Every householder should be aware that one of the most efficient strategies to battle mold is to have a regular cleaning program. Mold thrives in small, confined places such as tile corners, grout, and around drains in your bathroom. Knowing the type of mold in your house will help you choose the best strategy to keep the spores from growing. Keep reading to find out more!

All About Pink Mold

Do you have pink or rust-colored blotches in your shower room? Your bathroom might be infested with pink mold. These patches are ugly fuzzy or slimy masses that come in a range of colors. A pink color, on the other hand, generally indicates that the mold has been there in your washroom for rather some time.

Pink stains in your bathroom can be caused by a number of things, the most frequent of which is the Pink Mold, Serratia Marcescens. This bacterium can create filthy colonies, but they do little to no harm to healthy people.

What Causes Pink Mold

Pink stains are generally always caused by water and incorrect cleaning. Pink mold germs may leave stains on white materials, making them difficult to clean. The bacteria feed on organic material and prefers damp, humid environments where it may develop rapidly. Pink mold is an airborne bacteria found in soil that feeds on organic material.

Bacterial spores are most probably in your damp bathroom, where the pink mold thrives on soap scum and organic materials in wet locations around your bathroom. The bacterial growth causes the pink color to become red, indicating that the colony has increased significantly in size.

Pink Mold Vs Black Mold

Unlike common green molds such as Cladosporium or the famed lethal black mold, Stachybotrys chartarum, the pink “mold” in your shower is not mold at all. The discolouration is caused by a biofilm of Serratia marcescens, which is a bacterial colony. The bacterial species thrives in wet conditions, such as showers, where it feeds on mineral deposits in dirt and grime and fatty compounds in soap and shampoo waste.

Health Concerns

While most normal people’s skin may come into contact with the pink mold in a narrow shower, it can cause serious illness (i.e., urinary tract or bladder infections) if it enters the bloodstream through the eyes or skin wounds. People with weakened immune systems see an increase in the intensity and range of these diseases. Better to be safe than sorry!

Rust is another prevalent stain, in addition to Serratia Marcescens.


Though rust is often a strong red-orange hue rather than pink, the color might be diluted or misunderstood as pink. Rust occurs on wet metallic areas and can inflict painful sores on the skin when rubbed against the rough surface of rust.

If the stain is caused by rust, you must locate the source of the rust to permanently remove the spots. A plumber, maintenance agency, or house inspector can help you determine the source of the rust, and you will need to have these corroded spots removed or fixed to keep the rust far from your shower surfaces.

Pink Mold

If you have stained a white bathroom fixture with a colored dye, you may easily remove the pinkish remains by using a bleaching solution like a bleach pen or hydrogen peroxide (never both!) immediately on the discolored regions. Be cautious not to leave the bleach on for too long, since residual chlorine bleach will aggravate pink stains!

Luckily, the light pink to dark red color (due to the color produced by the bacteria) makes it easier to detect and eliminate from showers, shower doors, curtain liners, walls, floors and counters. Pink mold on hard and soft shower surfaces may be removed and prevented from returning using common home products and the ways outlined here.

Baking Soda

Suit up and use baking soda to scrape the biofilm off of hard shower surfaces.

Unfortunately, Serratia marcescens’s tenacious biofilm can only be cleared with some elbow grease.

  • In a small bowl, make a somewhat runny paste using a 1/4th cup baking soda and a tablespoon of liquid dish soap.
  • Wear gloves, safety glasses, and a mask (as seen on Amazon), then dip the bristles of a soft-bristle scrub brush into the mixed paste and thoroughly scrub off any visible spots of biofilm on hard surfaces in the bathroom. The biofilm should be loosened and cleared throughout this approach.
  • When you are through cleaning, either wipe down the scrubbed regions with a damp cloth or switch on and disconnect the shower head to flush the gunk down the drain.

Chlorine-based Bleach

It is not sufficient to merely scrub the color away; you must clean the area to eradicate any leftover bacteria and prevent it from returning. Bleach is your safest choice because it kills the rest of the bacteria while also dissolving stubborn stains left behind.

  • Fill a twelve-ounce spray bottle halfway with chlorine bleach powder and warm water, then reattach the top and carefully shake the bottle.
  • Allow the solution to sit in the shower for ten minutes after spraying it directly on the hard surfaces of the shower that you have cleaned.
  • Then, using a clean soft-bristle scrub brush, softly scrub the sprayed regions.
  • Wash again, and dry the areas with a clean rag or sponge.

How to Keep Your Bathroom Free from Pink Mold

Once the present pink mold has been removed, the next issue is to keep it from returning. Pink mold germs like to get into fabrics such as shower curtains, shower curtain liner, and any flooring in the region. Towels, also, can harbor pink mold germs, which is why you should wash them often.

To keep pink mold at bay, use a cleaning mist or a disinfectant that will destroy any germs or spores before they settle into the cracks and crevices of your washroom. Using one of these treatments on a regular basis keeps mold and germs at bay while also cleaning your bathroom of dangerous microorganisms.

In conclusion, Serratia Marcescens is not a highly dangerous bacterium, but it can still cause certain health problems. It is preferable to get rid of the biofilm before the bacteria grows and your contact with it grows. My thorough guide explained how to remove pink stains from bathroom fixtures. If you feel like the DIY solutions are not for you, contact a professional disinfecting firm that can remove the pink mold and restore the luster to your washroom.
