Plumber working on a sink

Have you spotted pink stains around your toilet or sink? While this might be alarming, it has a pretty simple explanation. If you’re a resident of Tempe, Phoenix, or the surrounding area in Arizona, learn more about pink water residue in your bathroom, what causes it, the potential issues that come from it, and – most importantly – how to fix it.

What Is Pink Water Residue in Bathrooms?

Pink water stains in bathrooms are often caused by Serratia marcescens, a bacteria that thrives in damp environments. Bathrooms’ constant moisture makes this bacteria perfect for growing, leading to pinkish marks around sinks, toilets, and tubs.

While generally harmless, Serratia marcescens can pose health risks for people with weakened immune systems. If it enters the body through cuts or the respiratory system, it can cause infections. Keeping your bathroom clean and dry reduces these risks and maintains a healthy space for you to do your business.

Causes of Pink Water Residue in Bathrooms

Pink water residue isn’t just about Serratia marcescens. High humidity and poor ventilation are major factors, especially in bathrooms where moisture from showers and baths can build up quickly. This is particularly true in Tempe and Phoenix, where the dry climate contrasts with indoor humidity.

Hard water is prevalent in much of Arizona, which also contributes to this issue. Minerals like calcium and magnesium in hard water can leave deposits that provide surfaces for bacteria to cling to, encouraging those pink stains.

How to Treat Pink Water Residue

A good cleaning routine is the best way to tackle pink water residue. Use a mix of baking soda and water to scrub the stains gently. For stubborn spots, a diluted bleach solution can work well. Apply it carefully, let it sit, then scrub and rinse thoroughly.

Choose cleaning products that are safe for your bathroom surfaces to avoid damage. Regular cleaning on a weekly basis helps keep these stains at bay. Deep cleaning once a month is also effective, both for preventing pink stains and for general cleanliness.

Preventing Pink Water Residue

Prevention is even more effective than cleaning, so finding ways to stop pink residue before it forms is always the preferred way to deal with the issue. Focus on reducing the moisture levels in your bathroom. Start by ensuring proper ventilation; installing a high-quality bathroom fan can significantly help in keeping the air dry. Make sure to use the fan during and after showers or baths to minimize humidity. Additionally, consider using a dehumidifier, especially in areas prone to retaining moisture.

Regular maintenance also helps. Check for any leaks in your plumbing and address them promptly to prevent water accumulation. Wiping down wet surfaces after use can also deter the growth of Serratia marcescens. By keeping your bathroom dry and well-ventilated, you create an environment that’s less conducive to bacterial growth.
