unplug the humidifier

Step 2: Remove the tank and fill with a 50/50 mix of water and white vinegar, let sit for 30 minutes

Step 3: Disassemble any other removable parts and soak in the same water and vinegar solution

Step 4: Use a brush dipped in the water and vinegar solution to scrub the interior of the humidifier

Step 5: Use plain water to clean the inside of the humidifier and rinse the removable parts

Step 6: Dry all the parts and reassemble the humidifier

Proper maintenance is important for keeping your humidifier clean and free from pink mold. Follow our Pros’ tips on cleaning and maintaining your humidifier

Don’t like the smell of white vinegar? You can also use 3% hydrogen peroxide instead. Just use 50/50 peroxide and water as a cleaner. Don’t mix hydrogen peroxide with white vinegar, as this can create peracetic acid. Peracetic acid is an irritant that can harm your skin, eyes, and lungs.

How to treat pink mold on food

Although pink mold prefers wet environments like bathrooms, you could find it living on foods like bread and dairy products. If you find pink mold on any food, throw it away. It isn’t safe to eat, even if you cut off the moldy section.

Sometimes mold gets onto food somewhere in the manufacturing or shipping process, and it’s just bad luck. But if you regularly find pink mold on food, look for the underlying cause. This could be a leak where you store your food, or your fridge isn’t maintaining a low enough temperature. Finding and resolving the underlying cause should get rid of your mold problem.
