What Causes Pink Mould & How to Remove It

When it comes to mould problems in the home, most people imagine black or green patches creeping across walls. But there’s another common culprit – pink mould. If you’ve noticed pinkish or orange streaks in your bathroom, kitchen, or laundry, you’re not alone. This stubborn growth is not only unsightly but can also affect your family’s health and hygiene. At Adams Carpet Cleaning, we’ve helped countless Sydney homeowners deal with mould issues, and today we’re sharing what causes pink mould and how you can remove it.

What Exactly Is Pink Mould?

Despite its name, pink mould isn’t actually mould. It’s a type of bacteria known as Serratia marcescens. This bacteria thrives in warm, damp, and poorly ventilated areas, making bathrooms, showers, toilets, and kitchens the perfect breeding grounds. It often appears as:

  • Pink or orange slimy film in showers or bathtubs

  • Streaks around sinks and tiles

  • Build-up in toilet bowls

  • Residue on grout or caulking

What Causes Pink Mould to Grow?

Pink mould doesn’t appear out of nowhere – certain conditions encourage its growth:

  1. Moisture and Humidity – Bathrooms and kitchens provide the damp environment this bacteria loves.

  2. Soap Residue – The combination of soap, shampoo, and body oils creates the perfect food source.

  3. Poor Ventilation – Lack of airflow allows moisture to linger, giving bacteria more time to grow.

  4. Dirty Surfaces – Unclean drains, grout, and tiles become breeding zones for bacteria and biofilm.

Is Pink Mould Dangerous?

While pink mould is generally less toxic than black mould, it can still pose health risks, especially for people with weak immune systems, asthma, or respiratory conditions. Prolonged exposure can cause:

  • Respiratory irritation

  • Urinary tract infections (in rare cases)

  • Skin rashes or infections

This makes regular cleaning and removal essential for a healthier home.

How to Remove Pink Mould

Getting rid of pink mould requires proper cleaning methods. Here’s a step-by-step guide:

  1. Wear Gloves & Protection – Always protect your skin and avoid inhaling spores.

  2. Scrub Affected Areas – Use a brush or sponge with warm soapy water to scrub away the biofilm.

  3. Apply a Cleaning Solution – Spray white vinegar, hydrogen peroxide, or a bathroom mould cleaner onto the surface. Let it sit for at least 10 minutes.

  4. Rinse & Dry – Wash the area thoroughly and wipe it dry to prevent regrowth.

  5. Seal Grout if Needed – In bathrooms, re-sealing grout can help stop mould from coming back.

Preventing Pink Mould from Returning

The best way to fight pink mould is to prevent it in the first place:

  • Wipe down bathroom tiles and showers after use

  • Improve ventilation with fans or open windows

  • Clean sinks and drains regularly

  • Avoid leaving wet towels or mats in damp spaces
