A Guide on How to Remove Pink Mold in the Shower

Besides the common black and green molds, a different type that you are likely to come across in your home is pink mold.

What is Pink Mold in the Shower?

If you have seen pink to reddish mold/mildew-like thing growing in your bathroom, you are actually dealing with something else. To your advantage though, the slime is fairly harmless. It comprises of a bacteria that is known as Serratia marcescens.

The biofilm is common all over the world but thrives in moist areas. Since bathrooms are rich in moisture and humidity, they provide the ideal environment. Further, the presence of soapy residues creates a feeding zone for Serratia marcescens.

Serratia marcescens is harmless to a healthy human being. All the same, it should be handled with care because it can expose people with low immunity to conditions such as urinary track infections.

As bothersome as it is, Serratia marcescens is quit difficult to eliminate permanently. Primarily, this can be attributed the manner in which it spreads. The bacteria is airborne which means that cleaning bathroom walls and curtains will not address the problem comprehensively.

After cleaning the walls, curtains and every other place in the room, the biofilm begins to grow back after some time.
