How To Clean Pink Mildew From Shower Curtain: A 5-Step Guide

Since shower curtains are often exposed to moisture, they are highly likely to harbor mildew. Here’s how to clean pink mildew from shower curtain in just five steps.

Soap alongside water that accumulates in your shower curtains makes good food for mildew. Over time, you will start to notice pink patches of mildew growing in your curtain.

This variety is called pink mildew. Whether you spot this type or the other forms of mildew, it is essential to do an effective clean-up to prevent it from spreading.


What Is Pink Mildew?

“Pink mildew” or “pink mold” is not actually a type of mold at all. It is a gram-negative bacteria called Serratia marcescens that gets its color from the pigment (prodigiosin) it produces.

Although usually referred to as mold or mildew, this pink stain in your bathroom and shower curtains is actually a type of bacteria.

Pink mildew generally appears slimy and does not always look specifically pink in contrast to its name. It can appear in a scheme of colors from salmon pink to orange or even blood red, depending on the environmental conditions as it grows.

This bacteria is commonly found in bathrooms as it thrives in areas where there is a high level of dampness, warm temperatures, and mineral deposits. Pink mildew feeds on the mineral deposits left behind by the soap we use and from fatty deposits coming from the residue of personal hygiene products.


Cleaning Pink Mildew From Shower Curtain

Getting rid of the pink stains in your shower curtains will not take up too much of your time and energy. In just five simple steps, your shower curtains will be, once again, mildew-free.


Step #1. Wash the shower curtain

Take the shower curtain off its rod and place it inside the washing machine. Before running the machine, put a couple of towels together with the shower curtain.

The towels will provide additional protection and will prevent the curtain from wrinkling.


Step #2. Add baking soda into the wash cycle

Aside from adding ½ cup of laundry detergent, our ½ cup of baking soda into the washing machine. The sodium bicarbonate component of the baking soda will kill the mildew and will freshen your shower curtain.


Step #3. Turn on the machine to a gentle wash setting

Run the washing machine to a gentle cycle. Most shower curtains are machine-safe, but still, they require special care. To be sure, check the tags of your curtain before you proceed with machine-washing.


Step #4. Add undiluted white vinegar

As you start the first rinse cycle, add 1 cup of distilled white vinegar. The acetic acid component of the vinegar will create a reaction with the baking soda you used previously, killing the mildew more effectively.


Step #5. Dry the shower curtain thoroughly

After rinsing, take the shower curtain off the washing machine and hang it to dry. No matter the circumstances, never put the curtain in a dryer.

If you still notice visible pink stains after washing, rewash the shower curtain. This time, add ¼ cup of detergent and ½ cup of bleach instead of baking soda and vinegar.

Just like vinegar and baking soda, bleach is also known as an effective home remedy to mold and mildew. It can be more pungent in smell, so be extra cautious when using it.
