Why Do Baby Bottles Go Orange In Dishwasher?

Are you experiencing discoloration issues after every time you wash your baby’s bottles? Don’t feel alone if you are. Almost all moms face such issues as bottles going orange even after washing them in a dishwasher.

And if you’re wondering why do baby bottles go orange in dishwasher, it can happen due to several reasons.

Any baby bottle can go orange in the dishwasher due to the fat layer of baby formula milk or breast milk. Besides the milk fat layer, high temperature, cleaning with other dishes, and the bottle material are also key reasons to experience discoloration issues.

Well, the good news is you can get rid of the discoloration issue. So, let’s get you through the reasons and reliable guide for getting rid of this issue.

Why Do Baby Bottles Go Orange In Dishwasher?

Your baby’s bottles are getting orange for a couple of reasons. Here, we’ve included those reasons that contribute to bringing the orange appearance in your baby bottle after putting them in a dishwasher. Have a look:

Why Do Baby Bottles Go Orange In Dishwasher

1. Milk’s Fat Layer:

Milk fat layer is one of the reasons that bring the orange stains in a baby’s bottle in a dishwasher. When you put the baby bottle in a dishwasher, it may thoroughly clean the bottle but cannot be able to remove the stains.

That is because the fat layer of baby formula milk and breast milk can cling to the bottles inside. And the fat only can be removed through scrubbing, and sadly the dishwasher doesn’t have any scrubbing facilities.

2. Food Pigmentation:

Alongside formula milk and breast milk, using a baby bottle to feed juice or other liquids is common. And sadly the dishwasher is not capable enough to clean food and drink pigmentation. Moreover, feeding fruit juice of blueberries and strawberries is the core reason for discoloration with your baby bottle.

However, you can use an ideal dishwasher for baby bottles, but sometimes you can see orange stains on them. These are just perfect for baby bottle stains and other products that your baby uses.

3. Washing Bottles With Other Dishes

Another reason to have orange stains after washing your baby’s bottle in the dishwasher is to clean it with other kitchen utensils. Not only you, but many parents clean their baby products with other foods and the pigment of different foods causes orange spots. And most of the time, tomato-based foods are the main culprit that causes bottles’ color.

4. Hot Temperature (Uses Baby Bottles That Are Not Safe in the Dishwasher)

If you’re not using a dishwasher-safe baby bottle, then you should never put it in the dishwasher. Silicone and plastic bottles can easily lose their original appearance if you place them in hot water.

Since dishwashers clean the dishes with the help of dish detergent, other components, and hot water, putting bottles on the dishwasher can cause discoloration. Always check the bottle’s manual if it’s dishwasher safe or not.

5. Wrong Cleaning Solution

Last but not least, using the wrong cleaning solution while cleaning your baby bottle in the dishwasher can cause orange stains. Using a cleaning solution packed with abrasive and harsh ingredients will cause orange or black spots on your bottles.
