​​Pink Stains - How to Get Rid of Them

The bacteria most likely responsible for pink stains, Serratia Marcescens survives when any water sits for a period of time in the open air. This is why pink toilet bowl stains are so common. 

There are several things you can do to prevent these pink stains from appearing. Drying wet surfaces after use will prevent the bacteria (Serratia Marcescens) from growing. For toilets, simply squirt toilet bowl cleaner around the rim of the toilet bowl and leave it for approximately 5 minutes. Next, with a soft bristle brush, apply light pressure against the bowl surface. Clean the bowl thoroughly the bowl and flush.

For harder to remove stains you can use regular household bleach and a soft bristle brush to gently scrub the affected area. Avoid being too aggressive with cleaning solutions or abrasive methods as some cleaning methods may scratch and even remove the protective coating, sealant or finish on toilets. Thus making them more susceptible to staining, mold or mildew, bacteria growth, and mineral deposit rings. Chlorine tablets or any toilet tank cleaners are also not recommended. When in doubt always check with the toilet bowl manufacturer for more information.

Unfortunately, Serratia Marcescens cannot be completely eradicated, but routine maintenance can keep the bacteria from reappearing or becoming a more stubborn issue.
