Reasons For Yellow Stains On Baby Bottle Nipples

There are several causes of yellow stains in bottle nipples. Some could be as basic and harmless as fat deposited on the surface of the nipples, while others could mean more. 

Here are some primary causes of yellow stains on bottle nipples:

Fat Residue

Fat deposits are one common reason for yellowing in bottles and bottle nipples. Usually, some parents are fond of just rinsing the bottles without using liquid soap or detergent to wash them.

If you put a finger into a bottle rinsed without soap, you’ll feel the oil left in them. Over time this oil undergoes discoloration and appears cloudy or yellowish in the bottles.

Pigmentation

The pigments in some foods like formula milk, juices, flavored drinks, or colored vegetables and fruits like beetroot, strawberry, spinach, or tomatoes can also cause discoloration in bottle nipples.

When you blend these vegetables and fruits, their pigments deposit in the bottles and cause discoloration if not properly washed.

Cleaning Agents

Using harsh chemicals on these materials can cause abrasions that will absorb stains and make cleaning harder.

Even though excessive scrubbing can help in some cases, it is the reverse for baby bottles, as excessively scrubbing them can make them appear dirtier.

Dishwashing Baby Bottle

If you put the baby bottle in a dishwasher alongside other dishes, the bottle can pick up new stains from the dishes.

Calcium Build-up

Using hard water to wash the bottles can also lead to color changes in the bottle. This is not just for the bottle alone; hard water generally leads to discoloration on materials like clothes and plastic and is bad for the skin.

High-Temperature Water

To sterilize the bottles, some parents use high-temperature water to soak them to kill any germs that may cling to them. Even though this will effectively kill the germs, it’ll affect the appearance of the bottles and give them a worn-out look.

However, if you already use a bottle with yellow stains on the nipples, here are practical tips on how to get rid of the stains:

  • Wash the bottles after every use. It’s not enough to rinse out any milk remnants in the bottles. It is also not hygienic. Use a mild detergent to create soapy water. Then use a soft brush to wash the bottles thoroughly before storing them.

Mix two tablespoons of vinegar in two cups of water or enough volume to submerge the bottles and soak them for 30 minutes. Vinegar will not just clean but also sterilize the bottle of any bacteria.
  • After using vinegar, run a cold water rinse on the bottles to remove any leftover vinegar to prevent milk curdling.
  • If there are still stains after you use vinegar, use baking soda.
  • Add a tablespoon baking soda to a warm water bottle and leave it overnight. Use the solution to scrub the bottle with a silicone brush.

These steps will eliminate the stubborn stains and persisting odor in the bottles.
