What is the pinkish residue on my bathroom fixtures?

A pinkish film or residue is most likely an airborne bacterium called Serratia marcescens. These bacteria are not present in the water supply. They are naturally present in the environment and may appear during new construction or remodeling work due to the dust and dirt stirred up by these activities. They thrive on moisture, dust and phosphates. The best way to control these bacteria is to clean the effected surfaces with bleach, or a cleanser containing bleach, and keep the area as dry as possible.
