Can You Wash Bottles in the Dishwasher

In today’s fast-paced world, convenience is key, and one area where we often seek it is in our kitchen chores. Washing dishes, including bottles, can be a time-consuming task. Many people wonder if they can simplify this process by using the dishwasher. In this article, we’ll explore the topic of washing bottles in the dishwasher, examining the dos and don’ts, safety considerations, and the potential impact on various types of bottles.

The dishwasher has become a kitchen staple for many households, making the chore of dishwashing significantly more convenient. But when it comes to bottles, especially those that hold beverages, the question arises: Can you safely wash bottles in the dishwasher without compromising their integrity or cleanliness? Let’s dive into the dishwasher dilemma and find out.

The Dishwasher Dilemma

Benefits of Dishwasher Cleaning

Using a dishwasher to clean bottles offers several advantages. Firstly, it saves time and effort, especially when you have a load of dishes to tackle. Dishwashers are designed to remove tough stains and sanitize dishes effectively, which can be particularly important for bottles used to store milk, juices, or other beverages. Additionally, the high-temperature wash cycle of a dishwasher can kill germs and bacteria.

Potential Risks

However, there are potential risks associated with washing bottles in the dishwasher. Bottles, depending on their material and design, can be sensitive to high temperatures and aggressive detergents. Glass bottles, for example, may crack or shatter if exposed to extreme heat, while plastic bottles can become deformed or discolored. Moreover, certain bottle components, such as bottle nipples and lids, might not withstand the dishwasher’s cleaning process.

Types of Bottles

Before deciding whether to use the dishwasher for bottle cleaning, it’s essential to consider the type of bottles you have:

Glass Bottles

Glass bottles are generally more durable and heat-resistant than plastic ones. However, they are not immune to potential damage in the dishwasher. It’s crucial to check the manufacturer’s guidelines for temperature limits.

Plastic Bottles

Plastic bottles are more susceptible to heat and may warp or release chemicals if subjected to high temperatures. Always use the dishwasher’s gentle cycle for plastic bottles, if possible.

Stainless Steel Bottles

Stainless steel bottles are often dishwasher-safe, but it’s wise to verify this with the manufacturer’s instructions. They are less likely to be affected by heat, making them a reliable choice for dishwasher cleaning.

How to Safely Wash Bottles in the Dishwasher

If you decide to use the dishwasher for bottle cleaning, follow these steps to ensure it’s done safely and effectively:


  1. Rinse bottles thoroughly to remove any leftover liquids or residue.
  2. Disassemble bottles by removing caps, nipples, and other removable parts.

Loading the Dishwasher

  1. Place bottles securely in the dishwasher’s bottle rack or on the top rack, ensuring they won’t tip over during the wash cycle.
  2. Keep bottle nipples, caps, and other small parts in a dishwasher-safe container or utensil basket.

Choosing the Right Cycle

Select a gentle or baby bottle-specific cycle if your dishwasher offers one. Avoid using the high-temperature sanitize cycle, especially for glass or plastic bottles, as it may lead to damage.

Cleaning Baby Bottles in the Dishwasher

Cleaning baby bottles requires extra care. Always use a baby bottle-specific detergent to ensure the safety of your infant. Additionally, bottle nipples and pacifiers should be thoroughly rinsed and placed in a separate utensil basket to prevent them from falling through the dishwasher’s racks.

Common Myths About Dishwasher Cleaning

High Temperatures and Bottle Damage

Contrary to a common misconception, the high temperatures in dishwashers are not always harmful to bottles. Many bottles, particularly stainless steel ones, can withstand these temperatures without issues. However, it’s crucial to verify the material and manufacturer guidelines.

Cleaning Effectiveness

Dishwashers are effective at cleaning and sanitizing, but stubborn stains may require pre-soaking or additional attention. Ensure bottles are adequately rinsed before loading them into the dishwasher.

Maintenance and Care

To ensure your bottles remain in good condition over time, practice regular maintenance:

  1. Clean your dishwasher’s filter to prevent residue buildup.
  2. Check bottles for signs of wear, including cracks, discoloration, or loose parts.


In conclusion, washing bottles in the dishwasher can be a convenient and effective method if done correctly. It’s essential to consider the type of bottles you have and follow proper procedures to prevent potential damage. With the right precautions and maintenance, you can enjoy the benefits of dishwasher cleaning without compromising your bottles’ quality.
