What is that Pink Slime in the Bathroom?

Pink slime in bathrooms, often mistaken for mold, is caused by Serratia marcescens, an airborne bacterium thriving in moist areas. Contrary to belief, it’s not a water quality issue but an air quality one. Cleaning doesn’t eliminate it entirely, but certain practices can manage its appearance:

  • Ventilate the bathroom during and after showers.
  • Remove soap residue using an after-shower spray or squeegee.
  • Minimize moisture and soap scum on surfaces.

To tackle existing pink slime:

  1. Create a solution of equal parts vinegar and water.
  2. Apply the mixture to affected areas and let it soak for 10 minutes.
  3. Scrub away the bacteria.

Bleach can also be used but with proper ventilation. However, the pink slime might reappear after some time.

Serratia bacteria doesn’t survive well in chlorinated drinking water. Still, it can develop if residual chlorine dissipates in areas like toilets or shower curtains. Using quality water filters removing chlorine may increase pink slime occurrences.

This issue escalates in higher temperatures and humidity. During yardwork or construction, keep windows closed to prevent stirring up bacteria.

While generally harmless, Serratia marcescens can pose risks to individuals with weakened immune systems. Though rare, severe cases linked to hospital infections exist. For most, it poses minimal health threats.
