Bacterial growth can sometimes be confused with mould growth due to certain similarities in appearance. Both bacteria and mould can form visible colonies or growth on surfaces, making it challenging for untrained and naked eyes to differentiate between the two.
In this article, we aim to discuss everything one needs to know about pink mould, understanding what it is, whether it poses any health risks, and, most importantly, how to effectively remove and prevent its occurrence.
Pink mould, also known as pink mildew or pink slime, is a type of growth usually associated with Serratia marcescens. The name is often a misnomer because the mentioned species isn't actually mould but rather bacteria that thrive in damp and humid conditions.
Pink mould often appears as a slimy, pink or reddish film on bathroom surfaces such as shower curtains, tiles, grout, and even toilet bowls. It's often accompanied by an unpleasant, musty odour.
Overgrowth of S. marcescens leads to the appearance of a pink film that's often mistaken as mould. Overgrowth occurs because the warm and humid areas of the bathroom are ideal environments for the optimum growth of pink mold.
Moreover, S. marcescens also have an abundant supply of food sources in the bathroom, such as soap scum and residues in bathing areas, faeces in toilets, and soap and food residues in pet water dishes. These substances provide nutrients for the bacteria, which, when combined with the ideal environment of the bathroom, allow them to grow and thrive.
While pink mould can be unsightly and cause a foul odour, it doesn't pose significant health risks to most individuals, especially those with intact immune systems.
However, people with weak or compromised immune systems, such as infants, the elderly, and people who take immunosuppressants after undergoing invasive medical procedures, are vulnerable to infections that this bacterial species, dubbed as opportunistic pathogens, can cause.
Some of the infectious diseases that S. marcescens may cause include:
As with any other unwanted fungal or bacterial growth in our homes, getting rid of pink mold involves a step-by-step cleaning process, which involves the following:
Before tackling pink mould, it is essential to gather the necessary cleaning supplies and prepare a suitable solution. There are several effective options to consider:
A disinfectant solution is an excellent choice to get rid of pink mould. Mix equal parts of water and a mild household disinfectant in a spray bottle. Ensure the disinfectant is effective against bacteria and mould.
Bleach is a powerful disinfectant that can effectively eliminate pink mould. Create a solution by mixing one part bleach with ten parts water. Be cautious when using bleach, as it can cause skin and eye irritation. Open bathroom windows and doors to provide proper ventilation during the cleaning process.
If you prefer a natural alternative, a baking soda solution can be effective in removing pink mould. Mix one tablespoon of baking soda with one cup of water to create a paste-like consistency. This solution is safe to use and can help eliminate odours as well.
Before beginning the cleaning process, it is crucial to protect yourself by wearing appropriate gear. Put on rubber gloves to shield your hands from the cleaning solutions and potential skin irritation. Wear safety goggles to protect your eyes from splashes or fumes.
Start by removing the shower curtains and liner if they are affected by pink mould. Place them in the washing machine and launder them on the highest heat setting recommended for the fabric. Add a cup of vinegar or bleach to the wash cycle to ensure thorough disinfection. Once washed, let them air dry completely before rehanging.
Using a soft bristle brush or sponge, apply the chosen cleaning solution to the affected surfaces. Vigorously scrub the affected areas, paying extra attention to areas where the pink mould is most prevalent. Be sure to cover all surfaces, including tiles, grout, and fixtures. For stubborn stains, allow the cleaning solution to sit for a few minutes before scrubbing again.
After thoroughly scrubbing the affected surfaces, rinse them with clean water to remove any residue from the cleaning solution and pink mould. Use a clean cloth or towel to dry the surfaces completely. Moisture is the enemy when it comes to microorganisms, so ensuring everything is dry will help prevent its recurrence.
Once the surfaces are dry, rehang the shower curtains and liner. Ensure that they're properly secured and not touching the walls or floor, as this can create a breeding ground for bacteria and mould. Regularly check and clean the curtains and liner to prevent the accumulation of moisture and potential bacterial and mould growth.
Prevention is key when it comes to pink mould. By implementing these proactive measures, you can significantly reduce the chances of its occurrence or recurrence in your bathroom:
While the steps outlined in this article can effectively remove pink mould from your bathroom, there may be instances where the infestation is extensive or persistent. Pink mould may also happen to coexist with other mold growth problems like black mold (often associated with Stachybotrys chartarum), and mould mites (click here to know more about these tiny bugs that snack on moulds) that could pose significant health risks to your family.
