What Are The Pink Stains In My Shower, Sink And Toilet?
We hear this question a lot, and we know there’s nothing pretty about pink when you see it smeared all over your sink, shower, or toilet. So what’s causing those mysterious pink under-eye circles? And why does it keep coming back after cleaning?
Although many people believe the spots are a sign of poor quality or water that is too metallically hard, they are most likely caused by a bacterium known as Serratia Marcescen.
What is the Serratia Marcescens?
Serratia marcescens is a very common species of bacteria known for its pink color and slimy texture. It can be found in soil, food, and even animals. It is transported by air where it seeks humid or dusty conditions to call it home.
Once established in a moist area, such as near your sink drain, Serratia marcescens has all it needs to survive: stagnant water, fresh air, and a steady supply of phosphates and fats (this comes courtesy of soaps, gels, shampoos). and human waste).
The appearance of pink residue in showers, sinks and toilets is more common in the summer months when humidity and temperatures are higher. This is especially true if windows have been left open for a long time.
Although Serratia Marcescens is not a pleasant sight, especially for those of us who take great care in keeping our homes spotless, the good news is that it is generally not harmful to healthy people. However, studies have shown that the bacteria is pathogenic to a small percentage of people and has been linked to urinary tract infections, wound infections and pneumonia in hospitals. It is therefore important to keep him at a distance as much as possible.
How to Clean Pink Stains in the Shower, Sink or Toilet
Once Serratia marcescens has settled on your shower, sink or toilet, getting rid of it is fairly easy with the help of a bathroom cleaning solution. However, you can also try chemical-free solutions, e.g. B. Make a mixture of one part vinegar and one part water. Simply spray the mixture onto the stained area and scrub with a soft-bristled brush (it’s important to be careful with abrasive cleaners to avoid scratching the fittings; hollowed-out surfaces are more prone to bacterial growth).
For heavier or more stubborn stains, you’ll need to apply some extra elbow grease or resort to bleach, which is a surefire way to remove that pink dirt.
Pro tip: If you’re cleaning a pink-stained toilet bowl, flush the toilet and quickly turn off the water to prevent the bowl from overfilling. This makes cleaning easier and prevents your detergent from being diluted.
Unfortunately, it is certain that Serratia Marcescens will return. So if you’re tired of seeing it and rubbing it, try to prevent it. That means making a habit of drying your sinks and showers with a cloth or mop after each use. In addition to standing water, clean all surfaces in your bathroom regularly, including your toilet bowl. Without dirt, trash, and soap scum to feed on, bacteria are less likely to grow.
Like most bacteriological organisms, Serratia marcescens cannot live in chlorinated water, so you probably won’t see any near your pool. However, over time, the chlorine will leach out of the water, which could turn the areas around your pool into a breeding ground for bacteria.
Additionally, household water filtration systems, which among other things remove chlorine sanitizer from water, have become increasingly popular in recent years, which could explain the increase in calls plumbers are getting regarding this pink goo these days.
Finally, if you have any leaks, fix them. Even the smallest droplet from a faucet can cause water to pool near the drain and allow bacteria to grow. If you suspect a leak, get out the DIY tools or call your local Roanoke, VA plumber, Wisler Plumbing & Air, for help!
