Read on to find out more about dealing with the pink discoloration and prevention measures to ensure that your toilet doesn’t get them again in the future.
What is the Pink Ring Toilet?
The pink discoloration normally appears in pale shades of colors between blue and red. It usually looks like a ring that accumulates at the water line in the bowl or tank.
Other than the toilet, the stains can be seen in many other areas such as the kitchen sink/drain, shower curtains, tubs, and heads, as well as pet bowls.
The major source of the pink discoloration is bacteria. The pink spots can also be a result of mineral deposits and leakages.
Serratia Marcescens Toilet Mold
The most common cause of the pink discoloration an airborne bacteria called Serratia Marcescens that settles as a pinkish-gray film on a moist surface such as the toilet bowl or underneath the tank.
The bacterial pink ring looks like orange or pink mold, but it’s actually not mold. Orange mold is fungus while the pink ring is a colony of airborne bacteria.
Serratia Marcescens is naturally found in soil, food or animals. The bacteria produce a characteristic pinkish-red pigment, that develops well in damp areas with moisture, dust, fats, and phosphorus-laden ingredients such as soaps, gel, human waste, shampoos, and some food products.
There is plenty of water and phosphates (from soap) in the toilet or bathroom that provide a conducive environment for the bacteria to survive.
Owing to the fact the bacteria is airborne, it can be moved to any place and it can survive as long there is moisture.
Iron & other Mineral Deposits
The other possible reason pink discoloration appears in your toilet is remnants of iron and other minerals (such as manganese, and copper) found in the piping system of the house.
The stains from mineral deposits can also be orange in color and they also collect just above the water line.
Leakages in your plumbing system that allow moisture to escape and accumulate on different surfaces in your house can habitats for Serratia Marcescens

Be careful not to use extremely strong scrubbers like a pumice stone or a bristle brush as they can harm the protective sealant added to protect the coating of the toilet bowl.
Aggressive cleaning can also cause the bowl to be more susceptible to the growth of mildew, mold, and other opportunistic fungi.
Method #3 Dealing with Pink Toilet Stains from Mineral Deposits

One of the most common remedy is to sock the stains in an acidic solution of lemon juice and vinegar. The solution easily dissolves the minerals and making it easy to clean them off.
