Can Baby Bottles Go In The Dishwasher?

Baby bottles play a vital role in providing nourishment and soothing infants. Yet, the question remains: Can baby bottles withstand the dishwasher?

Fortunately, most types of baby bottles can safely go into the dishwasher. However, it’s crucial to check the specific bottle material and manufacturer’s instructions before proceeding.

In this article, I tackle the dishwasher safety of baby bottles, bottle materials, manufacturer guidelines, the proper placing of baby bottles in the dishwasher, and post-dishwashing practices to ensure their cleanliness, safety, and overall sanitation. Let’s begin!

Dishwasher Safety of Baby Bottles

Using a dishwasher to clean baby bottles is not only convenient but also generally safe. The high temperature and its ability to sanitize makes a dishwasher an appealing option for many parents. However, there might be exceptions to note.

For instance, not every baby bottle is dishwasher safe. The high temperatures inside the dishwasher could cause some bottles, especially those made of plastic, to warp, degrade, or even release harmful chemicals. 

Therefore, a key step is to ensure that the specific baby bottles you have are indeed able to withstand the dishwasher’s cleaning process. Be diligent about taking note of labels on the packaging or markings on the bottles that specify whether they are dishwasher safe.

Also remember, what’s safe for one dishwasher might not be safe for another, as different models may have different temperature settings. So, the safety instructions for the bottles should align with your specific dishwasher’s guidelines.

Checking Bottle Material and Manufacturer Instructions

Following manufacturer instructions and considering bottle material is crucial when deciding to clean baby bottles in a dishwasher. These factors significantly impact the safety and longevity of the bottle.

The material of the baby bottle plays a considerable role in its durability in the dishwasher. For example, certain plastics may warp from the heat, while glass bottles are generally more heat-resistant and safer to pop in the dishwasher. However, plastic bottles marked as dishwasher safe have usually been tested to withstand the heat without releasing any harmful chemicals.

Manufacturer instructions are there for a reason, and they vary widely depending on the specific type and brand of a baby bottle. Therefore, make sure to read and follow these guidelines closely. They provide valuable information on how to safely and effectively clean the bottle, which can help prevent damage and ensure the bottle remains safe for your baby’s use.

Preparation: Disassembling and Rinsing Baby Bottles

The right preparation is key when you’re going to wash baby bottles in a dishwasher. The first step is disassembling the bottle before placing it in the dishwasher.

Disassembling the bottle means taking apart all its components like the bottle itself, the nipple, the lid, and any other separate parts it may have. This ensures all surfaces are exposed and can be properly cleaned.

It’s also crucial to rinse the bottles before placing them in the dishwasher. The residue of baby formula or breast milk can harden and may not get cleaned off properly during the dishwasher cycle.

Proper Loading of Baby Bottles in Dishwasher

Proper loading of baby bottles and their components in the dishwasher is crucial to ensure a thorough cleaning job is done. The incorrect placement could lead to less effective cleaning or even potential damage to the items.

Firstly, always place baby bottles and their smaller components on the top rack of the dishwasher. This position is usually less intense, further away from the heating element, and more secure, which helps prevent the bottles from being dislodged during the wash cycle.

Also, keep in mind it’s better to space items out. Overcrowding can lead to uneven washing as the water won’t be able to reach all surfaces sufficiently.

For small items, like nipples and caps, consider using a dishwasher basket. This prevents small pieces from falling through the rack, making sure they’re kept safe during the wash cycle, and you don’t find them melted on the dishwasher’s heater.

Choosing the Right Dishwasher Cycle and Detergent

Choosing the right dishwasher cycle and detergent is another important part of cleaning baby bottles safely and effectively. Each of these decisions plays a significant role in ensuring the bottles are thoroughly cleaned and sanitized.

Ideal Dishwasher Cycle

The ideal dishwasher cycle for baby bottles will typically be indicated in the manufacturer’s instructions. Some baby bottles may be safe on the normal cycle, while others might require a gentle cycle to prevent damage. If your dishwasher has a ‘sanitize’ cycle, you could consider using it as it heats the water to a higher temperature, helping to kill more germs.

Detergent Choice

When it comes to detergent, choosing a mild option without harsh chemicals is a good idea. Some conventional dishwasher detergents may be too strong for baby items. Instead, opt for detergents labeled as baby-safe or those that are free from dyes, fragrances, and phosphates. This ensures that the bottles aren’t exposed to any potentially harmful chemical residues.

Drying the Baby Bottles Post Dishwashing

Once the dishwasher cycle is complete, it’s important to properly dry baby bottles to prevent possible contamination. Excess moisture may promote bacterial growth, hence correct drying techniques are essential.

One way to dry baby bottles efficiently is to let them air dry completely. Remove the items from the dishwasher and place them on a clean, dry dish towel with all parts separated to allow air to circulate and reach all surfaces. Avoid using a towel to manually dry the inside of the bottle or other parts since this could introduce germs.

Bear in mind, it’s key not to reassemble the bottle until all elements are completely dry. Reassembling while parts are still wet can trap moisture and create an environment for bacteria to grow.

Sterilizing Baby Bottles: Necessary or Not?

The necessity of sterilizing baby bottles after dishwashing is a common concern among parents. The need for further sterilization primarily depends on your baby’s age and health condition, along with the safety of your water supply.

For newborns or infants with weakened immune systems, additional sterilization can provide an extra level of protection against potential bacteria. However, for older babies and toddlers, the sanitizing effect of a dishwasher cycle, especially if it has a ‘sanitize’ setting, is usually sufficient on a daily basis.


In conclusion, using a dishwasher to clean baby bottles is generally safe and indeed time-saving for busy parents. However, it’s important to remember to first check the bottles for dishwasher-safe labels or follow the manufacturer’s instructions to ensure their safety. Always remember, when it comes to your baby’s health, it’s better to err on the side of caution.
